Abstract: Generally, nanoparticles are prepared by a variety of chemical methods which are not environmentally friendly. Use of plants in the synthesis of nanoparticles is quite novel leading to truly green chemistry which provided advancement over chemical and physical method as it is cost effective and environment friendly. We have reported a fast, convenient and extracellular method for the synthesis of silver nanoparticles by reducing silver nitrate with the help of fenugreek seeds (Trigonella Foenum Graecum) extract. The characterization of nanoparticles was done by using UV- Vis Spectrophotometer. The morphology of silver nanoparticles was confirmed by Scanning Electron microscopy (SEM) and X Ray Diffraction Analysis (XRD). The antibacterial activity of these nanoparticles were studied against E.coli, Streptococcus Pneumonia, Proteus Vulgaris, Pseudomonas Aeruginosa and Staphylococcus Aureus comparing with the standard drug Ampicilin.
