Abstract

Metal-plant extract nanoparticles have gained tremendous attention over the last decade due to their application in medical. In this study, green synthesis of chromium-Alstonei boonei nanoparticles was achieved. The leaves extract of Alstonia boonei and synthesized Cr3+- Alstonia boonei were characterized by UV-Vis absorption spectroscopy, Fourier Transform Infrared Spectroscopy (FTIR). Scanning Electron Microscopy (SEM), GC-MS spectroscopy and Xray diffraction spectroscopy. The result revealed that CRNP has the absorption peak at 470nm and 490nm respectively. Functional groups present on the CrNPs are band which makes it naturally stable. X-ray diffraction analysis revealed that the synthesized CrNP has an average particle size of 89.81nm and SEM micrograph showed aggregated irregular shapes with rough surfaces. The result of GC-MS study revealed phytochemical constituents of medical importance. The results of the present study showed that synthesized CrNP is naturally stable with phytochemical compounds that can be used in various biological applications.
