Abstract

In this study, the antioxidant activity and green synthesis of silver nanoparticles of ethanolic extracted from the seeds of Bunium persicum (Boiss.) B.Fedtsch. was investigated for a first time. B.persicum is a local plant of Iran and the Study of antioxidant activity in this plant performed using DPPH method and shows the notable Results in scavenging the free radicals. Antioxidant activity of extract checked in comparison to BHT. IC50 of B.persicum respectively was 1000 mg/mL that reveals notable antioxidant effect. Another experiment performed on green synthesis of silver nanoparticles in this plant extract. Green synthesis of silver nanoparticles in B. persicum confirmed by the FT_IR, scanning electron microscopy (SEM) , UV-vis spectroscopy and EDX spectra . Ag NPs were almost spherical in shape with an average diameter of 51 nm. Results showed significant antioxidant effects that cause the formation of spherical silver nanoparticles with nearly homological size in this plant that can be used as the basis of medical studies in the future.
