Antioxidant activity of silver nanoparticles synthesized from crud methanolic extract of rumex nervosus

Abstract

In the present investigation, an attempt was made to prepare nanoparticles by using a medicinal plant Rumex nervosus, because the biological synthesized nanoparticles have been widely used in the field of medicine now. Silver sulfate (Ag2SO4) was used for the synthesis of the silver nanoparticles using the root extract of Rumex nervosus. The synthesized silver nanoparticles from silver sulfate solution through the root extract were characterized using UV-vis spectrophotometry, SEM, and FT-IR methods. The SEM analysis showed the average size of 75 nm with spherical shape and it confirmed the formation of nanoparticles in the sample. Antioxidant activity of the crude extract was evaluated by employing the DPPH radical scavenging assay. The result showed moderate antioxidant activity at various concentration as compared to standard ascorbic acid solution. The synthesized nanoparticles can be used for various applications due to its eco-friendless, nontoxic and compatibility for pharmaceutical and other applications.
