Generation and Characterization of Silver Nanoparticles in Mentha pulegium Extract and Evaluation of Biological Activities of the Prepared Extract

The aim of the present study was to synthesize silver nanoparticles (AgNPs) using Saudi Mentha pulegium leaves, characterize physicochemical properties resulting AgNPs, and evaluate biological activities AgNP-containing extract. formation AgNPs in M. extract indicated by a change color following addition nitrate confirmed UV-visible spectroscopy with maximum absorbance at 425 nm. Energy dispersive X-ray (EDX) that anisotropic were spherical, Fourier transform infrared (FTIR) spectral analysis aqueous extracts responsible for reducing Ag+ Ag0. secondary metabolite contents methanolic corresponded 17 mg GAE/g DW. DPPH ABT radical-scavenging assays possessed antioxidant activity ( IC50=6 3 ?g/mL, respectively). Disc broth dilution revealed exerted significant antibacterial activity, inhibition zone diameters minimal concentrations 17–24 mm 0.08–0.62 mg/mL, respectively. These findings clearly indicate modified plant have high importance potential use as preservatives pharmaceutical food industries.
