ABSTRACT Recent studies underscore the beneficial impacts of oral natural plant extracts on human skin health, though clinical evidence of their efficacy and safety is limited. This study evaluates the skin health effects of a novel oral supplement containing Rosa roxburghii, Punica granatum, and rose extracts (RPR) 0.70 healthy female participants were randomly assigned to either a control group or an RPR group, with the latter ingesting 20 mL of the RPR supplement daily on an empty stomach over 8 weeks. After 8 weeks, the RPR group exhibited significant enhancements (p < 0.001) in skin hydration, glossiness, elasticity, and skin tone, with increases of 69.02%, 30.48%, 25.97%, and 7.52%, respectively. Concurrently, decreases in skin firmness and melanin levels were observed at 21.17% (p = 0.007) and 25.06% (p < 0.001), respectively. Statistical analysis confirmed that these changes were significantly greater than those in the control group. Image analysis indicated no significant changes in mean optical density of hyperpigmented spots within the RPR group (p = 0.367), but a significant reduction in the areas of hyperpigmented spots, under‐eye fine lines, and crow's feet by 41.50%, 37.55%, and 29.36%, respectively (p < 0.001), whereas no significant changes were detected in the control group. Importantly, no adverse effects were observed. These findings suggest that the combined intake of Rosa roxburghii, Punica granatum, and rose extracts can improve skin health, offering a promising natural alternative for dermatological care.

Purpose: This study was designed to study testicular-histopathology and lipid profile against 50ppm of fluoride (ad labitum) exposure in mice. Moreover, the curative potentials of vitamin E, Punica granatum and Olea europea fruit extracts were also studied. Methods: Five groups (10 animals/group) were treated as follow (a) Control (C) (F free water-15 days); (b) NaF {50ppm F-ions in drinking water (10days) and F free water (5days)}; (c) NaF + vitamin E (NaFE) {50ppm F-ions (10days) and F free water+60µg vitamin E in corn oil (5days)}; (d) NaF+ Punica granatum fruit extract (NaFP) {50ppm F ions (10days) and F free water+0.2mL P. granatum fruit extract (5days)}; (v) NaF+ Olea europea fruit extract (NaFO) {50ppm F-ions (10days) and F free water +0.2mL O. europea extract (5days)}; All animals were sacrificed on day 16 to obtain blood for lipid profile and testes for histopathological studies. Results: Results shows peculiar histopathological changes in the testis, including the loss of interstitial tissues, spermatogonia, spermatocytes, spermatids and maturing sperms. These signs were convincingly recovered in NaFO, followed by other two post treatment groups NaFP and NaFE. Similarly the micrometric data shows significant increase in the number of spermatogonia, spermatocytes and developing spermatozoa, in NaFO (CSA of seminiferous tubules, number of spermatogonia, spermatocytes:, sperms embedded in sertoli cells & number of dislodged sperms). The rise of High Density Lipoproteins (HDL) with a simultaneous decline in plasma cholesterol, Low Density Lipoprotein (LDL) and Very Low Density Lipoprotein (VLDL) in NaFO indicate the importance of these post treatments, against altered lipid profile of the F toxicology. Excellent testicular rehabilitation found in NaFO group that indicate the curative potential of O.europea against altered histopatology against F exposure in testes. Conclusions: The severity of the mentioned pathology of NaF group indicates that Olea europea and Punica granatum post treatment can effectively eradicate the toxic changes of F exposure in lipid profile, while Olea europea fruit extract showed more ameliorationative capability against F-exposure in testes.

Pomegranate (Punica granatum L.) is an ancient fruit crop that has been cultivated worldwide and is known for its attractive appearance and functional metabolites. Fruit color is an important index of fruit quality, but the color formation pattern in the peel of evergreen pomegranate and the relevant molecular mechanism is still unknown. In this study, the contents of pigments including anthocyanins, carotenoids, and chlorophyll in the peel of 'Danruo No. 1' pomegranate fruit during three developmental stages were measured, and RNA-seq was conducted to screen key genes regulating fruit color formation. The results show that pomegranate fruit turned from green to red during development, with a dramatic increase in a* value, indicating redness and anthocyanins concentration, and a decrease of chlorophyll content. Moreover, carotenoids exhibited a decrease–increase accumulation pattern. Through RNA-seq, totals of 30, 18, and 17 structural genes related to anthocyanin biosynthesis, carotenoid biosynthesis and chlorophyll metabolism were identified from differentially expressed genes (DEGs), respectively. Transcription factors (TFs) such as MYB, bHLH, WRKY and AP2/ERF were identified as key candidates regulating pigment metabolism by K-means analysis and weighted gene co-expression network analysis (WGCNA). The results provide an insight into the theory of peel color formation in evergreen pomegranate fruit. [ABSTRACT FROM AUTHOR]

Sepsis is an exaggerated immune response resulting from systemic inflammation, which can damage tissues and organs. Acute kidney injury has been detected in at least one-third of patients with sepsis. Sepsis-associated acute kidney injury increases the risk of a secondary infection. Rapid diagnosis and appropriate initiation of antibiotics can significantly reduce mortality and morbidity. However, microorganisms are known to develop resistance to antibiotics. Estimations indicate that the annual casualties caused by microbial resistance will surpass cancer fatalities by 2050. The prevalence of bacterial infections and their growing antibiotic resistance has brought immediate attention to the search for novel treatments. Plant-derived supplements contain numerous bioactive components with therapeutic potential against a variety of conditions, including infections. Punica granatum peel is rich in phenolic compounds. The purpose of this study was to determine the anti-inflammatory and anti-bacterial properties of P. granatum peel extract (PGPE) on lipopolysaccharide (LPS)-induced acute kidney injury. Experimental groups were Control, LPS (10 mg/kg LPS, intraperitoneally), PGPE100, and PGPE300 (100 and 300 mg/mL PGPE via oral gavage, respectively, for 7 days). According to biochemical results, serum blood urea nitrogen (BUN), creatinine (Cr) and C-reactive protein (CRP), kidney tissue thiobarbituric acid reactive substances (TBARS), and reduced glutathione (GSH) levels significantly decreased in the PGPE groups compared to the LPS group. Histopathological and immunohistochemical findings revealed that toll-like receptor 4 (TLR4) level and nuclear factor kappa B (NF-κB) expression increased in the LPS group compared to the Control group. In addition, the anti-Gram-negative activity showed a dose-dependent effect on Acinetobacter baumannii, Escherichia coli, and Pseudomonas aeruginosa with the agar well diffusion method and the minimal inhibitory concentration (MIC). The MIC value was remarkable, especially on A. baumannii. We conclude that PGPE has the potential to generate desirable anti-bacterial and anti-inflammatory effects on LPS-induced acute kidney injury in rats. [ABSTRACT FROM AUTHOR]

The aim of this study was to evaluate the feasibility of producing a gel from pomegranate peel extract for topical application, specifically for antimicrobial and wound healing purposes. Initially, the dry crude pomegranate peel extract (DCPPE) was analyzed for its phenolic profile using HPLC and by determining the total phenolic content (TPC), and total antioxidant activity (TAA). Carbomer-based gels were prepared and subjected to antimicrobial susceptibility tests to determine the optimal concentration of DCPPE (1.25 %, 2.5 %, and 3.75% w/w) in the formulations. Then, gel was produced in larger quantities and submitted to physicochemical and microbiological tests after being stored at room temperature or under refrigeration for 90 days. Gallic acid, ellagic acid, and punicalagin A and B were identified in DCPPE. The TPC was measured at 61.92 mg of gallic acid equivalent per gram (mg.GAE. g −1) and the TAA was 93.8 % (solution at 40 µL.mL−1), demonstrating superiority over butylhydroxytoluene (BHT) and gallic acid solutions at equivalent concentrations. Antimicrobial susceptibility tests indicated a significant difference (p < 0.05) for the 2.5% w/w DCPPE gel against Staphylococcus aureus and Candida albicans , which was the chosen concentration. Over a 30-day period under both storage conditions, there was no significant difference in pH values, and the reduction of TPC in the refrigerated formulation was <10 %, indicating good stability. Furthermore, the in vitro antimicrobial activity of the gel remained effective against all tested strains. These results suggest that the medicinal carbomer-based gel with DCPPE at 2.5% w/w has potential as a pharmaceutical form for antimicrobial and wound healing purposes. The utilization of DCPPE as a pharmaceutical bio-input for the gel is a sustainable approach to valorizing pomegranate peel biowaste. [Display omitted] • Standardization of DCPPE gel formulation was achieved. • The total phenolic content in the refrigerated gel remained above 90 % for 30 days. • Low concentrations of DCPPE gel demonstrated excellent antimicrobial activity. • DCPPE shows promise as a bio-input for pharmaceutical applications.

Ectomyelois ceratoniae and Deudorix livia are the main pests of pomegranate Punica granatum L. in Tunisia. This study was carried out to investigate the susceptibility of five Tunisian pomegranate varieties (Tounsi, Guebsi, Gares, Zehri, and Baldi) from two oases (Gafsa and Degache) to infestation by E. ceratoniae and D. livia during fruit ripening. To this end, the physico-chemical properties of these pomegranate varieties were quantified during the ripening period and correlated with insect infestation. The results showed that all varieties were infested by E. ceratoniae and D. livia and that the severity of the infestation depended strongly on the pomegranate variety and the ripening stage of the fruit. It was observed that the infestation caused by E. ceratoniae was early as compared to D. livia on all the pomegranate varieties at two oases conditions. Moreover, results showed that biochemical and physico-chemical properties changed during fruit maturity. The total soluble solids (TSS), sugars, maturity index, fruit peel water content, and fruit weight are significantly increased but the titratable acidity and peel hardness are significantly decreased with ripening stage. The results pointed out that pomegranate infestation varied depending on the morphological changes of the fruit. In addition, a significant correlation was observed between E. ceratoniae and D. livia infestation and fruit juices TSS (r = 0.36 and r = 0.68), maturity index (r = 0.44 and r = 0.35), and total sugar (r = 0.36 and r = 0.67). Analyses also revealed a high negative correlation between fruit peel hardness and D. livia infestation (−0.63). The findings of this research will enhance comprehension regarding the behavior of D. livia and E. ceratoniae, which infest various pomegranate cultivars in Tunisian oases. Consequently, this will facilitate the refinement and implementation of management approaches aimed at addressing both species. For instance, early harvesting of fruits at the onset of ripening, prior to pest activity can significantly reduce levels of pomegranate infestation. [ABSTRACT FROM AUTHOR]

Repairing the skin barrier with moisturizers is one of the five main pillars of treating atopic dermatitis. Petrolatum is considered the gold standard, but its consistency is too thick and oily making it less comfortable to use. Moisturizers containing pomegranate extract (Punica granatum) can be an alternative choice that is more comfortable to use. The effectiveness of this pomegranate extract can be evaluated using TEWL and pH examinations which are considered accurate indicators for changes in skin barrier conditions. Effectiveness of topical administration of 0.1% pomegranate extract in reducing TEWL and skin pH in sufferers with a history of AD. Single blind randomized clinical trial with two parallel group pre and post design. 34 sufferers with a history of AD were randomly divided into treatment groups (topical 0.1% pomegranate extract, 17 subjects) and control group (topical 100% petrolatum, 17 subjects). Moisturizer was applied twice daily to the volar area of the forearm for 4 weeks. Both groups showed a significant decrease in TEWL after 4 weeks with a TEWL delta of -5.2±2.31g/m2/hour (p<0.001) in the pomegranate extract group and -7.0±7.95g/m2/hour (p=0.003) in the petrolatum group. There was no significant difference in TEWL reduction between the two study groups.The pomegranate extract group showed a significant decrease in pH after 4 weeks with a pH delta of -0.5±0.10 (p<0.001), while the petrolatum group actually showed a slight increase with a pH delta of 0.0±0.59 (p=0.6). The pomegranate extract group showed a significantly greater decrease in pH (p<0.001).Topical 0.1% pomegranate extract is as effective as 100% petrolatum in reducing TEWL, but more effective in lowering skin pH.

• Anthocyanins are major phytochemicals present in the aril extracts of Southern African P. granatum 'Wonderful' cultivar. • The methanolic extract induced the strongest cytotoxicity in breast cancer MCF-7 cell line. • By regulating the proteins involved in apoptotic pathway, the extract treatment of MCF-7 cells enhanced the cell death by inducing apoptosis. Due to its superior nutritional, health promoting and disease preventing qualities, the Punica granatum is referred to as a "Super Fruit" and has been traditionally used for its therapeutic properties including cancer prevention. Although this plant is grown globally, phytochemical profile and their biological properties varies based on the pedoclimatic variables, fruit's phenogenotype, stage of ripeness, pre- and post-harvest circumstances, and extractive solvent, even among the same cultivars grown under various conditions. Here, we investigated the phytochemical composition and anticancer potency of three different aril solvent extracts (methanol, chloroform, and ethyl acetate) of South African 'Wonderful' cultivar against human breast cancer MCF-7 cell line. The identification of major phytochemical constituents of three different extracts was performed by UHPLC-Q-TOF-MS2. Total phenolic and flavonoid content were determined using the Folin–Ciocalteau and aluminium chloride colorimetric methods, respectively. Cell viability was assessed by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) reduction and adenosine triphosphate (ATP) content assays. The apoptotic effects were determined by morphological analysis (phase contrast and LIVE DEAD assay) and FITC-Annexin/ Propidium Iodide flow cytometry assay, Cytochrome-c release, caspase activation assay and ratio of Bax/Bcl-2 expression. UHPLC-Q-TOF-MS2 analysis of extracts revealed the presence phenolic acids, flavonoids, anthocyanins, tannins, coumarins, gallotannins, lignan, and phthalide. The total phenolic and flavonoid content was determined to be highest for methanol extract (91.78±1.55 mg GAE/g DM and 43.03±2.63 mg QE/g DM respectively). This correlated with its highest cytotoxic activity against MCF-7 cells compared to other two solvent extracts with IC 50 concentration ∼289 and ∼229 μg/mL at 24 and 48 h respectively. After 48 h, the apoptotic cell population were significantly increased with 400 μg/mL methanol extract treatment as observed via morphological changes and FITC-Annexin/ Propidium Iodide assay. The methanol extract significantly induced apoptosis via the release of cytochrome-c, increase in ratio of Bax to Bcl-2 and caspase-8 and 9 activations. Based on the present findings, we conclude that South African P. granatum 'Wonderful' cultivar had the potential as cytotoxic and apoptosis inducing anticancer agent, which is worth investigating in detail.

Infectious diseases are caused by pathogenic microorganisms, mainly bacteria, viruses, parasites and fungi, and represent a threat to public health. In the state of Paraíba, Brazil, several plant species are widely used in traditional medicine to treat infections caused by pathogenic microorganisms. From this perspective, the present study aimed to carry out a bibliographic survey of plants used in the treatment of infectious diseases by local communities and to identify the species that have already been investigated in clinical trials. The scientific documents were retrieved from different databases. A total of 31 species distributed in 22 families are used against infections by traditional communities in different municipalities in Paraíba. However, only 8 species have had their herbal products evaluated in clinical trials. Mouthwashes containing Aloe vera, Anacardium occidentale and Punica granatum have been targeted for dental applications. Considering the urgency in developing broad-spectrum antimicrobials, it is recommended that new randomized clinical trials be developed to investigate the traditional uses of other medicinal plants against infectious diseases reported in this study.

A study was conducted in the district of Rawah, which is located 224 km away from the city of Ramadi, on the pomegranate trees of the seedless Rawa cv.. The study investigated the effect of fruit bagging and calcium spray on some fruit traits. Two factors were studied during the research: the first factor involved using different types of bags to cover the fruits, including (uncovered control, double-layer muslin cloths, saran, and white paper bags). The second factor included calcium spraying at concentrations of 0, 1, and 2 g per liter. The results indicated that fruit bagging treatments had a significant effect on all studied characteristics except for the percentage of calcium in the fruit peels. Saran bagging contributed to achieving the best results for characteristics (fruit weight and yield) at 407.04 g and 23.27 kg tree-1, respectively. Furthermore, the above treatment resulted in the lowest percentage of cracked fruits at 13.43%. Conversely, the treatment of bagging with white paper bags achieved the highest value for the fruit firmness characteristic at 2.43 kg cm2. As for the calcium spray, it showed a significant effect on all studied characteristics. The high concentration (2 g liter-1) achieved the best values for fruit weight, fruit firmness and yield, at 415.72 gm, 2.49 kg cm2 and 24.03 kg tree-1) respectively. Additionally, the above treatment resulted in the lowest percentage of cracked fruits at 15.24%, While, the treatment (1 g liter-1) achieved the best value for percentage of calcium in the fruit peels at 1.32%. The interaction between the two study factors reached a significant level of influence on all studied characteristics. The interaction treatment (B2C2) excelled in achieving the best values for most of the studied characteristics, while the control treatment (B0C0) showed the lowest values for the studied characteristics.

Abstract Pomegranate (Punica granatum) is a tree of the Punicaceae family that is widespread all over the world and has several types and therapeutic uses. The current study aimed to investigate the phytochemical compounds by GC analysis and carried out physical characterization of the pomegranate seed oil and its self-nanoemulsifying system. Then antioxidant, anti-diabetic, and anti-lipase activities were investigated for both.The pomegranate seed oil was extracted, and its self-nanoemulsifying system was then prepared. Phytochemical compounds were analyzed by GC, and physical characterization was established of the pomegranate seed oil and its self-nanoemulsifying system. Then antioxidant, anti-diabetic, and anti-lipase activities were investigated for both.The GC–MS analysis revealed that punicic acid, β-eleosteric acid, catalpic acid, α-eleosteric acid, and oleic acid were the most predominant compounds in pomegranate seed oil. Other active compounds like linoleic acid, palmitic acid, stearic acid, and α-linolenic acid were detected in trace percentages. The self-nanoemulsifying system was prepared using various concentrations of surfactant (Tween 80), co-surfactant (Span 80), and pomegranate seed oil. The selected formulation had a PDI of 0.229 ± 0.09 and a droplet size of 189.44 ± 2.1 nm. The free radical scavenging activity of pomegranate seed oil, the self-emulsifying system, and Trolox was conducted using DPPH. The oil-self-nanoemulsifying system showed potent antioxidant activity compared to Trolox. Also, pomegranate oil inhibited α-amylase with a weak IC50 value of 354.81 ± 2.3 µg/ml. The oil self-nanoemulsifying system showed potent activity compared to acarbose and had a weaker IC50 value (616.59 ± 2.1 µg/ml) and a potent IC50 value (43.65 ± 1.9 µg/ml) compared to orlistat.Pomegranate seed oil self-nanoemulsifying system could be applied in the future for the preparation of possible oral medications for the prevention and treatment of oxidative stress, diabetes, and obesity due to its high activity against free radical, amylase, and lipase enzymes compared to pomegranate seed oil itself and the references used. This study reveals that self-nanoemulsion systems can enhance oil drug formulations by improving pharmacokinetics and pharmacodynamics, acting as drug reservoirs, and facilitating efficient oil release.

This study explored the inhibitory effect of pomegranate flower polysaccharide (PFPS) on mastitis through in vitro and in vivo models. PFPS is a new type of polysaccharide isolated and extracted from pomegranate flowers. The result revealed that PFPS consists of GalA, Ara, and Gal, and the residues consist of 1,4-GalpA, 1,4-Galp, and 1,3,6-Galp, which contain HG-type and RG-I-type pectin structural domains. In vitro studies showed that PFPS could inhibit LPS-enhanced phagocytosis of RAW 264.7 cells and the release of IL-1β, IL-10, and TNF-α. In vivo, studies showed that PFPS improved xylene-inducedmouse ear swelling and carrageenan-induced mouse paw edema by inhibiting inflammatory factors. In the mouse mastitis model, PFPS significantly improved LPS-induced inflammation and oxidative stress in mammary tissue. Intestinal flora sequencing results showed that PFPS could effectively regulate the intestinal flora of mice, reduce the relative abundance of pathogenic bacteria Oscillospira and AF12, and increase the probiotics Blautia, Parabacteroides, Allobaculum, and Clostridiaceae&lowbar;Clostridium. Therefore, PFPS ultimately played a role in preventing mastitis by regulating the intestinal flora and further improving the blood-milk barrier. This study provides a scientific basis for PFPS as a potential candidate drug for the treatment of mastitis. [ABSTRACT FROM AUTHOR]

Nonalcoholic fatty liver disease (NAFLD) is a disorder in which excess fat accumulates in hepatocytes and can lead to serious complications. Oxidative stress is one of the leading causes of NAFLD. Pomegranates are considered antioxidant‐rich fruit. This systematic review study was aimed to investigate the impact of pomegranate on NAFLD. PubMed, Scopus, and Google Scholar databases/search engines (from inception up to July 2023) were searched for interventional studies (human and animal) that examined the effects of supplementation with different parts of pomegranate including fruits, peels, seeds, or flower on NAFLD outcomes. A total of 222 articles were retrieved following the initial search. After excluding duplicates, the title and abstract of 114 articles were screened. Afterward, irrelevant articles were removed and the full texts of the remaining 27 articles were reviewed. Eventually, 19 articles (16 animal and three human interventional studies) that met the inclusion criteria, published between 2009 and 2023, were included in this systematic review. Our study indicates the potential beneficial effects of different parts of pomegranate on the improvement of NAFLD. However, given that the majority of the included articles were animal studies, further investigations in the form of human clinical trials are warranted to suggest a clinical indication of such interventions.

The sustained higher profitability of a pomegranate orchard relies heavily on the production of a greater proportion of high-quality fruits, a goal achievable through the implementation of effective management practices. The objective of this study is to provide site-specific supplementary knowledge regarding the response of pomegranate plants to various management practices under arid conditions. With the aim of enhancing both marketable fruit yield and quality of pomegranate in arid regions, four separate and simultaneous experiments were conducted in the same orchard to evaluate (i) the response of planting materials derived from tissue culture, air layering, and cutting; (ii) the impact of crop (fruit) load; (iii) the response of crop regulation; and (iv) the application response of organo-mineral fertilizers containing potassium (OMF-K) and phosphorus (OMF-P). The results obtained for plant growth, fruit yield, and fruit quality did not exhibit significant differences among pomegranate plants raised through the three different methods of vegetative propagation. Striking results in terms of producing superior-grade fruits, higher marketable yield, and overall fruit quality were achieved with crop loads of 80 fruits per plant. Staggering the crop regulation from June to September effectively extended the harvesting season to four months, from the last week of November to March, with eventual benefit of reduced fruit cracking compared to the standard two-month harvesting period obtained from normal regulation. Soil application of the indigenously developed OMF-K in two equal splits, along with the recommended N and P through inorganic sources, significantly reduced fruit cracking (only 6.23%) compared to the recommended NPK through inorganic sources (26.9%), while maintaining similar physicochemical quality attributes.

Background: Giardia intestinalis is a flagellate protozoan that infects both humans and animals. Formation of reactive oxygen species (ROS) during several physiological processes in tissues and cells is indicative of the pathogenesis of different parasitic infections involving Giardia lamblia. Objectives: the current study aimed to assess the potential effects of Punica granatum on interactions of G. intestinalis with the intestinal barrier and its role in ameliorating oxidative stress in a murine model using serum biochemical analysis of both malondialdehyde (MDA) and reduced glutathione (GSH). Methodology: Five experimental groups were involved: Group I included control healthy, group II included infected untreated, group III included infected-treated with metronidazole, group IV included infected-treated with P. granatum, Group V received P. granatum for seven days before and also during induction of infection then regular administration of the drug for an additional seven days. Results: The highest serum levels of MDA (nmol/ml) were expressed in group II 7.03 ± 0.19 followed by group IV that was 5.29 ± 0.62 then group V 4.17 ± 0.28, while group III had 3.58 ± 0.18. On the other side, the highest serum levels of GSH (nmol/ml) were expressed in group V 9.93 ± 0.18, followed by group IV 7.41 ± 0.19 nmol/ml, while in group III was 6.11 ± 0.40. Group II had 5.00 ± 0.15 nmol/ml. There was significant difference between different groups. Conclusions: Decreased expression of MDA in prophylactic and treated groups by P. granatum, moreover increased expression of GSH in group V prophylactic group explains the protective effect of P. granatum against lipid peroxidation and oxidative stress induced by Giardia infection.

In the face of the escalating global antibiotic resistance crisis, exploring alternative therapeutic avenues has become imperative. This study investigates the antibacterial potential of Punica granatum and Rhamnus sp. extracts from Dhahran, Saudi Arabia. Antibacterial activities were evaluated against Pseudomonas aeruginosa, Escherichia coli, Staphylococcus aureus, and Enterococcus faecalis using well diffusion, MIC, and MBC assays. The antibacterial tests of both plants revealed that ethanolic extracts demonstrate superior activity compared to chloroform extracts. Also, Enterococcus faecalis proves most susceptible (up to 33 mm inhibition), while Escherichia coli exhibits notable resistance. Although Escherichia coli was the most resistant organism using MIC, Pseudomonas aeruginosa was the most susceptible strain with MIC less than 12.5 mg/mL. The Punica granatum extracts and Rhamnus sp. chloroformed extract display primarily bactericidal effects, whereas the ethanolic extract of Rhamnus sp. has a mainly bacteriostatic effect. Phytochemical analysis reveals a rich composition, including different well-known antimicrobial chemical classes. These findings underscore the potent antibacterial activity of both plants against diverse bacterial strains. The study emphasizes the need for further research into their phytochemical characterization and mechanistic insights. [ABSTRACT FROM AUTHOR]

Food and beverages with healthy and functional properties, especially those that prevent chronic diseases, are receiving considerable interest among consumers and researchers. Among the products with enhanced properties, fermented beverages from non-grape wines have a high potential for growth. Pomegranate (Punica granatum L.) is a super fruit known for its richness in bioactive compounds that have been reported to have several therapeutic properties against non-communicable diseases. Diverse products can be obtained from the valorization of pomegranate fruit, including wines, supplements, dried arils, juices, vinegar, and syrup. There is no literature evidence of the optimization of the fermentation processes of pomegranate juice that explores the relationships between multiple factors and their interactions. This review provides an overview of the composition of pomegranate fruit and the related health benefits for human health. It also discusses the ways in which pomegranate wine fermentation is impacted by pre-fermentation and fermentation factors. Additionally, it highlights the different subjective and objective techniques for analyzing pomegranate wine quality and the advancement of technologies such as sensors to replace traditional methods of sensory evaluation. It provides comprehensive insights into how different fermentation factors interact and can improve the bioprocess, leading to the production of high-quality wine. [ABSTRACT FROM AUTHOR]

Rheumatoid Arthritis (RA) is regarded as a long-term autoimmune disorder, which triggers inflammation in joints and distresses the organs in the body. Nanotechnology, a science-based technique is a tremendously growing-field with numerous applications where nanoparticles are used to resolve the complications in the habitual life. While comparing to other metals, iron oxide nanoparticles (Fe2O3 NPs) were synthesized at minimal cost using eco-friendly natured materials and also has ability to deliver drug at a specific targeted site. In the present study, a topical nanoemulgel was formulated using Fe2O3 NPs synthesized from Punica granatum. The results of Fe2O3 NPs characterization divulged that the particles were sphere-shaped in nature and the bioactive compounds from the extract acted as capping and reducing agents. Nanoemulgels (F1 to F5) were formulated using different concentrations of Fe2O3 NPs and characterized. Among the formulations F4 nanoemulgel revealed good stability with a zeta potential charge of −53 mV and a polydispersity index of 0.24. L929 cells were treated with F4 formulation and this confirmed that the formulation was non-toxic to normal cells. F4 treated MG63 cell lines revealed the anti-inflammatory property (IC50 = 90.77 μg/ml) of the nanoemulgel. Thus, nanoemulgel containing Fe2O3 NPs synthesized from P. granatum can be an effective, eco-friendly and cost-effective approach to treat RA. [ABSTRACT FROM AUTHOR]

This study investigates sustainable extraction protocols for the recovery of bioactive compounds from by-products of various pomegranate (Punica granatum L.) cultivars, including Acco, Hicaz, Jolly Red, Parfianka, Valenciana, and Wonderful, generated during the industrial processing of the fruits. Advanced extraction technologies, including ultrasounds, microwaves, and hydrodynamic cavitation, have been compared to conventional extraction procedures and utilized to enhance extraction efficiency while also minimizing environmental impact. Water-based extraction methods have been utilized to promote the development of sustainable and eco-friendly processes. The comparison between conventional extractions and ultrasound-assisted extractions (UAEs) and microwave-assisted extractions (MAEs) demonstrated notable improvements in extraction yields, particularly for ellagitannins (punicalins, punicalagins, and ellagic acid) and total polyphenols, with increases ranging from about 45 to 200%. However, the increases directly comparing UAEs to MAEs ranged from about 4 to 6%. This indicates that while both UAEs and MAEs offer notable improvements over conventional extractions, the differences in extraction efficiency between the two advanced methods were relatively modest. These advancements were observed across various pomegranate cultivars, highlighting the versatility and effectiveness of these methods. Notably, hydrodynamic cavitation-based extractions (HC) emerged as particularly promising, consistently yielding the highest levels of bioactive compounds (ellagitannins and total polyphenols), especially when operated at higher frequencies. Compared to conventional extractions, HC exhibited substantial increases in extraction yields for Wonderful pomegranate by-products, surpassing the efficiency of both UAEs and MAEs (approximately 45 and 57% for UAE and MAE, respectively, versus about 80% for HC). Among these advanced techniques, HC has emerged as particularly promising, yielding the most favorable results and leading to significant improvements in the yield of bioactive compounds. When directly compared to UAEs and MAEs, HC increased extraction yields by over 20%. Furthermore, HC allowed for shorter extraction times. The Wonderful cultivar consistently exhibited the highest levels of ellagitannins and the highest total polyphenol content among all types of extraction procedures used, whether conventional or advanced. This highlights the great potential of the Wonderful cultivar in terms of bioactive compound extraction and underscores its significance in research and applications related to pomegranate processing and utilization. This study suggests that the implementation of these advanced technologies into extraction processes represents a significant advancement in the field, offering a promising avenue for the development of efficient and environmentally friendly extraction methods for obtaining valuable bioactive compounds from pomegranate processing by-products.

Pomegranate waste poses an environmental challenge in Arequipa. Simultaneously, interest in sustainable materials like natural rubber latex (NRL) is growing, with Peruvian communities offering a promising source. This study explores the green synthesis of silver nanoparticles (AgNPs) using pomegranate peel extract and their incorporation into NRL nanofibers for enhanced functionalities. An eco-friendly process utilized silver nitrate and pomegranate peel extract as a reducing and capping agent to synthesize AgNPs. The resulting AgNPs and NRL/AgNPs nanofibers were characterized using imaging and spectroscopic techniques such as UV-vis, TGA, FTIR, XRD, Raman, SEM, and DLS. Green-synthesized AgNPs were spherical and crystalline, with an average diameter of 59 nm. They showed activity against K. pneumoniae, E. coli, B. cereus, and S. aureus (IC50: 51.32, 4.87, 27.72, and 69.72 µg/mL, respectively). NRL and NRL/AgNPs nanofibers (300–373 nm diameter) were successfully fabricated. The composite nanofibers exhibited antibacterial activity against K. pneumoniae and B. cereus. This study presents a sustainable approach by utilizing pomegranate waste for AgNP synthesis and NRL sourced from Peruvian communities. Integrating AgNPs into NRL nanofibers produced composites with antimicrobial properties. This work has potential applications in smart textiles, biomedical textiles, and filtration materials where sustainability and antimicrobial functionality are crucial. [ABSTRACT FROM AUTHOR]

Food production must undergo systems change to meet the sustainable development goals (SDGs). For example, organic farming can be empowered by soil microorganisms with plant growth promotion (PGP) and biocontrol features. In this context, there have been limited studies on pomegranate. We investigated microbial diversity in rhizosphere of the pomegranate "Bhagwa" variety and its potential role in PGP and biocontrol. Both bulk and rhizosphere soil samples were analyzed for their physicochemical properties. Whole metagenome sequencing was conducted using the Illumina NovaSeq6000 platform. Surprisingly, we found that bulk and rhizosphere soil samples had comparable microbial diversity. Metagenome sequencing revealed the abundance of Streptomyces indicus, Bradyrhizobium kalamazoonesis, and Pseudomonas cellulosum in the rhizosphere that are reported here for the first time in agricultural literature. Pathway prediction analysis using KEGG (Kyoto Encyclopedia for Genes and Genomes) and COG (clusters of orthologous genes) databases identified metabolic pathways associated with biocontrol properties against pathogens. We confirmed the metagenome data in vitro, which demonstrated their PGP potential and antimicrobial properties. For instance, S. indicus produced high concentration of indole-3-acetic acid, a PGP phytohormone, that can stimulate plant growth. In addition, an antimicrobial susceptibility assay suggested that bacterial extracts displayed activity against Xanthomonas, a primary pathogen causing the pomegranate wilt disease. In conclusion, this study suggests that S. indicus, B. kalamazoonesis, and P. cellulosum can potentially be PGP and biocontrol agents that may contribute to increased crop productivity in pomegranate cultivation. These agents and their combinations warrant future research with an eye on SDGs and so as to enable and innovate organic farming and pomegranate agricultural practices. [ABSTRACT FROM AUTHOR]

The prevalence of anemia in India is worrisome; the Government is aiming to reduce the prevalence of anemia among women at adolescent and child bearing age. A Public Health Initiative was undertaken to mainstream the use of Siddha drugs to combat anemia among the adolescent girls of Virudhunagar district, Tamil Nadu, India. With the assistance from the Siddha physicians in Primary Health Centers and Government hospitals, adolescent girls with anemia were identified. After obtaining informed consent, the girls with anemia received a Siddha treatment regimen (Aṉṉapēti centūram, Bāvaṉa kaṭukkāy, Mātuḷai maṇappāku and Nellikkāy lēkiyam; ABMN) for 45 days. Deworming was done with Cuṇṭaivaṟṟal cūraṇam before the start of the treatment. The clinical and biochemical features were studied before and after ABMN treatment. Through this program, 14,179 adolescent girls were screened for anemia and 3,783 girls were found anemic; out of them 2,300 (86.85%) girls completed the 45 days program. Marked reduction of various clinical features of anemia was found with ABMN treatment. ABMN treatment improved the hemoglobin content by 24.30% (N=155), 15.96% (N=1440) and 4.29% (p=0.0005; N=705) in severe, moderate and mild anemic girls, respectively. Long term, multicentric investigations are needed to conclude the efficacy and safety of ABMN for treating iron deficiency anemia. [ABSTRACT FROM AUTHOR]

A novel approach known as seed priming has been developed to improve seed germination and, ultimately, increase growth and yield. For high-value crops like pomegranates (Punica granatum) in high-altitude regions like the Taif area, affordable, sustainable, and efficient seed treatments are yet to be discovered. In this study, we employed a green synthesis method using pomegranate peel and coffee ground extracts to synthesize silver nanoparticles (AgNPs) at a concentration of 80 mg/mL. These AgNPs were then utilized to prime pomegranate seeds for 24 h. Furthermore, a chemical reduction method using trisodium citrate was used for comparison. The adsorption of NPs was verified using scanning electron microscopy (SEM) and energy dispersive X-ray (EDX), while their incorporation was confirmed by transmission electron microscopy (TEM). We further validated our EM results with X-ray fluorescence (XRF) and inductively coupled plasma–optical emission spectroscopy (ICP-OES). According to the findings of this study, AgNPs were observed to be present within seeds even after undergoing storage during priming. There is a possibility that the results obtained could potentially contribute to maintaining the quality of crops in a sustainable and eco-friendly manner. [ABSTRACT FROM AUTHOR]

Punica granatum peel is a significant source of polyphenolic compounds that have potential uses as drugs. This study aimed to obtain and purify polyphenolic compounds derived from pomegranate peel and to evaluate their potential anticancer activity in cell lines. Polyphenols from the pomegranate peel were extracted using hybrid ultrasound‐microwave technology. Different mass:volume ratios and water:ethanol ratios were used during extraction. Purification was performed on a chromatographic column with Amberlite XAD‐16, and unfractionated extracts and fractions extracts were obtained. The main compounds identified by HPLC belong to the ellagitannins family. The unfractionated extract from the 1:12 (m/v) and 30% ethanol condition was used to evaluate its cytotoxic effect against HeLa, HepG2, and 3T3 cell lines. The MTT assay was used to evaluate the cytotoxicity of the pomegranate polyphenolic extracts (PPEs). Viability in HeLa and HepG2 cells was affected in a dose‐dependent manner by a concentration of 25 ppm of polyphenol powders. Additionally, a genotoxicity test was carried out, which showed DNA damage, indicating that the cytotoxic effect is possibly due in part to DNA damage. The use of the pomegranate peel could be a viable option for obtaining bioactive compounds that can be used as adjuvants or in the treatment of various diseases such as cancer.

Fruit cracking and sunburn are two major disorders that can negatively impact pomegranate (Punica granatum L.) production. To address these problems, an experiment was conducted to evaluate the combined effects of silica (0, 100, 300, and 500 ppm) and calcium nitrate (0, 0.75%, and 1.5%) spraying on the fruit of 'Malase-Saveh' pomegranate. The treatments were applied three times during the growing season and a factorial experiment was conducted based on the completely randomized block design. The results indicate that most of the qualitative and quantitative traits were influenced by foliar spraying of these substances. Furthermore, the results demonstrated that foliar application of silica, calcium nitrate, and their interaction significantly affected fruit cracking. The lowest fruit cracking (1.06%) was obtained by spraying 500 ppm silica and 1.5% calcium nitrate, while the highest fruit cracking (21.6%) was recorded from untreated plants. The highest fruit weight (215.4 g) was observed in the treatment 1.5% calcium nitrate. Most of the treatments had a positive effect on fruit weight and increased it compared to the control. Moreover, the treatments improved some qualitative characteristics, such as an increase in fruit acidity and decrease in sunburn disorder. Ultimately, this study concluded that combined spraying of silica with calcium is more effective than individual use and results in the highest fruit yield and quality, as well as the lowest cracking and sunburn disorders. These findings suggest there are synergistic effects between these compounds. [ABSTRACT FROM AUTHOR]

Pomegranate, celebrated for its rich cultural heritage in the Middle East and its abundant polyphenols, holds promise as a potent dietary supplement. Beyond its traditional use, pomegranate supplementation has gained attention for its potential to alleviate physiological stressors and enhance overall health. However, its impact on exercise performance and recovery remains a subject of debate, marked by conflicting study outcomes. This comprehensive study investigates the effects of pomegranate supplementation on various physiological parameters in sportsmen, athletes, and healthy individuals. Adhering to Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines, a meticulous literature review encompassed multiple databases, yielding 4401 articles. From these, 23 studies involving 507 participants met stringent inclusion criteria, showcasing a broad spectrum of pomegranate dosages and methodologies. Findings suggest that pomegranate supplementation may significantly benefit health markers and exercise performance. Meta-analysis underscored notable improvements in markers such as aspartate transaminase (AST), high density lipoprotein (HDL), malondialdehyde (MDA), lactate, systolic blood pressure (SBP), and diastolic blood pressure (DBP) between pomegranate and placebo groups. Most of the studies suggested using 250 ml of pomegranate juice daily for at least one week to get its beneficial effects. Notably, enhancements in antioxidant status and cardiovascular health hint at potential advantages for exercise-related outcomes, including accelerated muscle recovery, reduced soreness, and enhanced endurance during prolonged sessions. In conclusion, pomegranate emerges as a compelling natural alternative to synthetic supplements for athletes and sports enthusiasts aiming to optimize physical performance and overall well-being. Nonetheless, further exploration is essential to unravel its mechanisms fully, urging standardized protocols and larger-scale studies to validate and refine these promising findings.

The sustained higher profitability of a pomegranate orchard relies heavily on the production of a greater proportion of high-quality fruits, a goal achievable through the implementation of effective management practices. The objective of this study is to provide site-specific supplementary knowledge regarding the response of pomegranate plants to various management practices under arid conditions. With the aim of enhancing both marketable fruit yield and quality of pomegranate in arid regions, four separate and simultaneous experiments were conducted in the same orchard to evaluate (i) the response of planting materials derived from tissue culture, air layering, and cutting; (ii) the impact of crop (fruit) load; (iii) the response of crop regulation; and (iv) the application response of organo-mineral fertilizers containing potassium (OMF-K) and phosphorus (OMF-P). The results obtained for plant growth, fruit yield, and fruit quality did not exhibit significant differences among pomegranate plants raised through the three different methods of vegetative propagation. Striking results in terms of producing superior-grade fruits, higher marketable yield, and overall fruit quality were achieved with crop loads of 80 fruits per plant. Staggering the crop regulation from June to September effectively extended the harvesting season to four months, from the last week of November to March, with eventual benefit of reduced fruit cracking compared to the standard two-month harvesting period obtained from normal regulation. Soil application of the indigenously developed OMF-K in two equal splits, along with the recommended N and P through inorganic sources, significantly reduced fruit cracking (only 6.23%) compared to the recommended NPK through inorganic sources (26.9%), while maintaining similar physicochemical quality attributes.

IntroductionMedicinal plants like Punica granatum (pomegranate) have traditional uses against diabetes, inflammation and other diseases. The study was initiated to get an insight into the interaction tendency of P. granatum derived compounds with diabetes associated human thioredoxin-interacting protein (TXNIP). High glucose in diabetes induces production of TXNIP resulting in β-cells apoptosis. Its inhibition might reduce the diabetes incidence.MethodsTo elucidate the therapeutic potential of P. granatum peel against diabetes through GC-MS based identification of extracted compounds followed by application of computational algorithms. P. granatum peel extracts were screened for antioxidant, anti-inflammatory, anti-diabetic, antimicrobial and wound healing properties. Phytochemical and GC-MS based analysis were performed to identify the bioactive compounds. Molecular docking analysis was performed by Auto Dock Vina to predict the binding tendency of P. granatum derived compounds with TXNIP.Results and DiscussionThe peel exhibited antioxidant, anti-inflammatory and anti-diabetic activities, which were attributed to phytochemicals like phenols, tannins and steroids. GC-MS analysis identified 3,5-octadien-2-one, 1H-pyrrole -2,5-dione, Beta-D-lyxofuranoside, 5-O-(beta-D-lyxofuranosyl)-decyl, diethyl phthalate, 9-octadecenoic acid (Z)-, methyl ester, hexadecanoic acid, methyl ester, n-hexadecanoic acid, tetradecane, 2,6,10-trimethyl, bis (2-ethylhexyl) phthalate, decane, 3,8-dimethyl, 9-octadecenoic acid (Z)-, methyl ester and bis (2-ethylhexyl) phthalate in P. granatum peel extracts. Docking analysis revealed high binding affinities of bis (2-ethylhexyl) phthalate and 9-octadecenoic acid with TXNIP i.e., –4.5 and –5.0 kcal/mol, respectively, reflecting these compounds as potent antidiabetic agents. This study validates the traditional uses of P. granatum peel and demonstrates how computational approaches can uncover pharmacologically active phytochemicals. The results suggest P. granatum peel is a promising source of novel therapeutics against diabetes, inflammation, and oxidation. Further studies on the optimization of identified ligands are warranted.

The construction industry widely uses TMT bars. However, its corrosion is a major challenge for civil engineers. Green corrosion inhibitors in place of inorganic inhibitors are one of the effective ways to prevent the corrosion which results sustainable solution. Researchers have not explored the corrosion mitigation of TMT bars with Punica granatum. Its peel (agro-waste) as a green inhibitor for TMT bars in powder/extract form exposed to 1M HCl was investigated through gravimetric and electrochemical studies using TMT bars of 8 mm diameter, 30mm, and 5 mm length respectively. The experimental work used five different concentrations of peel powder, ranging from 3.5 g to 17.5 g, and peel extract from 15 ml to 75 ml. The corrosion analysis yielded a maximum inhibition efficiency of 86.64% for powder and 83.32% for extract. Qualitative screening identified the presence of phytochemicals. The UV-Vis and FTIR spectra before and after corrosion define the chemisorption process, confirming the formation of protective layers on the bars. Steel admixed with inhibitor showed a smooth surface with fewer cracks/pits after corrosion through AFM and FE-SEM. The weight loss results were modeled using the response surface method and obtained R2 as 0.9016 (powder) and 0.9001 (extract).

AbstractStudies on the potential applications of nanoparticles (NPs) synthesized by biological methods attract the attention of researchers. First time in this study, photocatalytic activities of NiFe2O4 NPs synthesized with pomegranate fruit peel extract were determined against brilliant blue. Surface charge and dynamic size of NPs were detected at −11 mV, and 405 nm, respectively. According to scanning electron microscopy images, NiFe2O4 NPs have spherical morphology with a diameter of 75 nm. Energy dispersive X-ray spectroscopy, X-ray diffraction, and Fourier transform infrared spectroscopy were used for the determination of elemental composition, crystallinity, and functional groups of NPs, respectively. As a result, it was determined that NiFe2O4 NPs were effective for remediation (65%, for 3 h) of dye. The catalytic activity of NiFe2O4 NPs refers to the Fenton mechanism. [ABSTRACT FROM AUTHOR]

The pomegranate (Punica granatum L.) market has steadily grown due to the increasing demand of health-conscious consumers of products with health-promoting effects. Recently, a growing interest in developing ecological and environmentally friendly extraction methods has led to investigating extraction procedures to obtain a higher extraction yield using a lower amount of solvents and energy. Herein, a new extraction procedure was developed to obtain an enriched pomegranate food supplement by using the peels of pomegranate, cultivar "Dente di Cavallo" and its juice. The extraction was performed through a non-conventional extraction technique like SLDE-Naviglio using ethanol and pomegranate juice as a solvent, and peels as a matrix. The extract was analysed by a combined approach based on LCESI/QExactive/MS/MS and NMR analysis, and its chemical profile was compared with those of pomegranate juice and of the extract obtained from peels by SLDE-Naviglio by using ethanol:H2O. The LC-MS analysis highlighted the presence of hydrolysable tannins, flavonoids, ellagic acid and phenol glucoside derivatives, while 1H NMR analysis completed the profile by detecting the primary metabolites. The LC-MS and 1H NMR analysis indicated that the extract obtained by SLDE-Naviglio using ethanol and pomegranate juice was enriched in the bioactives as confirmed by the highest phenolic, tannin and flavonoid content.

Fruit consumption guarantees the supply of most of the necessary nutrients for a complete and balanced diet, as it is a relevant source of vitamins, minerals, and antioxidants. In particular, pomegranate has very interesting medicinal properties, such as an anti-inflammatory effect and the protection of the cardiovascular system, among others. During pomegranate juice production, it appears cloudy and must be clarified to remove suspended solids such as colloids and high-molecular weight tannins. The membrane clarification process is a cost-effective alternative to the conventional methods, resulting in a high-quality product. In this work, the clarification of pomegranate juice using the Triple System Model F1 membrane module was carried out for the Mollar and Wonderful varieties with early and late maturity. Three ultrafiltration membranes with different molecular weight cut-off and different chemical compositions were used. The rejection coefficient and permeate flux (which represent the selectivity of the membranes and the process efficiency, respectively) were measured. GR-40PP showed the best results in terms of membrane selectivity and process efficiency, achieving adequate physicochemical juice parameters. Regarding the comparison of the maturity degree, in general terms, the Mollar variety showed better results. Ripe pomegranates showed greater selectivity, while the process efficiency was higher for the early samples. [ABSTRACT FROM AUTHOR]

The paper is focused on examining and selecting morphometric indicators of leaves and flowers from genotypes within the collection of the pomegranate varieties. The research was carried out on 6 varieties of pomegranate plants, collected and introduced from diverse ecological and geographical regions. The objective was to collect, cultivate and assess the technological features of pomegranate varieties and forms. The morphometric characteristics of generative and vegetative organs from the “Malas” and “Kirmizi Gazyan” varieties were studied for the first time. Observation of pomegranate flower petals revealed that different sizes could be found in both long toothed (LT), middle toothed (MT) and short-toothed (ShT) flowers, suggesting petal size is not determined by flower type. The difference between the leaves of these two varieties was found to be insignificant. Flower diameter showed variability across all three types of flowers. The biological and economic significance of the newly developed form F-6-8 and the varieties “Malta”, “Oleg” and “Devachi” was also assessed. “F-6-8” and “Malta” are sweet varieties, while “Oleg” and “Devachi” are sweet and sour varieties. “Malta” was distinguished by its fruit weight (380.4 g), thin skin (2.5 g) and high juice yield (50.4%).

The aim of this review is to provide a summary of the botany, phytochemistry and dermatological effects of Punica granatum (PG), with special emphasis on therapeutic mechanisms in various skin conditions. PG peel contains the highest levels of chemical compounds. Due to the high abundance of polyphenolic compounds, including phenolic acids, anthocyanins and flavonoids, exhibiting strong antioxidant properties, PG peel possesses significant health-promoting effects. Up until now, different parts of PG in the form of various extracts, fixed seed oil or individual active compounds have been investigated for various effects on skin conditions in in vitro and in vivo studies, such as antioxidant, anti-inflammatory, antimicrobial, chemoprotective and antiaging effects, as well as positive effects on striae distensae, skin repair mechanisms, erythema, pigmentation and psoriasis. Therefore, formulations containing PG active compounds have been used for skincare of diseased and healthy skin. Only a few effects have been confirmed on human subjects. Based on encouraging results obtained in in vitro and animal studies about the numerous substantial dermatological effects of PG active compounds, future perspectives should incorporate more in vivo investigations in human volunteers. This approach can aid in identifying the optimal concentrations and formulations that would be most efficacious in addressing specific skin conditions. [ABSTRACT FROM AUTHOR]

Pomegranates are grown in upper Egypt, especially in Assiut Governorate, for fresh consumption and juice. Due to increased awareness of pomegranate's health advantages, there is an exponential increase in demand for pomegranate fruit and its by-products. In order to determine the impact of four levels of potassium citrate (100, 200, 300, and 400 ppm) on yield and fruit quality, this study was conducted during the 2021 and 2022 growing seasons on 45 years-old Manfalouty and Hajazy pomegranate trees in the Pomology Orchard at the Faculty of Agriculture, Assiut University. A factorial experiment with three replicates was conducted randomized complete blocked design (RCBD). The results showed that potassium citrate treatment led to significant differences at four concentrations used and the concentration of 200 ppm was the best in increasing leaf area, fruit weight, arils and rind weight, juice volume, total soluble solids (TSS), TSS / total acidity, reducing sugars, while there was a significant decrease in total acidity percentage.

Pomegranate (Punica granatum L.) is very important in terms of horticulture and food in the world. In total, 125 pomegranate genotypes were selected from the Saveh region in Markazi province, Iran, to determine morphological variation and also to select the promising genotypes based on the quality of fruit. The measured traits showed significant variation among these genotypes. Fruit length ranged from 46.22 to 93.04 mm, and the range of fruit diameter was from 48.42 to 108.69 mm. The range of fruit weight was from 77.23 to 511.11 g, and 100-aril fresh weight ranged between 15.65 and 48.23 g. Principal component analysis placed the traits into seven components explaining 78.41% of the total variation. The first principal component showed significant correlations with fruit diameter, fruit length, fruit neck diameter, fruit crown diameter, peel thickness, and fruit weight, called fruit size components which had the greatest effect on the separation of genotypes. Ward dendrogram and scatter plot showed considerable variations in the 125 genotypes with several groups. In conclusion, one soft-seeded genotype and 21 semi-soft-seeded genotypes were selected that may be used by the breeding programs. Also, among the above 22 genotypes, 10 genotypes with high fruit quality traits, such as fruit weight, aril weight, aril color, and TSS, are recommended for cultivation in commercial orchards.

The pathogenicity of the bacteria was confirmed through laboratory tests and molecular identification. This finding is significant for growers as it provides valuable information for disease control measures. [Extracted from the article]

Background: Hypercholesterolemia, characterized by elevated low-density lipoprotein (LDL) cholesterol levels, is a significant risk factor for cardiovascular diseases. Familial and behavioral factors contribute to its onset, and while lifestyle changes offer some benefits, medical interventions are essential to manage this condition effectively. Statins, the primary medications used to lower LDL cholesterol, have limitations, including the unintended upregulation of proprotein convertase subtilisin/kexin type 9 (PCSK9). Therefore, exploring alternative approaches to enhance LDL receptor expression while targeting PCSK9 is crucial, with herbal medicine showing promise in this endeavor. Objective: This study investigates the potential of pomegranate peel extract and punicalagin, a key pomegranate component, in lowering LDL cholesterol in HepG2 cells. The research explores their effects on LDL receptor (LDLR) expression, LDL uptake, and proprotein convertase subtilisin/kexin type 9 (PCSK9) gene expression. Methods: HepG2 cells were treated with different concentrations of pomegranate peel extract (37.5, 75, 150, and 300 µg/ml) and punicalagin (12.5, 25, 50, and 100 µg/ml). Next, the viability of HepG2 cells, the protein levels of LDL receptors and LDL uptake, and the expression levels of PCSK9 were measured. Results: Pomegranate peel extract (37.5, 75, 150, and 300 µg/ml) and punicalagin (12.5, 25, 50, and 100 µg/ml) did not exhibit significant cytotoxicity and significantly increased LDLR protein levels (P-value= 0.00, after 24 hours) and LDL cholesterol uptake (P-value= 0.00, after 24 hours). Furthermore, they exhibited a dose-dependent reduction in the expression of PCSK9 (pomegranate: P-value= 0.01; punicalagin: P-value= 0.00). Conclusion: These findings suggest that pomegranate peel extract and punicalagin have the potential to serve as effective agents in managing hypercholesterolemia by enhancing LDL receptor expression and reducing PCSK9 expression in HepG2 cells. Further research is required to explore their effects on transcription factors and PCSK9 function. [ABSTRACT FROM AUTHOR]

Production sustainability is affected by climate change and land destruction, which exacerbates the challenge of food security. In addition to ensuring food security, fortification of products is a potential approach to enhance their nutritional quality and safety. Climate change has a significant effect on pre-harvest physiology. Water and soil salinity reduce the yield and quality of products. On the other hand, long-term drought stress reduces the supply of nutrients and cracks the pomegranate fruit. Therefore, it increases susceptibility to fungal diseases, which reduces commercial value. Pre-harvest factors significantly affect post-harvest physiology and quality characteristics related to storage life. Therefore, it is necessary to use efficient and cost-effective strategies to resist environmental stress and enhance yield. Meanwhile, the management of nutrients and plant growth regulators (PGRs) plays an essential role in plant resistance against abiotic stresses and determines their distribution and survival. Therefore, proper management practices are necessary for sustainable production. This paper reviewed and discussed recent advances regarding the foliar application of important nutrients, and PGRs, which increase the yield and quality of pomegranate fruit. In conclusion, foliar application of fertilizers, nanofertilizers, and nanoparticles include Fe, Zn, Ca, K, Br, Se and some PGRs such as salicylic acid and gibberellic acid, and kaolin can be used to increase yield, improve nutritional quality, reduce disorders and also decrease postharvest losses of pomegranate fruit during storage. However, further research in various commercial pomegranate cultivars is necessary to recommend for practical application at harvest and after cold storage of pomegranate fruit.

Prolonged use of Highly Active Antiretroviral Therapy (HAART) has been linked to toxicity, particularly hepatotoxicity. There are few effective drugs for HAART patients that promote hepatic cell regeneration and prevent liver injury. Therefore, the purpose of this study was to investigate the hepato-protective activity of Methanol fruit extract of Punica granatum (MFEPG) in HAART-administered rats. Thirty rats weighing between 150–200 g were randomly divided into six groups and each group comprised of five rats. Distilled water was given to the rats in group one. Only HAART was given to the rats in group two. MFEPG at doses of 100 and 400 mg/kg was given to the rats in groups three and four. MFEPG dosages of 100 and 400 mg/kg along with HAART were given to the rats in groups five and six, respectively. All treatments were via oral gavage daily for 40 days. Under halothane anesthesia, all rats were sacrificed on day 41. Liver tissues were utilized for lipid peroxidation marker; Malondialdehyde (MDA), antioxidant enzymes; Superoxide dismutase (SOD) and Catalase (CAT) and histological evaluation, while blood samples were examined for biochemical parameters (AST, ALT, ALP, Total cholesterol, Total protein, and Albumin). The HAART-treated group exhibited a significantly higher amount of the lipid peroxidation end product; MDA, and significantly lower levels of antioxidant enzymes; SOD, and CAT. Liver enzymes and total cholesterol were significantly increased with a significant reduction in Total protein and Albumin levels in the HAART-treated group. Conversely, the liver function biomarkers were returned to normal levels in the HAART and MFEPG-treated groups. Histopathological studies revealed that when HAART-exposed rats were treated with MFEPG, both the biochemical and histological results significantly improved. Thus, the antioxidant activity of MFEPG provides protection against HAART-induced liver oxidative damage. More research is needed to determine the safety of using MFEPG in humans.

In the present study, the oxidative stability and antioxidant activity of seed oils were investigated in three Iranian pomegranate cultivars, Shirin Khafr, Torsh Sabz, and Rabab, along with the sesame (Sesamum indicume L. cv Dezful) seed oil. Punicic acid was the primary fatty acid in the pomegranate seed oils, with contents ranging from 75.5 to 80.9% (w/w). The tocopherol levels in pomegranate seed oils ranged from 1439 to 2053 mg/kg, whereas the phenolics ranged from 130 to 199.3 mg/kg, respectively. Comparatively, in the seed oil of sesame "Dezful," these substances' contents were 1053 and 79 mg/kg, respectively. Contrary to common perception, the seed oil of the three pomegranate cultivars cultivated in Iran had high oxidative stability and antioxidative activity during the 32 h of thermal processing at 170°C. The oxidation stability assayed by peroxide value, p‐anisidine value, and TOTOX index revealed that the pomegranate seed oils had a much higher resistance to the oxidation process than the sesame oil. The content of tocopherols increased during thermal processing due to the regeneration phenomenon. Tocopherols are not always free and may form a matrix with themselves or other compounds. Changes in the antioxidant activity during the thermal processing assessed by DPPH free radical scavenging power and by the FRAP test were consistent with those for the antioxidants. Therefore, these oils can be added to other edible oils as a natural antioxidant to improve their oxidative stability. [ABSTRACT FROM AUTHOR]

The Punica granatum (Pomegranate) tree attracted a lot of interest for its nutritious fruits and therapeutic benefits. Although research on genetic diversity is important to develop breeding programs and implement efficient cultivar improvement, the genetic diversity of pomegranates in Saudi Arabia has not been investigated completely. The two important pomegranate cultivars in Al-Baha region of Saudi Arabia (Bidah-red and Bidah-green), which have recently gained considerable attention due to their unique sweet taste, were studied using DNA barcodes because information about their phylogeny is limited. To reveal the phylogeny of these two cultivars, three DNA barcodes [the internal transcribed spacer 2 (ITS2), ribulose 1,5-biphosphate carboxylase (rbcL), and intergenic spacer region (trnH-psbA)] were used. The ITS2 and psbA-trnH had sufficient polymorphism to allow distinction at the cultivar level, whereas the rbcL region had a uniform sequence; hence, it failed to discriminate among the cultivars. The two cultivars were found to be clustered in the same clade on the phylogenetic tree constructed using the ITS2 and psbA-trnH sequences, suggesting that they are either closely related or have adapted to their locations. As the ITS2 region exhibited higher polymorphism than psbA-trnH, the phylogenetic tree based on ITS2 indicated that Bidah-red and Bidah-green are distinct cultivars. We conclude that ITS2 and psbA-trnH DNA barcodes are capable of authenticating and identifying pomegranate cultivars and can assist in improving pomegranate quality in the future through molecular breeding.
