Silver and iron nanoparticles of the chloroform extract of Psephellus pyrrhoblepharus were prepared for this study by green synthesis method. The characterisation of the nanoparticles was carried out with some methods like the Fourier Transform Infrared Spectroscopy (FTIR), Transmission Electron Microscopy (TEM), Scanning Electron Microscopy (SEM), X-ray Diffraction Analysis (XRD), zeta potential and particle size. The antioxidant activities and total phenolic capacities of nanoparticles and three different extracts of P. pyrrhoblepharus (chloroform, methanol:water (1:1) and n-hexane) were compared. Silver nanoparticles were the most active ones by antioxidant activities and total phenolic capacity. Although the iron nanoparticles showed activity, they did not show a successful activity as silver nanoparticles. This research is essential because it contains the first nanoparticle studies prepared from the plant P. pyrrhoblepharus.eninfo:eu-repo/semantics/closedAccessPsephellus pyrrhoblepharusSilver nanoparticlesIron nanoparticlesAntioxidant assaysSesquiterpene LactonesArticle9828591WOS:0006702696000032-s2.0-85132632942Q4Q4
