Current study deals with the synthesis, and antioxidant activity of silver nanoparticles using aqueous extract of acacia catechu leave extract . The reaction mixture turned to brownish colour after 2 h of incubation and was confirmed by surface Plasmon spectra using UV-visible spectrophotometer around 490 nm characteristic of silver nanoparticles Nanoparticles have shown exceptional electronic, catalytic, optical, magnetic and other physical and chemical properties that are quite different from the bulk one. Silver nanoparticles have proven useful in antibacterial clothing, burn ointments and as coating for medical devices because of their mutation resistant antimicrobial activity. To fulfill the growing need of environmental friendly nanoparticles, researchers are using microorganisms for the synthesis of various silver nanoparticles ofhas been reported acacia catechu to possess antioxidant activity ..
