EXTRACT MANGIFERA INDICA PARTS TO STUDY THE GREEN SYNTHESIS OF SILVER NANOPARTICLES

Abstract

The green synthesis silver nanoparticles has main significance in the modern research evolution due to the antimicrobial ability of biosynthesized silver nanoparticles to compared to using of plant extract alone  . In recent study, the silver nanoparticles were green synthesized using Mangifera indica leaves and peels extracts separately and the biological inhibitory effect of biosynthesized silver nanoparticles were investigated using agar diffusion methods against (Staphylococcus aureus, proteus sp., Pseudomonas aeruginosa, E. coli, Serriatia sp., and Candida albicans), also the ability of biosynthesized silver nanoparticles against the selective bacterial and fungal isolates were studied and compared with  amoxicillin. The characterization of biosynthesized silver nanoparticles were indicated by changing the color of solution to reddish brown. UV-vis spectroscopy conformed the formation of the nanoparticles due to present the significant beak at 450 nm. The absorption beak was detected by FT-IR spectrum at 685.46 cm^-1. While the Scan Electron Microscope analysis (SEM) was fixing the size at 35nm to biosynthesized silver nanoparticles by leaves extract and 29nm to silver nanoparticles by peel extract.

The outcomes measured significant effect at different concentrations to biosynthesized silver nanoparticles, plants extracts. The results showed potent effect to silver nanoparticles by peels extract with inhibition zone ranged between 15-45 mm. The silver nanoparticles by leaves extract reveled remarkable inhibitory effect with 11-42mm inhibition zone, while the amoxicillin fail to inhabit the growth of Staphylococcus aureus, Serriatia sp. and Candida albicans. The findings of the present study focused on the ability of using biosynthesized Ag-NPs as altar choice in many medical and biomedical application particularly in treating many bacterial and fungal infection.
