In the present study, an environmentally benign process of synthesis of the silver nanoparticles (Ag NPs) using Artocarpus Heterophyllus (Jack Fruit Leaves) as both stabilizing and reducing agents. The nanoparticles formation was observed by color change from pale yellow to dark brown. The effect concentration ratio of leaves extract intake and of silver nitrate solution on synthesis of Ag NPs was studied. The synthesized nanoparticles are characterized by XRD, SEM and FTIR techniques to analyze size, morphology and functional groups. The formation of silver nanoparticles was confirmed from UV spectroscopic technique. The crystallographic structure of synthesized Ag NPs was recognized using powder XRD technique. The presences of organic and inorganic compounds in synthesized nanoparticles were identified using FTIR analysis. The average size of synthesized nanoparticles was estimated using XRD patterns and SEM analysis.
