The green synthesis process of silver nanoparticles (Ag NPs) by plant extract is simple, cost-effective, eco-friend and non-toxic. In the present investigation, the silver NPs were prepared from the leaf extract of Solanum surattense Burm F with different quantity. Ag NPs were attained within 1 h from the aqua solution of 1x10-3 M AgNO3 and leaf extract. Green synthesized Nanoparticles (NPs) has been analysed by UV-visible spectrum confirmed the react of silver NPs. XRD indicated that the crystalline structure of the silver NPs, The functional groups are alcohols, alkenes, primary amines, proteins and aliphatic amine compounds of leaf extract which are involved in the reduction of Ag+ ions were identified from the FT-IR spectrum. FE-SEM obtained by surface morphology mostly spherical shape. The TEM analysis informed the particle size is spherical in nature with its size distribution between 16 nm-32 nm. Thus, synthesized Ag NPs showed good free radical scavenging and excellent dye degradation activity, which was analysed by the sunlight irradiation method from S. surattense leaf extract.
