Abstract

The use of plant extract to synthesize nanoparticles has transformed the area of nanotechnology. Silver nanoparticles (AgNPs) were generated in this work using the leaves of Cocculus pendulus as a reducing and stabilizing agent. The extract of C. pendulus was analyzed using a gas chromatography-mass spectrometer. UV-visible spectroscopy (UV-visible), Fourier Transform Infrared, Zeta potential, and Transmission Electron Microscopy were used to analyze the bio-fabricated AgNPs. In addition, we describe the antibacterial and antioxidant characteristics of AgNPs produced. Analyses were used to describe the morphology of produced AgNPs, which had a typical size of 45 nm. AgNP was discovered to be extremely poisonous to gram-positive bacteria and was a promising antibiotic against bacterial infections. Furthermore, antioxidant assays revealed the greatest free radical scavenging activity. Finally, our findings show that C. pendulus can be used as a source for green synthesis of AgNPs with strong antioxidant and antibacterial properties in vitro.
