Rhus vulgaris Meikle fruit-mediated silver nanoparticles: Synthesis, characterization, and potential for sun protection, antioxidant and antibacterial applications

PLoS ONE, Год журнала: 2025, Номер 20(5), С. e0324799 - e0324799

Опубликована: Май 22, 2025

This study investigates the synthesis of silver nanoparticles (AgNPs) using Rhus vulgaris fruit extract (RVFE) and evaluates their antioxidant, antibacterial, UV protection properties. R. , a member Anacardiaceae family, is known for its rich phytochemical profile, including phenols, glycosides, alkaloids, saponins, tannins, terpenoids, which contribute to medicinal The AgNPs were synthesized by mixing RVFE with nitrate (AgNO₃) under optimized conditions: temperature 80 °C, pH 9, reaction time 40 minutes, 9:1 AgNO₃-to-RVFE ratio. Characterization was performed UV-Vis spectroscopy, Fourier Transform Infrared (FTIR) Transmission Electron Microscopy (TEM), X-ray Diffraction (XRD), zeta potential analysis. results confirmed successful synthesis, exhibiting an average size approximately 14.64 ± 0.4 nm -26.0 mV, indicating good stability. antioxidant activity assessed DPPH radical scavenging assay, revealing maximum inhibition 53.7% 0.12% IC₅₀ value 81.2 μg/mL. Antibacterial tests demonstrated significant against various bacterial strains, zones ranging from 23.88 1.10 mm 30.21 1.21 mm, stronger effect Gram-negative bacteria. Additionally, exhibited high Sun Protection Factor (SPF) 234.5, suggesting as effective blockers.This highlights promising applications AgNPs-RVFE in biotechnology, medicine, healthcare, emphasizing eco-friendly biological activities.

Importance of conserving Vitex peduncularis: A depleting forest resource with immense ethnopharmacological uses

The Pharma Innovation, Год журнала: 2023, Номер 12(5), С. 119 - 125

Опубликована: Май 1, 2023

Vitex peduncularis, vernacularly known as ‘Charaigorwa’ is a large evergreen tree having numerous ethnopharmacological uses and belongs to the family Lamiaceae. The species globally for its usage cure multifarious human health issues in traditional well contemporary medicines. exerts high bioactivity due presence of several secondary metabolites, including flavonoids, Vitexin, iridoid glycosides, pachypodol, ursolic acid, 2-hydroxy-ursolic acid terpenoids. Due demands V. peduncularis pharmaceutical industries, being exploited indiscriminately, pushing it towards abyss extinction. Immediate conservation measures are required sustain available natural population through multidisciplinary scientific interventions. This article cumulates importance directing specialized pharmacological characteristics therapeutic uses. It also highlights research gaps needed be filled up judicial use conserving depleting genetic resources.

A Dual Approach by Nanostructured α‐Mangostin‐Copper Oxide Complexes Against Dental Pathogen Biofilms and Oral Cancer via Apoptosis Gene Modulation

Chemistry & Biodiversity, Год журнала: 2024, Номер unknown

Опубликована: Окт. 22, 2024

Abstract The development of effective treatments for dental pathogens and oral cancer remains a significant challenge. Copper oxide nanoparticles (CuO NPs) are recognized their strong antimicrobial properties, attributed to the synthesis oxygen‐dependent radicals. α‐Mangostin (MG), natural xanthone from mangosteen fruit, is well‐known its antioxidant, antimicrobial, anticancer potential. combination CuO NPs with MG would offer synergistic approach enhance therapeutic efficacy. CuO‐MG were synthesized characterized size, morphology, surface properties. efficacy these was tested against pathogens, including Staphylococcus aureus , Enterococcus faecalis Streptococcus mutans Candida albicans . Antioxidant activity assessed using superoxide anion hydroxyl radical anion. potential evaluated by examining apoptosis induction in cell lines, focusing on expression key apoptotic markers such as Caspase‐3, Caspase‐8, FasL. Molecular docking simulations performed understand interaction between biofilm receptors. evidenced all enhanced combined effects CuO‐induced oxidative stress properties MG. assays demonstrated dose‐dependent increase scavenging activity. In cells, significantly reduced viability induced apoptosis, up‐regulation studies revealed binding affinities receptors, disrupting pathogen adhesion formation. offers powerful multifaceted healthcare. demonstrate offering management infections cancer. Further preclinical clinical recommended ensure safety stability medical applications.
