Free radical is harmful to the living body it is unstable and donates to electron other molecules of living bodies. In everyone bodies, different types of free radicals are spread by exogenous and endogenous sources. Antioxidant molecules are inhibited to process of development free radical in bodies. At present two types of antioxidant uses as a drug, chemically synthesized in the lab and naturally plants develop as a secondary product. According to WHO (world health organization), plants are rich sources of natural products and secondary metabolites. Equisetum diffusum plants is a natural and virtuous source of antioxidant. The aim behind choosing this plant was that how much capacity this plant has to stop or eliminate free radicals. In all extracts of E. diffusum the best scavenging activity was carried out the inhibitory concentration of 50% (IC50) value 0.3525±0.006 mg/ml water extract compared to 0.7471±0.0053 mg/ml IC50 value of standard ascorbic acid because it is accomplished of dissolving maximum numbers of substances.

Keywords: free radical, scavenging, 2, 2-di¬phenyl-1-picrylhydrazyl, and E. diffusum.
