Abstract
The present study focuses on the biogenic
synthesis of Zinc Nanoparticles (Zn NPs) using an aqueous extract of Solanum
torvum leaves and evaluates their antioxidant, antimicrobial, and
anti-larvicidal activities. Zinc nanoparticles synthesized via the green
aqueous extract of Solanum torvum leaves exhibited notable antioxidant,
antimicrobial, and larvicidal activities. Antioxidant potential was evaluated
through multiple assays, demonstrating a remarkable increase in DPPH radical
scavenging, with efficiency rising from 20% at 100 µg/mL to 80% at 500 µg/mL,
alongside a significant elevation in FRAP values from 150 μmol Zn (II)/g
extract to 750 μmol Zn (II)/g extract. The antimicrobial efficacy of the
nanoparticles was evident, showing strong inhibitory effects against both
Bacteria and Fungi. Furthermore, the synthesized nanoparticles displayed a
concentration-dependent larvicidal activity against Culex quinquefasciatus,
achieving 100% mortality at 100 ppm after 72 hours. These promising results
highlight the potential of Solanum torvum-derived zinc nanoparticles for
diverse applications in environmental management and biomedical fields.
