Protective effect of xanthones III and V on bovine serum albumin (BSA) oxidation induced by an OH generation system. a) Representative Coomassie blue-stained-BSA gel is shown. Different concentrations (0.5, 1 and 2.5 μM) of xanthones III (X-III) and V (X-V) and α-mangostin (M) were tested in OH generator system. b) Quantitative representation of the BSA detection. c) Representative Coomassie blue-stained-BSA gel is shown. Lane 1, BSA; lane 2, OH + BSA; lane 3, EtOH (0.01%) + BSA + OH; lanes 4, 5 and 6, xanthones III, V and α-mangostin (2.5 μM) respectively. + BSA + OH. Data are presented as mean ± S.E.M. of 4 independent experiments. aP < 0.01 vs. Control (C), bP < 0.01 vs. BSA + OH, cP < 0.01 vs. α-mangostin.
