The aim of this study is to use the purslan (Portulacae oleracea L) leaves aqueous extract in order to prepare copper nanoparticles and to explore antioxidant and anti-inflammatory activity of aqueous extract of P.oleracea L and CuNPs. The nanoparticles were characterized from structural and morphological point of view by using analytical techniques such as: UV-Vis spectroscopy, Fourier Transform Infrared Spectroscopy (FTIR), and Scanning Electron Microscopy (SEM). Antioxidant activity of purslane and CuNPs was studied done FRAP assay also the anti-inflammatory and hemolysis essay were studies. The acute toxicity test was applied in Wistar albino rats. Obtain results show that the SEM analysis revealed that the particle size was found to be ranging under 46 nm. On the other hand, the copper nanoparticles and purslan possessed the reducing capacity when IC50 value was 68, 316 μg/ml and 79, 675 μg/ml respectively, the anti-inflammatory ability while IC50 value was 77, 503 μg/ml and 60, 727 μg/ml respectively. In this study, the toxicity test showed no mortality or behavioral change up to 20 mg/kg of albino Wistar rats CuNPs. We concluded that Portulaca oleracea L has potential properties as biocatalyst or natural stabilizers for CuNPs synthesis. Each CuNPs as P.oleracea L leaves extract were have a reducing and anti-inflammatory capacity which can be protect the cells against the degenerative effects of Reactive Oxygen Species (ROS).
