The present work was carried out to the chracterization and the evaluation of antimicrobial and anti-oxidant activity of Vn-ZnO NPs. The present research work focussed on the biosynthesized ZnO NPs by sodium hydroxide, zinc acetate and bio components of leaves of Vitex negundo in the reaction mixture was monitored in the precipitate from, which proved the formation of ZnO NPs. The biosynthesized nanoparticles were characterized by advanced tool viz. UV-Vis spectrophtometer, FT-IR, Particle size and zeta potential, X-ray diffraction and TEM along with EDAX. The UV-Vis peak was aquiered at 375nm. The zeta average 28 nm and the zeta potential value was -16.3mV.The average size of the nanoparticles was 34.46 nm and the minimum sized NPs read 16.2 nm by HR-TEM. Antibacterial activity of Vn-ZnO NPs was evaluated by examine against selected two gram negative (Escherichia coli, Salmonella typhi) and gram positive bacteria (Bacillus subtilis, Staphylococcus aureus). Antimicrobial activity of Vn-ZnO NPs was found to be more suceptable to the against gram negative bacteria. Strong DPPH activity was found by the Vn-ZnO NPs.

Keywords: Vitex negundo,HR-TEM, Vn-ZnO NPs, Antibacterial activity, DPPH activity
