Abstract: Green synthesis of silver nanoparticles (AgNPs) has gained much interest from chemists and researchers. In this concern, Indian flora has yet to divulge innumerable sources of cost –effective non-hazardous reducing and stabilizing compounds utilized in preparing AgNPs. This study investigates an efficient and sustainable route of AgNP preparation from 1mM aqueous AgNO3 using flower extracts of Cajanus cajan Leguminosea family well adored for their wide availability and medicinal property. The AgNPs were characterization by UV-visible (Vis) spectrophotometer, Scanning electron microscopy (SEM). Fourier transform infrared spectrometer (FT-IR) analysis was carried out to determine the nature of the capping agents in each of these flower extracts. AgNPs obtained showed significantly higher antimicrobial activities against Staphylococcus aureus, and E.coli in comparison to both AgNO3 and raw plant extracts. In totality, the AgNPs prepared are safe to be discharged in the environment and possibility utilized in processes of pollution remediation, may also be efficiently utilized in agricultural research to obtain better health of crop plants as shown by our study.
