A versatile technique was implemented for the synthesis of silver nanoparticle using aqueous extract of leaves of Gymnema sylvestre. The reduction of silver nitrate to silver nanoparticle was confirmed by UV-Vis spectrophotometer showing a typical resonance (SPR) at about 390nm which is specific for ag NPs. In FT-IR analysis the strong band peak at 3355cm-1 in aqueous extract is vibration bands, which may be due to overlapping of amine N- H stretching bands. HR-SEM images reveal that the particles are spherical and relatively uniform shape of the silver nanoparticles was confirmed in the range of 30- 50nm in aqueous extract, whereas DLS shown good zeta potential and less particle size finally silver nanoparticle using aqueous extract of leaves of Gymnema sylvestre shown very high antimicrobial activity.
