Abstract

Biological methods are less cumbersome and much ecofriendly and this paper reports the green synthesis of silver nanoparticles using the extract of Breynia retusa leaves extract. Biosynthesis of silver nanoparticles was assisted by microwave irradiation to minimize the time taken for the reduction of silver ions. The nanoparticles thus synthesized were subjected to physical characterization. The UVVisible spectra, Fourier Transform Infra-Red Spectroscopy spectra, Xray diffraction pattern were studied. The size and surface morphology of the nanoparticles were determined using Scanning Electron Microscopy. The silver nanoparticles were also analyzed for amylase inhibitory activity. The nanoparticles proved to be potential inhibitors of amylase and thus promising anti-diabetic agents.

Keywords: silver nanoparticles, Breynia retusa, XRD, FTIR, amylase inhibition, antidiabetic.
