In this study capability of plant extract such as Allium cepa and Mentha piperita for synthesis of silver nano particles was evaluated. Samples showed change in colour from almost pale yellow to brown, which indicate the formation of silver nanoparticles in the reaction mixture. The appearance of brown colour was due to the excitation of surface Plasmon vibrations, while control showed no colour change when incubated in the same condition. The highest absorbance was recorded 1.70 of Allium cepa and 1.84 of Mentha piperita at 413 nm wavelength.
