Abstract: Ecofriendly approach towards development of nanoparticles (AgNPs) has more advantages because they are safely handling and easily available. The present work of green synthesis of silver nanoparticles (AgNPs) using Mentha asiatica (Mint) extract and checked their antioxidant activity. Silver nanoparticles were synthesized by the bioreduction of silver nitrate (AgNO3) by using different concentrations ofMint extract, and UV–visible spectral analysis and showed silver surface plasmon resonance band in the range of 200-800 nm to confirm the formation of silver nanoparticles. The presence of various Phytoconstituents like carotenoids and polyphenols, which include phenolic acids, flavonoids, and stilbenes, was investigated by using standard biochemical methods. After that the antioxidant activity was per formed by the DPPH method, and the ethanolic leaf extract of Menthaasi aticawas found to show significant antioxidant activity. The synthesized silver nanoparticles were characterized by scanning electron microscopy (SEM).
