Abstract

An eco-friendly ethanolic extract of the Tridax procumbens plant is used in the manufacture of silver nanoparticle (AgNps), which are then examined using UV and other analytical methods. Silver nanoparticle are prepared and tested for biological activity by measuring the invitro anti-oxidant activity using ascorbic acid (vitamin C) and DPPH as standards, as well as the invitro anti-inflammatory activity using protein denaturation assay. The colour shift from colourless to reddish brown indicates the creation of silver nanoparticles during biosynthesis and peak absorption at 400-490 nm indicates AgNps generation. They showed significant anti-oxidant and antinflammatory properties when compared to standard under comparable condition. Thus in-vitro data are suitable for animal studies.
