Antimicrobial activity of silver Nanoparticles using leaves extract of Alstonia scholaris

Abstract

The present study is an attempt to test the antibacterial efficacy of SNPs produced by using the leaf extract of Alstonia scholaris, which have been using in traditional medicine without any validation. Plant extract of Alstonia scholaris was prepared. Then silver nanoparticle was prepared using AgNO3. The antimicrobial activity of the nanoparticles was demonstrated against both gram positive and gram negative bacteria. The study indicates that gram positive bacteria are relatively resistant to the bactericidal action of silver nanoparticles than gram negative bacteria. Thus present study confirms the use of Alstonia scholaris plant for biosynthesis of silver nanoparticles and its potential use against microbes.
