title: [The preliminary studies on antioxidation of three kinds of flavoniods from Litsea coreana].
abstract: In this paper, the antioxidation of three flavoniods from the leaves of Litsea coreana was tested by tissue homogenate MDA. The results showed that these compounds had the obvious effect of antioxidations with dose-effect relationship. And the activity is kaempferol > querctin-3-O-beta-D-glucopyranoside > kaempferol-3-O-beta-D-glucopyranoside. Another, by comparison of the inhibitory rate of tissue homogenate MDA of heart, brain, liver and kidney, it was found that their effect is kidney > heart > liver > brain. This paper may provide some important scientific informations for the development and utilization of natural antioxidants--three flavoniods from the leaves of Litsea coreana.
