摘要

The recent research in nanoparticles synthesis field utilizes biological synthesis rather than chemical and physical methods in order to get uniform size and non-toxic of nanoparticles, further in biological synthesis the microbial synthesis is time consuming and requires sterilized conditions wherein green synthesis can overcome these drawbacks. The green synthesis of silver nanoparticles from many plant extracts finding quit attraction to many research scholars though very minute work has been done by using Hibiscus leaf extract. In this research work comparative experimental investigation is done on green synthesis of silver nanoparticles from three extracts Hibiscus leaf extract, followed by characterization was done by UV-Spectrophotometer, XRD, FTIR, AFM and SEM analysis. The silver nanoparticles of size 25-50 nm were synthesized by Hibiscus leaf extract. The silver nanoparticles were later treated with 4 different antibiotics wherein erythromycin showed three-fold increments in its efficiency.
