A range of methods is available for the synthesize nanoparticles. However, these methods are associated with the production of undesirable byproducts which are quite hazardous and high costs. Thus a number of efforts are being made to develop novel cost-effective safe & reliable "green" procedures which caned produce desired nanoparticles. In this study, we caned successfully develop a green synthesis method for preparation of silver nanoparticles using Desmodium gangeticum leaf extract as reducing & capping agents. The method was found a quite effective inversion of silver ions to silver nanoparticles in a short interval of time. The developed nanoparticles exhibited Surface plasmon resonance at around 500 nm. The particles are nearly spherical, and the size ranged between 16-64nm. The average size was noted to be around 40 nm. The nanoparticles were characterized for their morphology using UV-vis, TEM, FTIR analysis and FESEM. The developed method carries the advantage of the completion of the reaction in a short time. The crystalline nature of the synthesize nanoparticles was assessed & confirm by XRD & EDX Studies. From FTIR studies, it can be understood that the flavonoids could be adsorbed on the metal surface by interaction with carbonyl groups. The process was carried out in the environment-friendly condition.
