The present study was designated to study the antioxidant activity of aerial and root parts of Capparis spinosa L.. Total polyphenol content was determined, after extraction with solvents in five subfractions; methanol （CE）, Hexan （HE） chloroform （CHE）, ethyl acetate （EAE） and aqueous extracts （AE）, employing the ＂Prussian blue assay＂. The results showed that EAE containing the highest concentration of phenolic compounds and Flavonoids followed by those of CHE of aerial and root parts, repectively. The antioxidant protective effects of extracts were determined by measuring the erythrocyte membrane resistance to free radical-induced. The results demonstrated that all the extracts exhibited a protective effect against t-BHP induced oxidative damages in human erythrocytes, the most potents wer CEs and CHEs with 86.55%, 85.81%, 74.59%, and 68.70%, for aerial and root parts, respectively, which were more effective than used standards： Quercetin （65.46%） and rutin （59.62%）. In order to more clarify the previous antioxidants activity of the extracts through other mechanisms, the iron chelating ability assays were realized. The results showed that the iron chelating ability of Aerial and root extracts were very considerable; the CE showed an excellent chelating with ICs0 of 0.197 ± 0.031 μM/quercetin equivalent, higher than that used standard EDTA, with approximately 0.34 folds. These results show that Capparis spinosa L. extracts have strong anti-oxidant effects and may have some clinical benefits.展开更多
