Ecofriendly Synthesis of Silver Nanoparticles Using Ethno Medicinal Plant Leaf Extract ( Jasminum auriculatum) and their Antibacterial Properties

Abstract

The present investigation, we describe a cost effective biofabrication of silver nanoparticles using jasminum auriculatum leaf extract. The aqueous leaf extract of jasminum auriculatum are used as reducing agent and capping agent in silver nanoparticles synthesis. The biofabricated silver nanoparticles were characterized by UV-Visible spectrophotometer, X-Ray Diffraction, FTIR spectra and SEM with EDX analysis. FTIR studies revealed that the functional group responsible for silver reduction were found to be jasminol and triterpinoid compounds present in leaf extract. XRD analysis showed that prepared silver nanoparticles are crystalline in nature with an average diameter of 15-20 nm. The prepared silver nanoparticles have been evaluated in vitro for antibacterial activities and found to have higher antibacterial activities.
