Abstract
Green synthesis of gold, copper, and silver metal nanoparticles is currently growing research due to different medical applications. Necessary natural human health-protecting components can be derived using nanobiotechnology using plant extracts in biodiversity enriched countries. Silver nanoparticles have shown various biological applications such as antimicrobial, anticancer, and antidiabetic activities. Hence, this work studied the yield and antioxidant activity of silver nanoparticles derived from various solvent extracts of Simarouba glauca leaflike methanol, ethanol, chloroform, ethyl acetate, and water. The derived silver nanoparticles of various extracts were characterized by absorption and vibrational spectra. Out of the five extracts, high yield silver nanoparticles surface morphology was inspected by scanning electron microscope. Also, the prepared silver nanoparticle’s antioxidant activity was examined using the 2, 2’-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid assay protocol, and the results were compared for future work. From the results, this work observed that the silver nanoparticles of ethanol crude exposed 72% yield and 39% yield obtained from chloroform extract. The silver nanoparticles of methanol crude showed good antioxidant activity (IC50 = 16.59μg/ml) when compared to the other extract nanoparticles due to the phytochemicals concentration difference.
