This study was to investigate an efficient and sustainable route of AgNP preparation from AgNO3 using flower extracts of Erythrina indica. The AgNPs were characterized by UV-visible (vis) spectrophotometer, scanning electron microscopy (SEM). Fourier transform infrared spectrometer (FTIR) analysis was carried out to determine the nature of the capping agents in each of these flower extracts. The green synthesis method is eco-friendly, of low cost and capable of producing AgNPs at room temperature. Here, Erythrina indica flower extract used as both reducing and stabilizing agents. The AgNPs were characterized by UV–Vis, FTIR and SEM analysis. The UV–Vis spectral studies confirmed the surface plasmon resonance of green-synthesized silver nanoparticles. Biomolecules were responsible for reducing and capping of AgNPs, which were confirmed by FTIR measurements. SEM studies revealed spherical and uniform-shaped silver nanoparticles with size in the range 10–40 nm. In this present study, flavonoids in the Erythrina indica flower extract play an important role in the formation of silver nanoparticles.
