Abstract: A new green methods for the synthesis and stabilization of silver nanoparticles (AgNPs) using water extract of Rhynchostylisretusa(L.) Blume leaf with the help of Sun light as a source of energy has been developed. As obtained, the nanoparticles are characterized by FTIR, UV-visible (UV-Vis), X-ray diffraction (XRD) and SEM-EDX analysis.Thus, crystalline nature of AgNPs is confirmedby the prominent peaks in the XRD pattern.Distinct diffraction peaks in XRD spectrum is noticed at around 38Ο, which are indexed by the (100) of the cubic face centered silver. FTIR spectrasuggest that the possible biomolecules are responsible for the efficient stabilization of the sample.The band between 3490-3500 cm-1corresponds to O-H stretching,H-bonded alcohols and phenols. The peak found at around 1450-1500 cm-1 showed the bond stretch for N-H. The prepared nanoparticles had different antibacterial activity on both gram positive and gram negative bacteria.
