Objective: Moringa oleifera Lam. (Moringaceae), has traditionally been used for various renal diseases including urolithiasis. Considering the therapeutic and nutritional values, the present study was designed to investigate the antiurolithiatic potential of M. oleifera leaves through in-vitro , in-silico and in-vivo approaches. Methods: Methanolic aqueous extract of M. oleifera . leaves (MoL.Cr) was prepared and screened for phytoconstituents through FTIR and HPLC analysis, while antioxidant potential was determined by DPPH assay. Crystal nucleation, aggregation and growth assays were carried out to ascertain the in-vitro inhibitory effects of MoL.Cr. Molecular docking was performed to analyze the interactions between phytoconstituents and targeted proteins (Glycolate oxidase, Albumin and Tamm-Horsfall). Whereas, ethylene glycol-induced urolithiasis model (1% ammonium chloride +0.75% ethylene glycol) was used for in-vivo study. Presence of alkaloids, phenols, glycosides and flavonoids was confirmed by FTIR and HPLC analysis. Results: MoL.Cr significantly inhibited the CaOx crystal nucleation, aggregation as well as growth and normalized urinary and serum parameters. Histological studies showed that MoL.Cr significantly restored hyperoxaluria-induced irregular epithelial lining, interstitial inflammation and dilated proximal tubules. Conclusions: Thus, M. oleifera demonstrated marked stone inhibiting potential which can be due to its antioxidant, lowering of urinary concentration of stone forming constituents and anti-crystallization effects.

The study was designed to investigate the pharmacological potential of 70%methanolic extract of Vigna mungo for the management of hyperthyroidism and estrus cycle disturbances in female rats. The preliminary phytochemical analysis of the extract was performed. Hyperthyroidism was induced by administering levothyroxine (600 µg/kg; orally) for 14 days. Phytochemical analysis of the extract showed the presence of alkaloids, flavonoids, phenols, saponins, fats, and oils. The extract (300, 500, and 1,000 mg/kg; orally) and carbimazole (30 mg/kg; orally) were administered individually for the next 14 days. The extract showed dose-dependent antithyroid potential, as evidenced by the decrease in T3 and T4, and the increase in TSH levels. Body weight, body temperature, fasting blood glucose levels, and prolonged diestrus phase were reversed towards normal and significant effects on the morphology of the thyroid gland and ovary of the rats were observed. Therefore, the findings reveal that V. mungo has the potential to treat experimentally-induced hyperthyroidism and estrus cycle disturbances.

Abstract In this research work, Bi2O3, Bi2O3/GO and Bi2O3/CuO/GO nanocomposites have been synthesized via an eco-friendly green synthesis technique, solgel route and co-precipitation method respectively for the assessment of antibacterial activity as well as in vivo toxicity. The XRD patterns confirm the formation of Bi2O3, Bi2O3/GO and Bi2O3/CuO/GO nanocomposites showing monoclinic structures. Crystallite size and lattice strain are calculated by Scherrer equation, Scherrer plot and Willimson Hall plot methods. Average crystallite size measured for Bi2O3, Bi2O3/GO and Bi2O3/CuO/GO nanocomposites by Scherrer equation, Scherrer plot and WH-plot methods are (5.1, 13.9, 11.5)nm, (5.4, 14.2, 11.3)nm and (5.2, 13.5, 12.0)nm respectively. Optical properties such as absorption peaks and band-gap energies are studied by UV–vis spectroscopy. The FTIR peaks at 513 cm−1, 553 cm−1 and 855 cm−1 confirms the successful synthesis of Bi2O3, Bi2O3/GO and Bi2O3/CuO/GO nanocomposites. The antibacterial activity of synthesized Bi2O3, Bi2O3/GO and Bi2O3/CuO/GO nanocomposites is examined against two gram-negative (Escherichia coli and pseudomonas) as well as gram-positive bacteria (Bacillus cereus and Staphylococcus aureus) at dose 25 mg/kg and 40 mg/kg by disk diffusion technique. Zone of inhibition for Bi2O3, Bi2O3/GO and Bi2O3/CuO/GO at dose 40 mg/kg against E. coli (gram − ve) are 12 mm, 17 mm and 18 mm respectively and against Pseudomonas (gram − ve) are 28 mm, 19 mm and 21 mm respectively. While the zone of inhibition for Bi2O3/GO and Bi2O3/CuO/GO at dose 40 mg/kg against B. cereus (gram + ve) are 8 mm and 8.5 mm respectively and against S. aureus (gram + ve) are 5 mm and 10.5 mm respectively. These amazing results reveal that Bi2O3, Bi2O3/GO and Bi2O3/CuO/GO nanocomposite as a kind of antibacterial content, have enormous potential for biomedical applications. In addition, the in vivo toxicity of synthesized Bi2O3/CuO/GO nanocomposite is investigated on Swiss Albino mice at dose of 20 mg/kg by evaluating immune response, hematology and biochemistry at the time period of 2, 7, 14 and 30 days. No severe damage is observed in mice during whole treatment. The p value calculated by statistical analysis of hematological and biochemistry tests is nonsignificant which ensures that synthesized nanocomposites are safe and non-toxic as they do not affect mice significantly. This study proves that Bi2O3/CuO/GO nanocomposites are biocompatible and can be explored further for different biomedical applications.

Portulacaria afra Jacq (Portulacaceae) is a medicinal plant used traditionally in the treatment of pain and inflammation. This study aimed to evaluate the phytochemical composition, toxicity, antinociceptive, and enzyme inhibition potential of P. afra. The methanol extract (PAME) was prepared through maceration and fractionated with ethanol to ethanol fraction of P. afra (ETPA). Both PAME and ETPA were found to be rich in total phenolic (TPC) and total flavonoid contents (TFC). Similarly, PAME showed the highest antioxidant potential through ABTS 93.16 ± 0.05 mg TE /g of dry extract (D.E.) while ETPA showed maximum results (462 ± 1.44 mg TE/g) in the CUPRAC method. The RP-UHPLC-MS analysis of PAME showed tentative identification of 101 compounds in the positive mode and 14 compounds in the negative mode of ionization while GC–MS profiling gave a total of 15 compounds. The acute oral toxicity study of PAME revealed the safety and biocompatibility of the extract up to a dose of 5000 mg/kg orally in rats. In-vitro data revealed that varying concentrations of P. afra significantly (p

Neurada procumbens Linn. possesses a wide range of phytochemical and bioactive entities such as flavonoids and polyphenols that decrease the oxidative stress and enhance synaptic plasticity, resulting in accelerated healing processes. Almost all parts of the plant have been used in the traditional system of medicine for various disorders including its use as an anticonvulsant, sexual tonic, and anti-rheumatic agent. This study is designed to evaluate the anxiolytic and antidepressant activities of the methanolic crude extract of N. procumbens (Np.Cr) based on its use in traditional medicine and presence of the phytochemical constituents. Aqueous methanolic extract of Np.Cr was prepared under reduced pressure using rotary evaporator, and different chemical constituents were identified by phytochemical screening. Light/dark exploration, elevated plus maze (EPM), and hole board tests were used to assess the anxiolytic activity, while forced swim and tail suspension tests were used to assess the antidepressant potential of the crude extract. Treatment groups treated individually with 3 different doses; i.e., 50, 100, and 200 mg/kg of Np.Cr, showed a dose-dependent increase in time spent in light compartment and in open arms as well as increased number of head poking by the experimental animals. Np.Cr showed significant antidepressant potential ( P < .05) as evident from marked decrease in behavioral despair. Findings of the present study assure that N. procumbens possess significant anxiolytic and antidepressant potential with the demands of further investigations to identify the active compound(s) responsible for these pharmacological effects.

Obesity, a chronic metabolic condition, is an increase in fat mass and blood lipid levels mainly causing atherosclerosis and hypertension, which further lead to cardiovascular complications. The objective of the study was to investigate the crude extract of Caralluma edulis (CE.Cr) for its potential against high-fat diet (HFD)-induced obesity and its related complications. Hyperlipidemia was induced in Wistar albino rats with HFD (1% cholesterol + 0.5% cholic acid) for 28 days. Treatment groups were administered with different doses of CE.Cr (100, 300 and 500 mg/Kg, p.o.) and the standard group received atorvastatin. At the end of study, sera were analyzed for biochemical markers and the aorta was dissected for microscopic examination. Antioxidant potential was evaluated and high-performance liquid chromatography (HPLC) analysis was performed. The hypotensive potential of CE.Cr was evaluated through an invasive technique. HPLC analysis of CE.Cr showed the presence of chlorogenic acid, caffeic acid, apigenin and naringenin. Histological examination of the aorta section showed anti-atherosclerotic effects which were also evident from decrease in serum total cholesterol, triglycerides and low-density lipoproteins levels. CE.Cr decreased mean arterial blood pressure and evoked significant hypotensive effects. The crude extract of C. edulis showed anti-obesity, antihypertensive, anti-atherosclerotic and antioxidant potential.

Background Thrombosis is a major disorder which is an outcome of an imbalance in the hemostatic system that develop undesirable blood clot and hinder blood circulation. Purpose The current study was designed to verify the potential of aqueous methanolic crude extract of Asphodelus tenuifolius Cav . (At.Cr), used traditionally as remedy in circulatory problems. Research Design Antioxidant activity, FTIR, and HPLC analysis were performed. In-vitro clot lysis assay was performed on human blood samples, and in-vivo acute pulmonary thromboembolism model was developed by administering the mixture of collagen and epinephrine in tail vein of mice.

Geranium wallichianum D. Don ex sweet traditionally been used as home remedy for backaches, joint pain, colic, and rheumatism. The objective of this study was to investigate the therapeutic benefits of plant in an adjuvant-induced arthritis paradigm. Immune-mediated rheumatoid arthritis was developed by injecting complete Freund’s adjuvant (CFA) into the hind paws of rats and the aqueous methanolic crude extract was administered. The animals were physically monitored for changes in paw edema size and arthritic score. Hematological parameters and systemic inflammatory indicators evaluated. Genetic expressions of tumor necrosis factor (TNF-α), interleukins (IL-1β, IL-6), necrosis factor (NF-κB), and cyclooxygenase (COX-II) enzyme were studied using real-time qPCR. PGE2 levels in blood were quantified through Enzyme Linked Immunosorbent Assay (ELISA). On the 14th day, Immunoglobulin E (IGE) exhibited a substantial decline in paw edema and arthritic score. At the doses of 500 mg/Kg ( P ≤ .05) and 1000 mg/Kg ( P ≤ .001), IGE significantly reduced TNF-α, interleukins, and COX-II mRNA expression. IGE significantly lowered the MDA levels at the doses of 500 and 1000 mg/Kg (13.18 ± .70 and 9.04 ± .26 μM/L respectively) as compared to arthritic control (30.82 ± 1.12 μM/L) group. IGE significantly improved the antioxidant enzyme activities of CAT and SOD ( P ≤ .001) in treated animals. TNF-α, interleukins, and COX-II mRNA expression were also significantly reduced at the doses of 300 ( P ≤ .05), 500 ( P ≤ .01) and 1000 mg/Kg ( P ≤ .001) which were expressed as fold changes. This study shows that Geranium wallichianum D. Don ex sweet has a strong potential to alleviate immune-mediated arthritis by lowering oxidative stress and downregulating the proinflammatory cytokines signaling mechanisms.

The study was designed to investigate the antithyroid activity of the crude methanolic (70%) extract of aerial parts of Abutilon indicum in male albino rats. The extract was prepared and analyzed for the presence of phytochemical constituents through preliminary chemical analysis, antioxidant assay and GC-MS. The in vivo antithyroid activities in thyroxine-induced hyperthyroidism were studied. Phytochemical analysis showed the presence of alkaloids, flavonoids and phenols, also verified by the data obtained from GC-MS. Thyroxine increased the levels of triiodothyronine (4.9 ± 0.1 ng/mL) and total thyroxine (9.4 ± 0.2 μg/dL); while, A. indicum at the doses of 300 and 500 mg/kg, showed significant decrease in the elevated levels of triiodothyronine (3.0 ± 0.1 and 2.6 ± 0.2 ng/mL) and thyroxine (7.7 ± 0.2 and 7.1 ± 0.2 μg/dL), respectively. Histopathological studies showed the restoration of filled follicular colloids in extract-treated animals. The results show that A. indicum exhibits dose-dependent antithyroid effects.

The present study encompasses the ethnomedicinal consumption of Corchorus depressus (L.) C.Chr. (C. depressus) for diabetes. Samples were subjected to LC-ESI-MS analyses. The n-hexane, methanolic and water extracts were screened for α-glucosidase inhibition and in vivo anti-diabetic studies. Further, antioxidant (DPPH) and anti-inflammatory study was performed via luminol-enhanced chemi-luminescence assay. The identified compounds were docked against the target enzymes of diabetes. The n-hexane fraction (CD-J1) showed IC50 of 8.4 ± 0.1 µg/mL against α-glucosidase enzyme. The sub fractions CD-12 and CD-13 of CD-J1 obtained after flash column chromatography displayed further reduced IC50 values of 4.3 ± 0.1 and 6.3 ± 0.1, respectively, as compared with standard drug acarbose (IC50 values of 37.5 ± 0.2 µg/mL). Simultaneously, dereplication of most active sub-fraction CD-12 by LC-ESI-MS led to the identification of strophanthidin and some other active metabolites responsible for anti-diabetic activity. Molecular docking of strophanthidin with α-glucosidase and α-amylase revealed high affinity for these target enzymes. [ABSTRACT FROM AUTHOR]
