摘要: The antioxidant activity of extracts from bark and heartwood Acacia confusa was evaluated by various assays, including free radical superoxide scavenging assays lipid peroxidation assay as well hydroxyl radical-induced DNA strand scission assay. In addition, an ex vivo using a flow cytometric technique also employed in this study. results indicate that both clearly have strong effects. Similar inhibitory activities for each test sample were found 1,1-diphenyl-2-picrylhydrazyl (DPPH) generation peroxidation. As the activity, extract more effective than extract. Furthermore, protected ΦX174 supercoiled against induced ultraviolet photolysis H2O2, it reduced amounts intracellular hydrogen peroxide, reactive oxygen species, when co-incubated with human promy...
