Green Synthesized Gold Nanoparticle from Kigelia Africana Enhanced the Antibacterial and Antioxidant Activities: An In Vitro Approach

Medicinal plants are widely used by the Indian population since it has no harmful side effects and low cost compared to other treatments. In the 21st century, nanotechnology field is expected to be the base for all the important technological innovations. From that, green synthesis of gold nanoparticle is gaining more momentum due to its commercial demand besides it plays a significant role in the medical and biomedical applications. Spherical gold nanoparticles isolated from the leaf extract of Kigelia africana were studied by UV-visible spectroscopy. The green synthesized KaGNPs considerably exhibited strong radical scavenging potential (77.54 %) when compared to the aqueous leaf extract (66.09 %). Further KaGNPs inhibited the growth of human pathogens both Gram-positive and Gram-negative.
