a. Cellular Antioxidant Activity (CAA) of isorhamnetin-3- o - robinobioside (I3- O -Rob) 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 concentration of isorhamnetin-3- o-robinobioside (I3- O-Rob) of Nitraria retusa (mean ± SD, n = 3).
