In this study, the preparation of silver nanoparticles (Ag NPs) using Tribulus longipetalus Viv. leaf extract was evaluated. Additionally, the in vitro antioxidant and antibacterial activities of the extract were evaluated. The antioxidant activity was assessed by two different approaches based on 2,2-diphenyl-1-picryl-hydrazyl and reducing power assay. The antibacterial activity of the extract, on the other hand, was determined against gram positive and gram negative microorganisms. The AgNPs prepared under the optimal conditions were found to be 15 nm in size and were characterized by ultraviolet-visible spectroscopy, dynamic light scattering, X-ray diffraction and transmission electron microscopy.
