Enriched… Expand Summary The antiperoxidative action of silymarin has been compared to that of quercetin, dihydroquercetin and quercitrin in… Expand 1. Dihydroxyfumarate slowly autoxidizes at pH6. This reaction is inhibited by superoxide dismutase but not by EDTA. Mn2… Expand Abstract The toxic action of the superoxide anion (O2−) toward the erythrocyte was investigated with O2− generated through the… Expand
