Figure 7From: Antioxidant properties of xanthones from Calophyllum brasiliense: prevention of oxidative damage induced by FeSO4 Xanthone III decreased lipid peroxidation (LP) induce by FeSO 4 . Different concentrations of xanthone III (0.5, 1, 2.5 μM) were incubated in the presence of ferrous iron in a) forebrain, b) liver and c) kidney homogenates. Control is represented by 100%. Data are presented as mean values ± S.E.M. of six experiments per group. aP < 0.01 control; bP < 0.01 vs. FeSO4.Back to article page
