Nowadays, for green synthesis, different parts of plant extracts are being used for the synthesis of metallic nanoparticles. Green routes for the synthesis of metallic nanoparticles are most favorable method over conventional methods. In this study, we have synthesized Ag nanoparticles from Terminalia bellirica aqueous leaves extract with AgNO3 solution. Recently, silver nanoparticles are being used for their beneficial effects on human health. It has been reported that it helps in lowering in cholesterol, blood pressure, thirst, pile, skin diseases and treatment of diabetes. Ag nanoparticles were characterized by UV-Vis spectrophotometer, XRD, TEM and FTIR techniques. It was found that Ag+ ion reduced into Ag0 and showed absorption band at 447 nm. X-Ray Diffraction for structural determination confirms the crystalline Ag nanoparticles. TEM analysis confirms the average particle size is less than 30 nm with spherical shape. FTIR spectra confirms the presence of active biomolecules (alcohols, phenols, proteins and nitro compounds) of plant leaves extract which played a key role in formation of Ag nanoparticles.
