Green synthesis of Mangifera indica silver nanoparticles and its analysis using Fourier transform infrared and scanning electron microscopy

Abstract

Background: Cost effective and environmentally favorable green synthesis of metallic nanoparticles is a fast growing research in nanotechnology. Aims and Objectives: The present study reports the synthesis of silver nanoparticle (AgNP) using Mangifera indica leaves extract, and its constituents and particle size was analyzed by Fourier transform infrared (FTIR) spectroscopy and scanning electron microscopy (SEM). Materials and Methods: Preliminary phytochemical analysis of M. indica leaves extract was performed, and AgNPs were prepared by M. indica leaves extract when treated with silver nitrate. Finally, various functional groups in the plant extracts and size of the AgNPs were identified by FTIR and SEM analysis. Results: Qualitative phytochemical analysis revealed the presence of alkaloids, tannins, flavonoid, quinines, steroids, coumarins, and phenolic compounds in M. indica leaves extract. Presence of AgNPs in the green extract was confirmed by color changes from pale yellow to dark brown color and by an intense peak in the ultraviolet-spectrophotometer at 420 nm. FTIR analysis showed the presence of various functional groups between the frequency range of 400 and 4000/cm and SEM analysis showed the nanometer size of silver particles that formed. Conclusion: This novel green approach may be used for large scale production of metallic nanoparticle and can be used in pharmacological aspects based on the medicinal uses of M. indica.
