Biological Activities and Characterization of Silver Nanoparticles from Prunus Prescia (L.) Batsch

In this paper, Prunus persica L. Batsch (wild and variety) plants have been used for the bioreduction of silver ions to silver nanoparticles. Aqueous leaf extract of plants was treated with silver nitrate. The mixture's color changed from pale yellow to dark brown Prunus persica (variety) and dark yellow to greyish brown Prunus persica (wild). The color change was the first indication of silver nanoparticle synthesis, further confirmed by UV-Vis spectroscopy. The surface Plasmon band exhibited absorption peaks for Prunus persica wild and variety leaf extract at 468 nm, 492 nm, 462 nm. The silver nanoparticles were further characterized using X-Ray Diffraction that carried out the crystallographic nature by exhibiting 2θ value from 10˚ to 90˚ corresponding diffraction planes of Face Centered Cubic structure. Fourier Transform Infrared spectroscopy demonstrated organic compounds in plant material that mainly involved in reduction. Prunus persica L. Batsch (wild and variety) mediated silver nanoparticles exhibited excellent antibacterial activity against a human bacterial pathogen. The antioxidant activity was also studied that showed effective results on synthesized silver nanoparticles using the 1, 1-Diphenyl-2-picrylhydrazyl (DPPH) radical scavenging assay. The result showed that Prunus persica L. Batsch proved to be a useful silver nanoparticle.
