Green Synthesis of Silver Nanoparticles from aqueous leaves extract of Hibiscus rosa-sinensis and its antioxidant activity

Dr. N. CHANDRA LEKHA, M. SELVIPRIYA

Abstract

The present study endeavour the synthesis of green silver nanoparticles (AgNPs) from the leaf extract of medicinally important herb, Hibiscus rosa-sinensis in vitro antioxidant activity. The formation of silver nanoparticles were confirmed  by the color change from green to dark brown and the absorption peak obtained in the range of 432nm using ultraviolet-visible(UV-Vis). From FTIR spectroscopy the various phytochemical compounds detected are known to beneficial importance in medicinal sciences. The AFM studies reported  the NPs are equal in size and their morphology also rough in nature . The biosynthesized Ag-NPs has been proven antioxidant activity.
