Although post-distillation side-streams of basil (Ocimum basilicum L.) pose significant economic and environmental challenges, they also bring forth new opportunities in the flavor industry. Thus, the objective of the current study was to assess the phenolic profile of basil side-stream extracts to identify key compounds and to evaluate their taste properties, using liquid chromatography–tandem mass spectrometry (LC-MS/MS) analysis, flavor prediction tools and molecular docking. In particular, 52 phytoconstituents, mainly phenolic acids, salvianolic acids, flavonoids and fatty acids derivatives, were elucidated in the side-streams of two different basil varieties (Minimum and Genovese) harvested and distilled in early and late autumn, highlighting the effect of pre-harvest factors on basil’s phenolic fingerprint. Furthermore, the results of tests undertaken using taste prediction tools showed that most of the identified compounds were very likely to taste bitter, while six of them (caffeoylferuloyltartaric acid, isoquercetin, lithospermic acid A, sagerinic acid, salvianolic acids C and F) presented a high bitterant capacity (70–90%). Moreover, according to molecular docking studies, these compounds exhibited a stronger binding affinity to the hTAS2R46 bitter receptor compared to its known agonist, strychnine. This outcome and consequently their bitterness were mainly attributed to interactions with Glu265, Thr180 and/or Trp88 through the formation of direct hydrogen bonds. Therefore, the present results provide insights into the taste profiles of basil side-streams, leading to more sustainable and innovative uses of aromatic herbs residues.

Basil is a highly valued aromatic plant worldwide, and drying is one of the best ways to preserve its leaves. Through a theoretical approach, the microwave drying of basil leaves can be modeled, and the effective diffusivity can be determined. However, using a model that considers moisture diffusion in the presence of intensive microwave energy is crucial. This study proposed a theoretical model to simulate the microwave drying of basil leaves in a thin layer. The model assumed that the material is homogeneous and isotropic, with the effective diffusivity depending on the microwave power. The model was solved numerically and validated with experimental data. The study also examined the effect of the microwave power on the color and bioactive properties during drying. The drying time was reduced by 60%, by increasing the microwave power from 199 W to 622 W. The effective diffusivity was found to be directly proportional to the microwave power. Drying at low powers was found to cause basil pigment degradation. However, drying at a power of 622 W resulted in better preservation of the leaves without browning. Finally, microwave drying negatively affects the bioactive compounds, as the phenolic content and antioxidant capacity in all the powers evaluated were significantly lower than in fresh basil leaves.

Abstract Background The biochemical and growth changes resulting from exposure of basil (Ocimum basilicum L.) seedlings to silver nanoparticles and silver were investigated. Over a two-week period, seedlings were exposed to different concentrations (0, 40, and 80 ppm) of silver nanoparticles and silver. Results Our findings revealed that at concentrations of 40 and 80 ppm, both silver nanoparticles and silver nitrate led to decreased weight, root and shoot length, as well as chlorophyll a and b content. Conversely, these treatments triggered an increase in key biochemical properties, such as total phenols, carotenoids and anthocyanins, with silver nanoparticles showing a more pronounced effect compared to silver nitrate. Moreover, the levels of malondialdehyde (MDA) and hydrogen peroxide (H2O2) rose proportionally with treatment concentration, with the nanoparticle treatment exhibiting a more substantial increase. Silver content showed a significant upswing in both roots and leaves as treatment concentrations increased. Conclusions Application of varying concentrations of silver nanoparticles and silver nitrate on basil plants resulted in reduced growth and lower chlorophyll content, while simultaneously boosting the production of antioxidant compounds. Notably, anthocyanin, carotenoid, and total phenol increased significantly. However, despite this increase in antioxidant activity, the plant remained unable to fully mitigate the oxidative stress induced by silver and silver nanoparticles.

This research delves into phenylpropanoid metabolism, focusing on phenylpropene biosynthesis in the methyleugenol chemotype of basil (Ocimum basilicum L.). We isolated peltate glandular trichomes (PGTs) from basil leaves to eliminate primary metabolic influences, offering a unique perspective into these complex processes. Vermicompost, chosen for its eco-friendly composition and superiority in invigorating phenylpropanoid metabolism. In this study, we investigated the impacts of solid and tea-form vermicompost applications at 0%, 10%, and 25% doses on the methyleugenol chemotype of basil, focusing on the expression levels of PAL, 4CL, EGS, EOMT, and CVOMT genes and phenylpropene accumulation in the peltate glandular trichomes. Results showed that 10% solid vermicompost (SV) application increased 4CL expression level at 236%, while 25% SV application further enhanced EOMT and CVOMT expressions to towering values by 7,494-fold and 19,643-fold, respectively. SV applications did not significantly impact eugenol accumulation but suppressed chavicol biosynthesis. Methyleugenol and methylchavicol accumulation rose in a dose-dependent manner, with significant increases observed in the 25% SV application. A positive correlation was found between CVOMT expression and accumulation rates of methyleugenol and methylchavicol phenylpropenes following SV applications. Conversely, vermicompost tea (VT) applications led to mixed gene expression patterns and reduced eugenol and methyleugenol ratios in peltate glandular trichomes compared to control. In summary, the notably high gene expressions observed in the results of our preliminary study offer a new perspective in the field of phenylpropanoid metabolism. This underscores the value of utilizing single-cell type PGTs for examining secondary metabolic pathways in plants and demonstrates the impact of vermicompost on phenylpropene production.

This study aimed to analyze the formulation of an aromatherapy balm composed of the essential oils O. basilicum L. and C. citratus DC. Experimental research design involving the compilation of five balm formulations at concentrations of 0, 5, 10, 15, and 20%. For four months, balm formulations were made, and physical, chemical, and microbiological tests were carried out, which were further analyzed descriptively. The findings showed that the yield of essential oils obtained from distillation reached 0.19% w/v (O. basilicum L.) and 0.24% w/v (C. citratus DC). All formulations at concentrations of 0, 5, 10, 15, and 20% passed the organoleptic tests for topical dosage balms. This means that they were semisolid, smelled like essential oils, and were yellowish-brown based on the raw materials. The balm is completely homogeneous; there are no granules, and the color is evenly spread throughout the smear. The pH for the topical preparations ranged from 6–7, the dispersion power ranged from 5.02–6.10, and the adhesion ratio ranged from 2–6 depending on the concentration. Microbiological testing revealed that the aromatherapy balm was free of S. aureus and P. aeruginosa bacteria.

Considering the current global climate and demographic conditions, combined with the growing demand for food diversification, the need for innovative functional foods that adhere to the principles of the circular economy is becoming clear. Therefore, this research aims to identify an appropriate cultivation system and growth substrate to maintain a high germination rate and produce basil aromatic microplants with superior quality traits that are entirely edible, together with the substrate. Microplants were grown in both aseptic (AS) and non-aseptic (NAS) systems. Both AS and NAS experiments were conducted in vitro using eco-innovative production technology. Moreover, various growth substrates were tested, such as perlite, agar, banana peel, peat, and their combinations. The analyses focused on the germination capacity, morphometric measurements, and biochemical analyses of the microplants. The results showed that the edible agar-based substrate, used in both AS and NAS, increased the germination capacity up to 95.00 ± 0.30%, while peat provided a germination capacity of only 12.07 ± 1.27% under AS conditions and 6.07 ± 0.35% under NAS conditions. Most biochemical analyses indicated that AS conditions are more suitable for basil microplant production, increasing the dry matter content, total phenolic content, total flavonoid content, and total antioxidant capacity compared to NAS conditions. These findings support the adoption of a new eco-innovative technology that provides organic basil microplants, which are fully usable along with the edible agar substrate.

The effects of melatonin (MT) on the growth and antioxidant responses of basil (Ocimum basilicum L.) exposed to copper and zinc excess stress are investigated. For this purpose, seedlings were exposed to different concentrations of copper oxide (0, 50 and 150 µM), zinc oxide (0, 50 and 100 µM) and melatonin (0 and 100 µM) for 14 days. Growth and biochemical parameters, the activity of some antioxidant enzymes, and phenylalanine ammonia lyase (PAL) and some of the main nutritional elements in the shoot and root of seedlings were measured. The results of this study showed that the excess of copper (Cu 50 and 150 µM) and zinc (Zn 50 and 100 µM) causes a decrease in growth, and a higher oxidative stress indicator such as hydrogen peroxide and malondialdehyde (MDA) content. The homeostasis balance of mineral nutrition of basil seedlings was also disrupted under copper and zinc stress. Melatonin treatment in Cu, Zn stressed seedlings improved growth parameters by reducing the levels of hydrogen peroxide (H2O2) and malondialdehyde (MDA) and increasing the activity of PAL and antioxidant enzymes. Melatonin also regulated the distribution of minerals in basil seedlings under Cu and Zn stress conditions. The results of this research showed that MT can improve the tolerance of basil seedlings against copper and zinc stress by modulate growth and antioxidant responses and regulating mineral nutrition.

Having in mind food security and the fact that basil (Ocimum basilicum L.) is used as fresh seasoning, the development of innovative technologies for its cultivation is required. This study aimed to isolate and characterize plant growth-promoting rhizobacteria (PGPR) isolates from basil rhizospheric soil and monitor the effects of their application on basil growth under different water stress conditions. Isolation, determination of isolates biochemical and PGP properties, evaluation of isolates influences on seed germination and parameters of growth of basil plant, growing under well-watered conditions (70% water holding capacity, WHC), under water deficit stress (35% WHC), and flooded conditions (95% WHC), were done. A total of five representative bacterial isolates were selected: Two Azotobacter isolates (A13, A14), one Pseudomonas isolate (P57), and two Bacillus isolates (B79, B82). The results of this experiment revealed that rhizospheric bacteria of O. basilicum L. var. minimum have multiple biochemical and PGP properties. The most intensive reactions on tested abiotic stressors - drought (higher total phenolics, reduced glutathione, and malondialdehyde content) and flooding (higher superoxide dismutase activity) - were from basil plants inoculated with Pseudomonas sp. P57 isolate, yet along with Azotobacter sp. isolate A13. The highest number of germinated seeds was obtained with the A13 isolate (96.0%), while the highest response for vigour index was observed with Azotobacter isolates (7200.0% and 5628.0%). In well-watered conditions, basil mass inoculated with P57 was 34.2% higher than control. In drought-stressed conditions, plant mass inoculated with A13 isolate was 90% higher than control. In flooded-stressed conditions, the plant mass inoculated with Azotobacter and Pseudomonas isolates increased by more than 100%. [ABSTRACT FROM AUTHOR]

Various environmental factors not only affect plant growth and physiological responses individually but also interact with each other. To examine the impact of light intensity on the drought responses of sweet basil, plants were subjected to maintenance of two substrate volumetric water contents (VWC) using a sensor-based automated irrigation system under two distinct light intensities. The VWC threshold was set to either a dry (0.2 m3·m−3) or sufficiently wet condition (0.6 m3·m−3) under low (170 μmol·m−2·s−1) or high light intensities (500 μmol·m−2·s−1). The growth and physiological responses of sweet basil (Ocimum basilicum L.) were observed over 21 days in the four treatment groups, where the combination of two environmental factors was analyzed. Under high light intensity, sweet basil showed lower Fv/Fm and quantum yield of PSII, compared to that under low light intensity, regardless of drought treatment. Fourteen days after drought treatment under high light intensity, stomatal conductance and the photosynthetic rate significantly reduced. Whereas plants under low light intensity showed similar stomatal conductance and photosynthetic rates regardless of drought treatment. Assessment of shoot and root dry weights revealed that plant growth decline caused by drought was more pronounced under high light intensity than under low light intensity. Thus, sweet basil showed significant declines in growth and physiological responses owing to drought only under high light intensity; no significant changes were observed under low light intensity.

Basil is an aromatic herb that plays an important role within the culinary traditions of many cultures. Despite basil's prevalence within a variety of food and medicinal products, the phenolic composition and antioxidant properties of many Ocimum basilicum L. subspecies have yet to be determined. Therefore, this study analyzed twenty-two commercially available basil cultivars and classified them into unique chemotypes based on commonalities in phenolic acid profiles among varieties. Hierarchical cluster analysis was used to identify chemotypes, and results showed that basil cultivars with the highest total phenolic content and strongest antioxidant properties were characterized as a caffeic acid rich chemotype. Additionally, cultivar had a significant effect on total phenolic content as well as CUPRAC (cupric ion reducing antioxidant capacity) and ORAC (oxygen radical absorbance capacity) antioxidant capacities. Statistical differences in phenolic acid composition also existed among basil varieties and morphotypes. For example, green Genovese-type basils had high phenolic contents and associated antioxidant capacities while lettuce-leaf basil morphotypes had the lowest.

The present study was conducted to evaluate the effectiveness of different doses of gamma rays (25, 50, 100, 125 and 150) Gy on antioxidant enzymes and lipid peroxidase (MDA) of Ocimum basilicum L using C60 as an irradiation source. Radiation processing increased the total antioxidants of basil, this increase appeared at low doses (125 Gy) as shown in a significant increase in SOD, CAT, POD and MDA values. Defects in studied parameters increased with increasing gamma doses. Results indicated that the irradiation process can facilitate the utilization of basil as a preservative ingredient in the food and pharmaceutical industry. [ABSTRACT FROM AUTHOR]

The aim of this study was to discriminate between different disinfection protocols applied to common basil seeds for in vitro establishment on Murashige & Skoog medium. The aim of this approach was not only to overcome seed dormancy, but also to decisively influence the germination process in order to achieve a significant increase in the proportion of seeds that germinate successfully. In the Colombian context, where some 156 species of medicinal plants are currently marketed, basil (Ocimum basilicum L.), originally from Asia Minor, stands out as one of the most widely used plants in the world. In the department of Valle del Cauca, medicinal plants have emerged as protagonists in contrast to the monoculture of sugar cane (Saccharum Officinarum L.) that dominates the region. However, basil faces significant challenges related to seed dormancy, a condition that negatively affects germination and therefore directly affects yield. In this scenario, 21 treatments were carried out in the Biological Sciences Laboratory of the Central Unit of Valle del Cauca, which showed a marked variability and influence in phenological development, especially in stem and leaf growth. Treatment 12 (0.7% NaClO) showed the highest percentage of basil seed germination (80%). It is imperative to explore new protocols that effectively contribute to the basil production process by overcoming seed dormancy.

• Methyl jasmonate (MJ) mitigated salt stress effects on purple basil. • MJ increased chlorophyll, anthocyanin, sugars, and phenolics in purple basil. • MJ increased the growth and post-harvest quality of purple basil. The objective of this study was to evaluate the potential of methyl jasmonate (MJ) in mitigating the negative effects of salt stress on purple basil. For this, plants were grown in an entirely randomized design in a 3 × 2 factorial scheme (salinity × MJ treatments), and seven replicates. Salinity levels corresponded to non-stress (irrigation water without NaCl addition), mild stress (40 mM NaCl), and severe stress (80 mM NaCl), and MJ treatments corresponded to control (0 µM – water) or 1 mM solutions, applied as leaf sprays. The growth, physiology, and post-harvest attributes of purple basil were determined. Salt stress impaired growth, photosynthetic capacity, chlorophyll content, and relative water content, while it increased electrolyte leakage (P ≤ 0.05). However, the application of exogenous methyl jasmonate (MJ) mitigated the effects of salt stress on growth and gas exchange in purple basil. MJ also increased chlorophyll and relative water content while decreasing electrolyte leakage. Mild and severe salt stress differentially impacted chlorophyll fluorescence, while methyl jasmonate (MJ) partially mitigated these effects. Salt stress also reduced the contents of anthocyanins, sugars, and phenolic compounds, whereas MJ increased their levels under both non-stressed and salt-stressed conditions. In conclusion, MJ alleviated the effects of mild and severe salt stress and enhanced the post-harvest quality of purple basil. [ABSTRACT FROM AUTHOR]

The present study was conducted to investigate the effects of Ocimum basilicum L. (OB) extract on learning and memory impairment in aged rats. Male rats were divided into the following experimental groups: Group 1 (control): including 2 months old rats, Group 2 (aged) including 2 years old rats, Groups 3–5 (aged-OB): including 2 years old rats received 50, 100, and 150 mg/kg OB for 8 weeks by oral gavage. Aging increased the delay to find the platform but, however, decreased the time spent in the target quadrant when tested by Morris water maze (MWM). Aging also reduced the latency to enter the dark chamber in the passive avoidance (PA) test compared to the control group. Moreover, interleukin-6 (IL-6) and malondialdehyde (MDA) levels were raised in the hippocampus and cortex of aged rats. In contrast, thiol levels and enzymatic activity of superoxide dismutase (SOD) and catalase (CAT) significantly reduced. In addition, aging significantly reduced BDNF expression. Finally, OB administration reversed the mentioned effects. The current research showed that OB administration improves learning/memory impairment induced by aging. It also found that this plant extract protects the brain tissues from oxidative damage and neuroinflammation. [ABSTRACT FROM AUTHOR]

An unprecedented and direct PS‐MS (paper spray ionization mass spectrometry) method was proposed for the detection of native peptides, that is, glutathiones (GSHs), homoglutathiones (hGSHs), and phytochelatins (PCs), in basil (Ocimum basilicum L.) roots before and after cadmium exposure. The roots were submitted to cold maceration followed by sonication with formic acid as the extractor solvent for sample preparation. PS‐MS was used to analyze such extracts in the positive mode, and the results allowed for the detection of several GSHs, hGSHs, and PCs. Some of these PCs were not distinguished in the control samples, that is, basil roots not exposed to cadmium. Other PCs were noticed in both types of roots, uncontaminated and cadmium‐contaminated, but the intensities were higher in the former samples. Moreover, long‐time exposure to cadmium stimulated the formation of some of these PCs and their cadmium complexes. The results, therefore, provided some crucial insights into the defense mechanism of plants against an external stress condition due to exposure to a toxic heavy metal. The present study represents a promising alternative to investigate other crucial physiological processes in plants submitted to assorted stress conditions. [ABSTRACT FROM AUTHOR]

BASIL , *SAGE , *SAVORY (Herb) , *LAVENDERS , *YERSINIA enterocolitica - Abstract
The aim of the study was to evaluate the antimicrobial activity of the extracted plants basil (Ocimum basilicum L.), sage (Salvia officinalis L.), lavender (Lavandula officinalis L.), immortelle (Helichrysum italicum (Roth) G. Don), savory (Satureja montana L.), and rosemary (Salvia rosmarinus Spenn.) against foodborne and clinical pathogens. Dried plants were used in the production of Dalmatian cow's milk hard cheese at concentrations of 0.5, 1.0, 1.5, and 2% to evaluate the microbiological safety and sensory properties of novel cheeses. The broadest antimicrobial activity was found in rosemary and sage, inhibiting ten indicator pathogens, and the strongest antimicrobial activity was found in immortelle and sage, which showed the widest zones of inhibition. The most sensitive indicators were Staphylococcus species and Yersinia enterocolitica. The supplemented cheeses met the official microbiological criteria and were mycotoxin negative. The surface mycobiota of control and experimental cheeses consisted mainly of Penicillium sollitum, based on the sequence analysis of the beta-tubulin and calmodulin genes. The antifungal effect of the added plants was clearly demonstrated in cheeses with added basil and sage (p < 0.05). [ABSTRACT FROM AUTHOR]

To investigate the effect of horsetail extract containing high silicon on morphological traits, growth, content, and compositions of essential oil of sweet basil (Ocimum basilicum L.) an experiment turned into carried out in the shape of a randomized complete block design with three replications. Foliar treatment of horsetail extract with zero, 0.5, 1, and 2% concentrations was applied on 6–8 leaf plants. The assessed traits include plant height, number of leaves per plant, number of sub-branches, leaf area index, plant fresh weight, plant dry weight, total anthocyanin, the content of total phenol and total flavonoid, antioxidant activity, essential oil content, and compounds were measured. The findings demonstrated that the increase of silicon-containing horsetail extract enhanced the improved increase in growth and phytochemical trait values. The use of horsetail extract in the 2% treatment increased plant height, the number of leaves per plant, the number of sub-branches, leaf area index, fresh weight, and dry weight of the plant by 49.79, 45.61, 91.09, 99.78, 52.78 and 109.25%, respectively, compared to the control. The highest content of total phenol (2.12 mg GAE/g DW), total flavonoid (1.73 mg RE/g DW), total anthocyanin (0.83 mg C3G/g DW), and antioxidant activity (184.3 µg/ml) was observed in the 2% extract treatment. The content of essential oil increased with increasing the concentration of horsetail extract, so the highest amount of essential oil was obtained at the concentration of 2%, which increased by 134.78% compared to the control. By using GC–MS, the essential oil was analyzed. The main components of the essential oil include methyl eugenol (12.93–25.93%), eugenol (17.63–27.51%), 1,8-cineole (15.63–20.84%), linalool (8.31–19.63%) and (Z)-caryophyllene (6.02–14.93%). Increasing the concentration of horsetail extract increased the compounds of eugenol, 1,8-cineole, and linalool in essential oil compared to the control, but decreased the compounds of methyl eugenol and (Z)-caryophyllene. Foliar spraying of horsetail extract, which contains high amounts of silicon, as a stimulant and biological fertilizer, can be a beneficial ingredient in increasing the yield and production of medicinal plants, especially in organic essential oil production.

Basil (Ocimum basilicum L.) is an aromatic plant used in foods, pharmaceuticals, and in cosmetics. In this study, the morphology and yield of 17 different basil genotypes and three cultivars (Moonlight, Midnight, and Dino) from Türkiye were analyzed in 2019 and 2020. A wide range of variations in plant height, number of branches, and weights of fresh and dry herbs weights were observed. The genotypes PI 531,396 from Hungary, PI 174,284 from Türkiye, PI 253,157 from Iran, and the Dino cultivar had the highest plant yield compared with the other genotypes and cultivars. The leaf color parameters (L*, a*, b* C*, H° and WI) were also determined for the plants. The highest lightness (L*) values were recorded in the PI 190,100 genotype, and the highest yellowness/blueness (b*) and hue angle (H°) values were recorded in the PI 207,498 genotype. The highest redness/greenness (a*), chroma (C*), and whiteness index (WI) values were recorded in the PI 197,442, PI 190,100, and PI 531,396 genotypes, respectively. Except for the L* values, the leaf color parameters clustered on the same side of the principal component analysis (PCA) axis. Dendrogram analysis divided the genotypes and cultivars into two main groups, and the main A group contained the cultivar Dino only. Therefore, the study identified important genotypic characteristics of the examined basil genotypes and cultivars that could be utilized to develop new cultivars. [ABSTRACT FROM AUTHOR]

The present study was carried- out during the two successive seasons of 2017 and 2018 at Banger AL-Sokar region, Borg AL-Arab, Alexandria, Egypt to study the effect of water stress, salicylic acid and irrigation rate on vegetative growth and oil yield of Ocimum basilicum L. plant in newly reclaimed land. Three levels of water stress were determined as a percentage of field water capacity 100, 75 and 50% and four concentrations of salicylic acid (SA) as foliar spray 0, 0.1, 0.2, and 0.4 mM were used, as well as two irrigation interval rates (every 4th and 7th days were applied. The results showed that spraying SA with low concentration i.e., 0.1- 0.4 mM led to improve the vegetative growth and oil yield of sweet basil plants under water stress. The highest oil yield (7.38%) was achieved at 75% of field capacity in second cut in the second seasons with spraying of SA at 0.2 mM irrigated every 4 days as a moderate stress.

This study investigated the effects of biochar treatments on the growth, nutrient content and some biochemical properties of basil. Biochars obtained from two different biomasses, rice husk (RBC) and tomato harvest waste (TBC), were applied at a dose of 2% to the growing medium consisting of a 1 : 1 soil and peat mixture. No biochar-added medium (1 : 1 soil and peat) was used as a control. The experiment was established in a completely randomized design with six replications for each treatment. At the end of the study, the height, number of lateral branches, total herb weight, and leaf weight of the plants were measured. In addition, chlorophyll contents in SPAD (Soil Plant Analysis Development), different nutrients and total phenolics contents, and antioxidant activities were analyzed. As a result of the study, the effects of biochar treatments differed depending on the biomass source. RBC significantly increased plant height, total herb weight, and leaf weight while negatively affecting the number of lateral branches. TCB did not cause any significant variation in plant height and number of lateral branches. While RBC provided a slight increase in leaf weight compared to the control, it did not cause a significant change in plant height, total herb weight, and the number of lateral branches. Except for a slight increase in K content due to RBC application, both biochar treatments did not cause a significant increase in leaf nutrient content. While RBC treatment did not cause a significant change in total phenol, it caused an increase in antioxidant activity. TBC application decreased the SPAD value from 22.4 in the control to 20.4.

The progressive study aimed to determine the effects of biofertilizers (Azotobacter and Pseudomonas) on active chemical compounds of sweet basil (Ocimum basilicum L.), carried out in 2023 at the Afghan City, Kerbala, Iraq. The experiment set out in a randomized complete block design (RCBD) with a factorial arrangement and three replications. The study comprised two factors: the first was Azotobacter (control, 50, 100, 150 g/bacteria), and the second factor was Pseudomonas (control, 50, 100, 150 g/bacteria). Both biofertilizers attained mixing with seeds before planting. Results revealed significant differences among the various concentrations of Azotobacter and Pseudomonas and their interactions. Azotobacter and Pseudomonas treatment with same dilution (150 g bacteria-1) provided the highest mean values for active chemical compounds in the essential oil, i.e., camphor (3.70 and 4.56 mg g-1), linalool (24.83 and 24.90 mg g-1), pinene (1.09 and 1.38 mg g-1), myrcene (13.64 and 12.84 mg g-1), and limonene (18.16 and 17.76 mg g-1), respectively.

Relevance. Basil is one of the most popular aromatic plants grown in the world. Various species and forms of Ocimum spp. differ in the nature of growth, color and aromatic composition. The VIR basil collection is represented by 452 accessions of six species from 55 countries. The expansion of the assortment of basil, as well as the identification of competitive adaptive cultivars with high economically valuable traits, determines the need to study and identify promising species and forms of Ocimum spp. The purpose of our work was to study accessions of basil (Ocimum basilicum) from the VIR collection by morphological and phenological traits and to identify accessions that have a complex of economically valuable traits for further use in the breeding.Materials and methods. The studies were carried out at the Federal Research Center N. I. Vavilov All-Russian Institute of Plant Genetic Resources (VIR) at the VIR Pushkin and Pavlovsk Laboratories in 2019-2021 in open ground conditions. The material of the study was 66 accessions of the VIR basil collection of various agrobiological status and ecological and geographical origin. When analyzing the material, phenological observations, biometric measurements and morphological description of plants were carried out. These measurements were carried out in the phase of mass flowering.Results. As a result of the study, the degree of variability of the main phenological and morphological features was revealed. Accessions of basil were selected according to such traits as early maturity, plant height, weight of one plant and cold resistance, which can be used as starting material for breeding. The studied accessions are grouped into 7 varieties of two subspecies (subsp. basilicum and subsp. minimum): var. basilicum, var. glabratum, var. purpurescens, var. majus, var. diforme, var. minimum and var. chamaeleonicum, and their characteristics are given.

Exposure to N2O5 generated by plasma technology activates immunity in Arabidopsis through tryptophan metabolites. However, little is known about the effects of N2O5 exposure on other plant species. Sweet basil synthesizes many valuable secondary metabolites in its leaves. Therefore, metabolomic analyses were performed at three different exposure levels [9.7 (Ex1), 19.4 (Ex2) and 29.1 (Ex3) μmol] to assess the effects of N2O5 on basil leaves. As a result, cinnamaldehyde and phenolic acids increased with increasing doses. Certain flavonoids, columbianetin, and caryophyllene oxide increased with lower Ex1 exposure, cineole and methyl eugenol increased with moderate Ex2 exposure and l-glutathione GSH also increased with higher Ex3 exposure. Furthermore, gene expression analysis by quantitative RT-PCR showed that certain genes involved in the syntheses of secondary metabolites and jasmonic acid were significantly up-regulated early after N2O5 exposure. These results suggest that N2O5 exposure increases several valuable secondary metabolites in sweet basil leaves via plant defense responses in a controllable system. [ABSTRACT FROM AUTHOR]

ESSENTIAL oils , *SAGE , *BASIL , *SALMONELLA enterica , *FLAME ionization detectors , *DROSOPHILA suzukii - Abstract
The essential oils from Thymus vulgaris, Salvia officinalis, and Ocimum basilicum were extracted by hydrodistillation, characterized by gas chromatography/mass spectrometry, and quantified by gas chromatography/flame ionization detector. The principal constituents were thymol, ρ‐cymene and carvacrol (T. vulgaris); camphor, β‐pinene, and 1,8‐cineole (S. officinalis); and (E)‐anethole, linalool, and 1,8‐cineole (O. basilicum). The essential oil from T. vulgaris was the most effective, forming inhibition halos of 46.16 ± 0.16 and 26.38 ± 0.33 mm, respectively, for Salmonella choleraesuis and Listeria monocytogenes. This essential oil was also more effective against S. choleraesuis, with a minimum inhibitory concentration of 8.85 mg mL−1, and a minimum inhibitory concentration of 17.71 mg mL−1 for L. monocytogenes. No bactericidal activity against S. choleraesuis and L. monocytogenes was observed for the essential oils from S. officinalis, and O. basilicum. Scanning electron micrographs showed that the addition of essential oils left the bacterial cells damaged and deformed. Significant 2,2‐diphenyl‐1‐picrylhydrazyl free radical scavenging capacity and lipid substrate protection were observed in the β‐carotene bleaching assay for the essential oil from T. vulgaris, with IC50 of 231.13 ± 0.53 and 15.25 ± 0.38 μg mL−1, respectively. A dose‐dependent relationship between antioxidant activity and concentrations was observed in the tests. Toxicities of LC50 = 1.24, 3.51 and 1.19 mg mL−1 against Drosophila suzukii flies, respectively, were observed for the essential oils from T. vulgaris, S. officinalis, and O. basilicum. Results suggest that essential oils can be promising antioxidant agents, insecticides, and inhibitors of pathogenic bacteria. [ABSTRACT FROM AUTHOR]

Chilling sensitivity is one of the greatest challenges affecting the marketability and profitability of sweet basil (Ocimum basilicum L.) in the US and worldwide. Currently, there are no sweet basils commercially available with significant chilling tolerance and traditional aroma profiles. This study was conducted to identify quantitative trait loci (QTLs) responsible for chilling tolerance and aroma compounds in a biparental mapping population, including the Rutgers advanced breeding line that served as a chilling tolerant parent, 'CB15', the chilling sensitive parent, 'Rutgers Obsession DMR' and 200 F2 individuals. Chilling tolerance was assessed by percent necrosis using machine learning and aroma profiling was evaluated using gas chromatography (GC) mass spectrometry (MS). Single nucleotide polymorphism (SNP) markers were generated from genomic sequences derived from double digestion restriction-site associated DNA sequencing (ddRADseq) and converted to genotype data using a reference genome alignment. A genetic linkage map was constructed and five statistically significant QTLs were identified in response to chilling temperatures with possible interactions between QTLs. The QTL on LG24 (qCH24) demonstrated the largest effect for chilling response and was significant in all three replicates. No QTLs were identified for linalool, as the population did not segregate sufficiently to detect this trait. Two significant QTLs were identified for estragole (also known as methyl chavicol) with only qEST1 on LG1 being significant in the multiple-QTL model (MQM). QEUC26 was identified as a significant QTL for eucalyptol (also known as 1,8-cineole) on LG26. These QTLs may represent key mechanisms for chilling tolerance and aroma in basil, providing critical knowledge for future investigation of these phenotypic traits and molecular breeding.

This work is aimed at relationships which govern zinc and copper uptake by four popular medicinal herbs: basil (Ocimum basilicum L.), borage (Borago officinalis L.), common nettle (Urtica dioica L.) and peppermint (Mentha piperita L.). They are often grown in soils with significant copper or zinc levels. Herbs were cultivated by a pot method in controlled conditions. Manganese, iron, copper and zinc concentrations were determined by High-Resolution Continuum Source Flame Atomic Absorption Spectrometry. The efficiency of photosynthesis was estimated by measuring the chlorophyll content, water use efficiency, net photosynthesis, intercellular CO2, stomatal conductance, and transpiration rate. Phenolic compounds were determined by the Folin–Ciocalteu method. Analysis of variance showed that herbs grown in soil treated with copper exhibited a lower iron content in roots, while manganese behaved in the opposite way. The only exception was borage, where a decrease in the manganese content in roots was observed. Both copper and zinc supplementations increased the total content of phenolics, while the highest increases were observed for common nettle and basil. Peppermint and borage responded less to supplementation. In the majority of samples, zinc and copper did not significantly affect the photosynthesis. Herbal extracts from common nettle and basil had unique antioxidant properties and may be good free radical scavengers. [ABSTRACT FROM AUTHOR]

The continuous development of drinking water networks is leading to the production of increasing amounts of waste water and sewage sludge. Secondary-treated sewage sludge is called biosolids and can be used as fertilizers in agriculture due to its rich nutrient content. The aim of this study was to evaluate the effects of biosolids mixed with an eroded soil on the morphology, physiology and synthesis of bioactive compounds in basil. The study was performed in pots under laboratory-controlled conditions. In total, four substrates were tested: S1 biosolids 100%, S2 biosolids 15% + eroded soil 85%, S3 eroded soil 100% and S4 control (commercial growing substrate). At the morphological level, a significant increase in plant height, number of branches, fresh biomass and dry biomass was found in the S2 variant. At the physiological level, photosynthesis and chlorophyll content did not vary significantly, but the quantum yield of PSII (ΦPSII) was significantly higher at S1 and S2. The oxidative status evaluated by determining the activity of SOD, POD and CAT enzymes was better in S2 and S3 compared to S3. Regarding the synthesis of bioactive compounds (rosmarinic acid, caffeic acid and gallic acid), it was stimulated in S1 and S2. In conclusion, biosolids application stimulated the stress response mechanisms in basil plants by increasing the quantum yield chlorophyll fluorescence and catalase activity, alleviating the negative effects of eroded soil.

This study presents the modeling of thin layer drying of micropropagated Ocimum basilicum L., some quality characteristics of the dried product, and energy consumption analysis for the dryer used. The experimental drying data obtained from a previous article were used in the statistical analyses. Modeling studies were statistically carried out using the experimental data at a 1 m/s airflow rate and a temperature of 30 °C-50 °C. The statistical analysis showed that the Verma equation was the best-fit model with the lowest chi-square (χ²) and AIC values at all temperatures studied. From statistical analyses using derived drying models, it was found that the D9 equation having a χ² value of 0.0146 and an AIC value of -528.0, was the best model fitting to experimental data. The total phenolic content, flavonoid, and antioxidant capacity of dried basil samples were measured as (2.538 ± 0.029) mg GAE/g, (2.017 ± 0.088) mg quercetin/g, and (2.263 ± 0.001) mmol TEAC/100 g d.w., respectively. From FTIR spectra, dried basil samples had typical functional groups. SEM images showed that a collapse in the surface of the leaves occurred. But, this collapse is not affecting the functional groups on the surface of the leaves. From energy consumption analyses, the optimum drying temperature was found to be 40 °C. The SMER, MER, and SEC values calculated from energy consumption analysis at 40 °C were 0.0043 kg/kWh, 0.0007 kg/h, and 234.81 kWh/kg, respectively. [ABSTRACT FROM AUTHOR]

Background and Aims: This research focuses on assessing the antioxidant, antifungal and antibacterial properties of Mentha piperita Lamiaceae and Ocimum basilicum Lamiaceae essential oils and their potential synergistic effects with various antibiotics. Methods: The study identifies the chemical composition of M. piperita and O. basilicum essential oils by employing gas chromatography-mass spectrometry (GC-MS), cupric reducing antioxidant capacity (CUPRAC), and 2,2-Diphenyl-1-picrylhydrazyl (DPPH) methods to identify antioxidant activity. The study also uses the minimal inhibitory concentration (MIC) method for the antibacterial and antifungal activity tests. Results: The main constituents of M. piperita are menthol (51.89%), L-menthone (17.81%), L-menthol (10.17%), and menthyl acetate 6.29%. The main constituents of O. basilicum are 65.51% estragole, 18.51% L-linalool, 2.69% bisabolene, and 2.66% trans-4-methoxycinnamaldehyde. With regard to the DPPH method, IC50 values of 0.028 and 0.019 were found for M. piperita and O. basilicum, respectively, based on the inhibition values. The results for the CUPRAC method indicate O. basilicum to show more antioxidant activity than M. piperita. According to the MICs, the essential oils are effective against bacteria at 1:4-1:16 dilutions, while the MIC values for the oil mixture (1:1) are significantly lower at a dilution of up to 1:2048. When combining the oils combined with the antibiotics (i.e., tobramycin and ceftazidime), they provide a synergistic activity against Staphylococcus epidermidis, Escherichia coli, and Klebsiella pneumoniae. The antifungal activity tests reveal no sufficient activity against the mold Aspergillus niger, while a limited effect was observed against the yeast Candida albicans. Conclusion: The results show that the studied essential oils, especially their mixture at a 1:1 ratio, could be a good treatment option either alone or as a drug adjuvant due to their antibacterial and antioxidant properties.

Plant-derived bioactive molecules are increasingly utilized in food processing as natural additives, driven by a growing interest in healthier lifestyles. This trend has spurred industries to reformulate products to meet the demands of health-conscious consumers. This study investigates the phenolic extract and essential oil of O. basilicum L. obtained via ultrasound-assisted extraction and microwave-assisted extraction, respectively. Characterization using ultra-high-performance liquid chromatography coupled with high-resolution mass spectrometry (UHPLC-HRMS) for the basil phenolic extract (BPE) and Gas Chromatography-Mass Spectrometry (GC-MS) for the basil essential oil (BEO) identified 82 compounds in BPE and 51 compounds, with rosmarinic acid and estragole as the main constituents, respectively. Both BPE and BEO exhibited significant antioxidant capacity. BPE showed higher antioxidant activity, with IC 50 values of 0.740 ± 0.023 mg/mL against DPPH•, 0.408 ± 0.02 mg/mL for ABTS+•, and 0.289 ± 0.02 mg/mL for iron chelation. Conversely, BEO demonstrated IC 50 values of 16.296 ± 0.394 mg/mL, 0.6870 ± 0.0203 mg/mL, and 3.9 ± 0.12 mg/mL for DPPH•, ABTS+• scavenging assays, and iron chelation, respectively. The growth inhibitory effect of BEO surpassed that of BPE against microbial strains, achieving total growth inhibition against C. albicans with a minimal inhibitory concentration (MIC) value of 0.04 mg/mL. BPE exhibited inhibitory effects against MRSA with a zone of inhibition of 19 ± 1.15 mm, while the lowest MIC value was observed against E. coli at 0.38 ± 0.03 mg/mL. These findings underling basil's potential health-boosting, emphasizing its abundance in phenolic and volatile compounds. [Display omitted] • Ocimum basilicum.

The application of organic amendments, biochar, and wood distillate (WD), as well as the exposure to UV-B radiation, are two sustainable ways to enhance soil fertility and increase plant nutraceutical quality, respectively. However, they have always been studied separately, without testing the eventual synergistic or antagonistic effect when applied together. The present study investigated the effects of biochar (2% w/w), WD (1:100), and their combination (BWD) on some biometric and biochemical parameters of basil plants (Ocimum basilicum L.) exposed to different doses of UV-B radiation (0, 1, 2 h d−1; UV-B irradiance of 1.36 W m−2) in controlled conditions. Root and stem length and weight were not affected by soil amendments, while 1 h d−1 UV-B increased the length (+28%) and weight (+62%) of the aerial part. When combining the above- and below-ground factors, a decrease in root length was observed in the 2 h d−1 UV-B-treated plants in both WD (−36%) and BWD (−39%) treatments. The co-application of below- and above-ground treatments generally decreased phenolic and flavonoid concentration in both fully expanded leaves and vegetative shoot apices. This preliminary study highlights an antagonistic action of the combination of the investigated factors, at these doses, on the plant growth and metabolism that should be considered.

The priming method is a technique that can greatly improve seed performance and provide high-quality seeds for successful production. In this study, the effect of hormopriming (GA3 and IAA), halopriming (MgSO4 and KNO3), osmopriming (AA, H2O2) and hydropriming (H2O) on the germination, as well as initial stages of growth and development of basil (Ocimum basilicum L. cv. 'Genovese') were investigated. The application of different priming methods not only improved the germination performances of basil, but also significantly influenced the growth of seedlings (root length, shoot length, fresh mass, and vigor index) with the best results achieved by priming with GA3 and H2O2. In addition, it has been found that the concentration of photosynthetic pigments and soluble protein content can be improved by the appropriate priming treatment. The most favorable effect on the examined parameters was achieved during treatment with H2O2.

Dynamic crop models are powerful tools for evaluating crop responses to alternative management options. These models consist of various input parameters that need calibration before being implemented in a new environment. Sensitivity analysis (SA) has proven to be an efficient method for identifying dominant model parameters. This study aimed to determine influential parameters of the AquaCrop model for basil and also quantify output uncertainty under different nitrogen fertilizer rates. The Sobol' SA method was employed to compute both first-order and total-order sensitivity indices. Results indicated that normalized water productivity (WP*) and crop coefficient (KcTr,x) were the most influential parameters across all treatments. Furthermore, as fertility stress increased, the interaction effects among parameters decreased. The temporal analysis of model output (biomass) revealed that parameter sensitivities were highly time-dependent. In addition, the uncertainty of predicted biomass was determined using combined violin and box plots. Results demonstrated that the optimal nitrogen fertilizer application rate extended the distribution of model output. In summary, these findings offer valuable insights for model simplification and effective decision-making. [ABSTRACT FROM AUTHOR]

The salinity and drought are abiotic stresses that affect the agriculture which foster growth retardation, physiological abnormalities, and lower production output of field crops throughout the world. Plant responses under salinity conditions is a scientific problem to be explored. The objective of this study was to determine the effect of vermicompost humates as a NaClstress mitigator on photosynthesis, transpiration, water potential and biochemical variables as protein, proline, and total foliar carbohydrates of two basil varieties to elucidate the differential response of both varieties to the NaCl. The experiment was carried out through a completely randomized design with a trifactorial arrangement of 2×3×2, where factor A consisted of two varieties, Napoletano and Sweet Genovese, factor B included three NaCl concentrations (0, 50, and 100 mM), and factor C were one concentration of vermicompost humates (1/60) and distilled water as control, with six replications per treatment. The results showed a differential response among varieties in all variables measured. The vermicompost humates had a bio stimulant and mitigating stress effect on the physiological and biochemical variables. Napoletano is the most tolerant NaClstress variety, exhibiting the highest values in all physiological and biochemical variables. [ABSTRACT FROM AUTHOR]

The objective of this study is to determine the effect of endogenous plant matrix components, dose and digestion-related factors on the bioaccessibility of rosmarinic acid and basil co-compounds in in vitro digestion conditions. Different forms of administration, i.e., basil raw plant material, dry extract, and isolated rosmarinic acid at various doses, were applied for the digestion experiment. To evaluate the contribution of biochemical and physicochemical digestion factors, samples were subjected to a full digestion process or treated only with a digestion fluid electrolyte composition without using biochemical components (i.e., digestion enzymes and bile salts), and bioaccessibility was monitored at the gastric and intestinal steps of digestion. The results showed that the components of the endogenous raw plant matrix significantly limited the bioaccessibility of rosmarinic acid and basil co-compounds, especially at the gastric stage of digestion. Physicochemical digestion factors were mainly responsible for the bioaccessibility of basil phytochemicals. Higher doses allowed maintenance of bioaccessibility at a relatively similar level, whereas the most negative changes in bioaccessibility were induced by the lowest doses. In conclusion, the determination of the bioaccessibility of bioactive phytochemicals from basil and factors influencing bioaccessibility may help in better prediction of the pro-health potential of this plant.

The study evaluated the impacts of Mycorrhiza (Bio1), Azotobacter (Bio2), and Trichoderma (Bio3) on the grown, fresh-dry herb yield, biological activity, essential oil productivity, and quality of basil. A reduced application of chemical fertilizer plus Trichoderma, Azotobacter, Mycorrhiza, inoculant alone bio-fertilizers, combined with the bio-organic fertilizers, with using the 100% rate of the conventional chemical fertilizer and control. The results showed that the application with the inoculant alone or combined with the bio-organic fertilizers increased the herb yield and biological activities. The maximum content of methyl chavicol, geranial and citral was obtained fertilized with Bio1 + Bio2 + Bio3, 50% IO + Bio3, 50% IO + Bio2. Especially, application of Bio1 + Bio2 fertilizer has great potential for improving antioxidant activity, total phenolic and flavonoid contents. Thus, the results suggest that the application of bio-fertilizers could be employed in combination with the appropriate rates of chemical fertilizers to get maximum benefits regarding herb yield, biological activity and essential oil component.

BACKGROUND: Despite the optimal characteristics of peat, more environmental‐friendly materials are needed in the nursery sector, although these must guarantee specific quantitative and qualitative commercial standards. In the present study, we evaluated the influence of biochar and compost as peat surrogates on yield and essential oil profile of two different varieties of basil (Ocimum basilicum var. Italiano and Ocimum basilicum var. minimum). In two 50‐day pot experiments, we checked the performances of biochar from pruning of urban trees and composted kitchen scraps, both mixed in different proportions with commercial peat (first experiment), and under different nitrogen (N) fertilization regimes (second experiment), in terms of plant growth and volatile compounds profile of basil. RESULTS: Total or high substitution of peat with biochar (100% and 50% v.v.) or compost (100%) resulted in seedling death a few days from transplantation, probably because the pH and electrical conductivity of the growing media were too high. Substrates with lower substitution rates (10–20%) were underperforming in terms of plant growth and color compared to pure commercial peat during the first experiment, whereas better performances were obtained by the nitrogen‐fertilized mixed substrates in the second experiment, at least for one variety. We identified a total of 12 and 16 aroma compounds of basil (mainly terpenes) in the two experiments. Partial replacement of peat did not affect basil volatile organic compounds content and composition, whereas N fertilization overall decreased the concentration of these compounds. CONCLUSION: Our results support a moderate use of charred or composted materials as peat surrogates. © 2023 The Authors.

Aims: Due to the lack of experimental databases, together with the chemical complexity and the dynamic nature of plants' metabolome, most of the metabolites in complex biological materials (like plant in vitro tissue cultures) are not‐annotated, unidentified metabolites. In this study, a method for further metabolite characterization and classification based on the UPLC‐HESI‐HRMS/MS approach for small‐leaved basil (Ocimum basilicum L. var. minimum Alef.) callus and cell suspension culture is presented. Key results: A total of 2168 metabolic features were detected, out of which the database for exact mass metabolic profiling for 1949 metabolites is presented here since there is no available database dedicated to O. basilicum. We further focused on secondary metabolites (particularly phenolic compounds). The presence of 60 different phenolic compounds belonging mainly to the groups of flavonoids, glycosides, terpenoids, and phenolic acids is confirmed. By comparing relative abundances of phenolic compounds from callus culture and cell suspension culture, both grown on two types of media, via svd‐PCА, univariate analysis, post‐hoc tests, and heatmapping of metabolites, we provided a practical example of how resources presented here can be further applied in tissue culture‐based basil metabolomics studies. Utility: This study represents the first approach toward routine targeted investigation of secondary metabolites in basil in vitro cultures and provides various opportunities for new‐generation analyses.

The choice of basil (Ocimum basilicum L.) genotypes determines key attributes such as yield, flavor, and adaptability, contributing significantly to the overall success and sustainability of basil cultivation practices. As the primary aim of this study, seven basil accessions were characterized for both their growth performance and biochemical profile of volatile compounds, enabling the differentiation among distinct chemotypes. As secondary objectives, growth performance and production were evaluated under natural solar radiation conditions (SR100) and with a 30% reduction in solar radiation using a net (SR70). Light use efficiency (LUE) determination revealed the plants' biomass production capability under different solar radiation (SR) conditions. Genotypes A, B, C, and G were characterized by a high levels of linalool, which is typically associated with the "pesto" sauce smell. Lemon basil D exhibited a different chemotype due to the presence of neral and geranial. E and F displayed a different chemotype due to the higher concentration of α-bergamotene. The total fresh harvested biomass was significantly higher in SR70 than SR100 conditions. The second harvest in both SR conditions was the most productive one, while genotype E under SR70 displayed the highest yield. The landraces D and E showed the highest LUE values, indicating their capability in converting the solar radiation into fresh biomass. Plants grown in SR70 conditions registered significantly higher values of plant height, number of branches, and leaf weight. This work aimed to provide valuable insights into the selection of basil genotypes suitable for sustainable agriculture. Conversely, it lays the basis for cultivation aspects pertaining to the crop's adaptability in peri-urban, marginal lands, which are characterized by limited solar radiation. [ABSTRACT FROM AUTHOR]
