Abstract

Owing to their eco-friendliness and nontoxic nature, the green synthesis of metallic nanoparticles (NPs) has intrigued the scientific community. Additionally, plant extracts offer a valuable source of reductants and stabilizers for the production of these NPs. The current study used leaf extracts of Jasminum angustifolium for the green synthesis of silver nanoparticles (Ja-AgNPs). The characterization of these Ja-AgNPs was conducted utilizing ultraviolet-visible spectroscopy (UV-Vis), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR) and scanning electron microscopy (SEM). Analysis of FT-IR spectra revealed the acyclic alcohol functional groups presence as capping and reducing agents for the Ja-AgNPs. Furthermore, SEM analysis of the Ja-AgNPs revealed a size distribution of approximately 30 nm (diameter). Antimicrobial assays using log phase cultures of Staphylococcus aureus revealed zones of inhibition (ZOIs) with diameters of 1.16 ± 0.15 mm at 50 μg/mL and 1.56 ± 0.05 mm at 100 μg/mL Ja-AgNP. These results indicate that the biosynthesized Ja-AgNPs have promising antibacterial properties.
