摘要：

The hexane. ethylacetate. n-butanol, and water extracts of 10 Korean herbal medicines were screened and compared for their antioxidant activities in a range of lipid peroxidation system using rat brain homogenates, antihemolysis assay of red blood cells, and other in vitro assays to determine their ability to scavenge superoxide and hydroxyl radicals. All of the 10 Korean herbal medicines have potent antioxidant activities. Among the four solvent extracts, the antioxidant activities of more-polar solvent extracts (BuOH and water extracts) were relatively higher than that of non-polar solvent extracts (hexane and EtOAC extracts). These results will be useful to further analyze those herbal medicines that contain the most antioxidant activity in order to identify the active principles. (C) 2003 Elsevier Science Ireland Ltd.
