Synthesis of Silver Nanoparticles Using Reactive Water-Ethanol Extracts from Murraya paniculata.

Abstract

Using the radiation–chemical simulation method of free radical reactions with 2,2-diphenyl-1-picrylhydrazyl, we were able to show high antiradical activity of water–ethanol extracts from Murraya paniculata. This will allow for the creation of new bioactive antioxidants based on them. The formation of silver nanoparticles (Ag-NP) was determined using the silver-ion reduction process by M. paniculata extracts. A band of electronic plasmon resonance was identified in the optical absorption spectra of hydrosols of Ag-NP using extracts of dried M. paniculata leaves. A decrease in the number of Candida albicans and Pseudomonas aeruginosa cells after introduction into the Ag-NP system synthesized by the reduction of silver cations using M. paniculata extracts indicates their moderate antimicrobial activity.
