[Studies on the absorption kinetics of baicalin and baicalein in rats' stomachs and intestines].

Abstract

Baicalin is moderately absorbed in stomach and poorly in small intestine and colon; Baicalein is well absorbed in stomach and small intestine but worse in colon, suggesting that the former is more suitable to be administered orally. The extensive absorption segments of bacailein suggests that it can be processed into a sustained-release preparation.
