Figure 3From: Isorhamnetin 3-O-robinobioside from Nitraria retusa leaves enhance antioxidant and antigenotoxic activity in human chronic myelogenous leukemia cell line K562 a. Cellular Antioxidant Activity (CAA) of ethyl acetate extract (EA extract) K562 treated cells + 2 ′, 7′-dichlorofluorescin (DCFH) + 2,2′-azobis (2-amidinopropane) dihydrochloride (ABAP). PC: Untreated cells + 2 ′, 7′-dichlorofluorescin (DCFH) + 2,2′-azobis (2-amidinopropane) dihydrochloride (ABAP). b. Dose–response curve for the inhibition of oxidation of the free-radical 2 ′, 7′-dichlorofluorescin (DCFH) to DCF in K562 cells using the cellular antioxidant activity assay in the presence of different concentrations of ethyl acetate extract (EA extract) (mean ± SD, n = 3).Back to article page
