Phytochemical Analysis, Isolation, and Characterization of Gentiopicroside from Gentiana kurroo and Cytotoxicity of Biosynthesized Silver Nanoparticles Against HeLa Cells.

Gentiana kurroo Royle, a critically endangered Himalayan herb, is valued in treating leucoderma, syphilis, bronchial asthma, hepatitis, etc. The current investigation performed quantitative and qualitative phytochemical analysis of G. kurroo root extracts prepared in chloroform, methanol, and ethyl acetate. The phenolic and flavonoid contents were the highest in methanol and chloroform extract, respectively. Several pharmacologically important compounds were identified through gas chromatography-mass spectrometry. Antioxidant analysis revealed methanolic extract to be the most efficient scavenger of 2,2-diphenyl-1-picrylhydrazyl (IC50 = 114µgmL-1), hydrogen peroxide (IC50 = 109.9µgmL-1), and superoxide (IC50 = 74.63µgmL-1) radicals. Gentiopicroside was isolated from the methanolic root extract through silica-gel column-chromatography, and the characterization of concentrated fractions was achieved employing various analytical techniques. Pertaining to silver nanoparticle (GkAgNPs) synthesis, different physicochemical parameters were optimized and it was observed that root extract treated with silver-nitrate (0.5mM) at 60°C and incubated in dark for at least 120min after initial color change, yielded GkAgNPs optimally. GkAgNPs were anisotropic and polydisperse and exhibited characteristic surface plasmon resonance (424nm), crystalline face-centered cubic geometry, size (50-300nm), and zeta-potential (- 16.3mV). FT-IR spectra indicated the involvement of phenols and flavonoids in AgNPs synthesis. GkAgNPs were evidenced as strongly cytotoxic (IC50 = 1.964µgmL-1) against HeLa cells and also showed deformed cellular morphology, a significant reduction in viable cell counts and colony-forming efficiency (4.08%). The findings suggest potential applications in drug development for treating serious human diseases. To the best of our knowledge, this study represents the first report on the isolation of gentiopicroside, the bio-fabrication of GkAgNPs using G.kurroo root extract, and their strong bioefficacy against HeLa cells.

Antimicrobial Activity of Biohardened Plant Extracts of Albizia Amara

Albizia amara is an important medicinal plant commonly found in dry forests of India. It belongs to leguminaceae and its common name in telugu is Nallaregoo (or) Chigaraku. All of the plant parts i.e., roots, shoots, leaves, flowers, seeds and bark, were exclusively used in traditional medicine for curing different diseases like diarrhea, skin diseases gonorrhea, poisonous bites and leprosy. Due to its wide pharmacological activities and presence of several therapeutic constituents, Albizia amara has been selected for tissue culture studies in the present investigation. A systemic approach for increasing the survival rate of tissue culture raised A.amara plantlets using bioinoculants was explored . The studies reported that biohardening of tissue cultured plantlets with mixed inoculum of Pseudomonas fluorescens and Trichoderma viride enhanced plant survival rate (82 %). This microbial association helped in inducing systemic resistance in plants to overcome abiotic and biotic stress caused during acclimatization. The phytochemical studies of biohardened plants exhibited high antimicrobial activity due to the presence of more secondary metabolites. These secondary metabolites probably due to their antagonistic properties gave protection against pathogenic attack during transplantation. Phytochemical analysis of different plant extracts like, ethyl acetate, chloroform, methanolic, and petroleum ether extracts were studied. The ethyl acetate extract of dual inoculant treated plants showed maximum antimicrobial activity. In bacteria, it showed maximum zone of inhibition on B.cereus (11.5±1.73), followed by E.coli (10±0.82 mm) . In fungi, it showed maximum inhibition on F.oxysporum (13.25±0.28mm) followed by C.albicans (8.5±0.17mm). The above strategy helped in overall improvement of morphological, physiological and phytochemical characteristics of tissue culture plantlets.

Improved Skin Barrier Function Along with Hydration Benefits of Viola yedoensis Extract, Aesculin, and Schaftoside and LC-HRMS/MS Dereplication of Its Bio-Active Components

The skin hydration level is a key factor that influences the physical and mechanical properties of the skin. The stratum corneum (SC), the outermost layer of the epidermis, is responsible for the skin’s barrier function. In this study, we investigated the role of a unique composition of Viola yedoensis extract for its ability to activate CD44, a cell-surface receptor of hyaluronic acid, and aquaporin-3, a water-transporting protein, in human keratinocytes (HaCaT). An ELISA assay evaluating the protein expression levels of CD44, aquaporin-3 (AQP3), filaggrin, and keratin-10 revealed that V. yedoensis extract upregulated the levels of CD44 and AQP3 by 15% and 78%, respectively. Additionally, V. yedoensis extract demonstrated a comparative effect on water vapor flux in TEWL and lipid perturbation in DSC versus the reference, glycerin. In light of this new biological efficacy, a detailed phytochemical characterization was undertaken using an integrated LC-HRMS/MS-based metabolomics approach, which provided further insights on the chemistry of V. yedoensis. This led to the identification of 29 secondary metabolites, 14 of which are reported here for the first time, including esculetin, aesculin, apigenin and kaempferol C-glycosides, megastigmane glycosides, roseoside, platanionoside B, and an eriojaposide B isomer, along with the rare, calenduloside F and esculetin diglucoside, which are reported for the first time from the genus, Viola. Notably, two active components identified in the V. yedoensis extract, namely, aesculin and schaftoside, showed an upregulation of the protein expression of CD44 in HaCaT cells by 123% and 193% within 24 h of treatment, respectively, while aesculin increased AQP3 levels by 46%. Aesculin and schaftoside also significantly upregulated the expression of K-10 levels by 299% and 116%, which was considerably higher than sodium hyaluronate, the positive control. The rationale used to characterize the new structures is outlined along with the related biosynthetic pathways envisioned to generate roseoside and Eriojaposide B. These findings provide new molecular insights to deepen the understanding of how V. yedoensis extract, along with the biomarkers aesculin and schaftoside, restores the skin barrier and skin hydration benefits.

In order to valorize natural resources and the traditional use of medicinal plants in Algeria, this study exploits the antibacterial effect of Carthamus caeruleus L. Since there are few studies on this plant despite its notable therapeutic potential, this work aims to characterize the chemical composition of Carthamus caeruleus L. leaf and root aqueous extracts and to evaluate their antibacterial activity through an in vitro and in silico studies. Spectrophotometric assays and HPLC results revealed 22 components in the roots and 16 in the leaves. Disc diffusion and microdilution methods were used to study the antibacterial properties against nine standard bacterial strains. The results showed that roots exhibited the best activity on most tested strains. Both extracts were also able to inhibit the growth of Staphylococcus aureus ATCC 25923 and Escherichia coli ATSC 25922. Furthermore, no nucleic acid leakage or membrane damage was detected. However, molecular docking of the molecules indicates that some constituents have significant affinity and stability for DNA gyrase. Gallic acid, luteolin, myricetin, and orientin were found to have the highest score. The molecular docking data suggest, for the first time, that the antibacterial activity may be caused by the inhibition of DNA gyrase.

Phytochemical characterization, toxicity and pharmacological profile of the central effects of the fixed fruit pulp oil of Mauritia flexuosa L.F. (buriti)

Anxiety and depression are mental disorders that have been exponentially increasing over the last decades. Psychopharmacology emerged to try to alleviate the symptoms of these disorders; however, the side effects and the time it takes to achieve the desired effect are factors that decrease the search for and adherence to treatment. To remedy this situation, new compounds capable of improving the performance of these medications and reducing their adverse effects have been sought. The use of medicinal plants has been widely employed for this purpose. Mauritia flexuosa F.L., a palm tree with high incidence in Brazil, has been heavily targeted as all its parts are usable. The objective of this study is to evaluate the effects of fixed oil from the fruit of the buriti palm in models of depression and anxiety. The phytochemical profile of this oil and its toxicity were also investigated. The experiments conducted included the open field, rotarod, forced swim, and elevated plus maze tests. As a result, it was observed that the fixed oil from buriti palm presented 18 compounds, with elaidic acid being the major one, and showed no signs of toxicity. However, it demonstrated a possible stimulating activity in the open field test and had no effect on the motor system in the rotarod test. Furthermore, it exhibited an antidepressant-like effect in the forced swim test but an anxiety-like effect in the elevated plus maze test. Therefore, buriti oil may potentially be used in new formulations to assist in the treatment of anxiety and depression.

Corema album Berry Juice as a Protective Agent Against Neurodegeneration.

Background/Objectives: Corema album berries are edible fruits from the Iberian Atlantic coast, characterized by a rich polyphenolic composition, which endows their juice with potential protective effects against neurodegeneration. This study aimed to evaluate the potential of the relatively lesser-known C. album berries as a novel neuroprotective agent against neurodegenerative diseases. Methods: The phenolic compounds of the juice were characterized using UHPLC-HRMS (Orbitrap). The SH-SY5Y neuroblastoma line was used to determine the preventive effect of the juice against H2O2-induced oxidative stress. Furthermore, neuronal cells were differentiated into dopaminergic and cholinergic lines and exposed to 6-hydroxydopamine and okadaic acid, respectively, to simulate in vitro models of Parkinson's disease and Alzheimer's disease. The ability of the juice to enhance neuronal viability under toxic conditions was examined. Additionally, its inhibitory effects on neuroprotective-related enzymes, including MAO-A and MAO-B, were assessed in vitro. Results: Phytochemical characterization reveals that 5-O-caffeoylquinic acid constitutes 80% of the total phenolic compounds. Higher concentrations of the juice effectively protected both differentiated and undifferentiated SH-SY5Y cells from H2O2-induced oxidative damage, reducing oxidative stress by approximately 20% and suggesting a dose-dependent mechanism. Moreover, the presence of the juice significantly enhanced the viability of dopaminergic and cholinergic cells exposed to neurotoxic agents. In vitro, the juice inhibited the activity of MAO-A (IC50 = 87.21 µg/mL) and MAO-B (IC50 = 56.50 µg/mL). Conclusions: While these findings highlight C. album berries as a promising neuroprotective agent, further research is required to elucidate its neuroprotective mechanisms in cell and animal models and, ultimately, in human trials.

Genetic and phytochemical evaluation of M2 generation mutants of fenugreek (Trigonella foenum-graecum L.) induced by gamma rays and Ethyl Methane Sulphonate (EMS).

Fenugreek (Trigonella foenum-graecum L.) is highly esteemed for its therapeutic properties and is widely used in traditional medicine and modern pharmacology. Enhancing its genetic traits and phytochemical profile, particularly its trigonelline content, can significantly increase its medicinal and agricultural value. This study aims to investigate the effects of gamma rays and Ethyl Methane Sulphonate (EMS) as mutagenic agents on the genetic and phytochemical characteristics of the M2 generation of fenugreek, focusing on genetic diversity and desirable trait enhancement. To achieve this, various concentrations of EMS and gamma rays were administered to fenugreek seeds, and 27 traits were assessed in the resulting M2 generation. These traits were analyzed for variance, mean values, and correlations. The genetic diversity of 23 M2 offspring was investigated using nine Start Codon Targeted (SCoT) markers. The genetic diversity assessment involved Principal Coordinate Analysis (PCoA) and cluster analysis, utilizing the Dice similarity coefficients and the Unweighted Pair Group Method with Arithmetic Mean (UPGMA). A Bayesian model provided deeper insights into the genetic structure. Results revealed that lower doses of gamma rays (100Gy) and EMS (0.2%) positively impacted specific traits. In comparison, higher doses (200Gy and 0.4% EMS) increased seed trigonelline content to 0.71mg/g dry weight. Among the SCoT markers, SCoT-9 was the most efficient, segregating the populations into three clusters. The first three principal components in the PCoA explained 20% of the total variance, leading to seven subgroup populations distinction. These findings underscore the potential of induced mutagenesis in enhancing desirable traits in fenugreek.

Exploitation of red beet peel powder as a natural food ingredient in whey-fruit based beverage

ABSTRACT Scientists and food producers are studying the potential of utilizing different by-products as highly nutritious food components to meet consumers’ growing demand for healthier and natural goods. Beetroot belongs to the Amaranthaceae family and is highly rich in antioxidants, specifically phenolics and betalains with excellent health properties. The peel of red beetroot, which is generally discarded, has a high concentration of bioactive phytochemicals (betalains, dietary fibers). These compounds are well-known for their strong antioxidant effects, improving cardiovascular health, reducing oxidative stress, and enhancing immunological function. Incorporating red beetroot peel (RBP) powder into whey-fruit-based beverages is a promising method to improve nutritional content and sensory attractiveness. This study investigated the influence of adding RBP to whey-fruit-based beverages, specifically examining its effects on physicochemical and phytochemical characteristics, antioxidant capacity, color, microbiological, and rheological attributes, and consumer preference. The RBP extract exhibited high amounts of total polyphenols (1239.35 ± 0.51 mg GAE/100 g dw) and antioxidant activity (90.02 ± 0.22%). The findings indicated that RBP had a notable impact on the antioxidant capacity (16.38 ± 0.37 μmol TE/g dw for BRBP1, 26.69 ± 0.10 μmol TE/g dw for BRBP3, 36.75 ± 0.31 μmol TE/g dw for BRBP6) of the beverages and enhanced their color without negatively impacting their sensory characteristics. The dynamic oscillatory rheological measurements revealed that beverage supplementation with increasing amounts of RBP obtained stronger networks with solid-like viscoelastic behavior. Using RBP powder as a natural food ingredient in whey-fruit-based beverages enhances their nutritional value and promotes sustainable food processing by making use of by-products from the food industry into innovative food options.

Various parts of these species are widely used in traditional medicine, especially pinecones, which are a significant source of bioactive compounds. The current study aimed to evaluate the phytochemical composition and biological properties of the aqueous extracts obtained by maceration from three Pinus petal fractions, from P. halepensis Mill., P. brutia Ten., and P. pinea L. (APW, BPW, and PPW respectively), and the core fractions of the same species (ACW, BCW, and PCW respectively). The results showed that APW demonstrated superior performance compared to other species and fractions (p ≤ 0.05), with the highest total polyphenol content (203.51 mg GAE/g DW) and the highest antioxidant potential (IC50 = 13.51 µg/mL) against DPPH free radical. All extracts showed high anticancer activity against HeLa and HepG2 cancer cell lines, and low inhibition against HEK-293, a normal cell line (<15%), indicating that none of extracts have any toxicity effect. Furthermore, only APW exhibits a significant inhibition against α-glucosidase with 77.20% at 50 µg/mL. HPLC-DAD analysis was conducted to identify 14 compounds. GC-MS analysis was conducted to identify 28 compounds, of which 11 were detected for the first time in this species. This study offers valuable insights into phytochemistry and potential therapeutic applications of pinecones.

“Deterioration” and “aging” can modify or breakdown the phytochemical and biochemical characteristics of green cumin (Cuminum cyminum L.), although their effects differ

Deterioration of medicinal plant and herb's spices seeds has two important aspects; its impact on viability and its influence on food and medicine feedstock. So, in this study was investigated of phytochemical and biochemical composition of green cumin (Cuminum cyminum L.) were evaluated under natural seed storage (NSS) for one and two years and accelerated seed aging process (ASA) for 24, 48, 72 and 96h. Oil percent declined by prolonging ageing duration. The highest amount was measured in control (21.60 %) and the lowest amounts in 2Y NSS (17.83 %) and 96h ASA (15.83 %). There was no significant difference among all treatments in unsaturated fatty acids (USFA) terms, yet percent of saturated fatty acids (SFA) rose by severe ageing condition. Among fatty acids, NSS had a strong correlation with oleic acid (C18:1) (R2 = 0.99 %), while ASA was correlation with stearic acid (C18:0) (R2 = 84 %). Total phenolic content, and under severe ageing were found in cumin. In the oil and essential oil (EO), DPPH showed an ascending trend in NSS treatments and a descending trend in ASA treatments. Additionally, the maximum IC50 was observed in the oil treatment, being approximately 8.6 times higher than that of the EO. 85 %–90 % of the EO compounds present in all treatments consisted of Myrcene, p-Cymene, Cumin aldehyde, and γ-Terpinene-7-al. NSS led to a significant increase in Cumin aldehyde (R2 = 0.99), indicating that enhancing the aroma of green cumin is subject to a period of cumin fruit storage. Finally, it is concluded that ASA can simulate NSS induced changes in oil content, EO components and antioxidant capacity.
