Objective: To introduce a cost effective and eco-friendly technique of preparing silver nanoparticles (Ag NP) from the medicinal plant, Pithecellobium dulce.

Methods: Ag NP of different concentration was prepared and characterized by using UV-Vis Spectrophotometer, Transmission Electron Microscopy (TEM), Scanning Electron Microscopy, X-Ray Diffraction (XRD), and Fourier Transform Infra Red (FTIR).

Results: Studies by UV-Vis spectroscopy showed absorption spectra of silver nanoparticles at an absorbance peak at 475nm, in all the three different concentrations (1mM, 3mM and 5mM). The size of Ag NP ranged 50-70nm and appeared to be dominantly spherical (and occasionally triangular). The XRD pattern revealed that these silver nanoparticles have a crystalline nature.

Conclusion: These nanoparticles produced by green synthesis proved stable in solution and can have promising role in nano-medicine.
