Abstract
From the root of S. baicalensis Georgi, 3 new flavonoids, II, III and IV, were isolated, together with 5,7,2''-trihydroxyflavone (I) and baicalein-7-O-.beta.-D-glucopyranoside (V). The structures of II, III and IV were established as 5,7,2''-trihydroxy-8,6''-dimethoxyflavone, 5,7,2'',5''-tetrahydroxy-8,6''-dimethoxyflavone and 5,2'',5''-trihydroxy-6,7,8-trimethoxyflavone, respectively.Keywords
