From the roots of Scutellaria baicalensis GEORGI, three new flavonoids, III, IV and V were isolated along with dihydrooroxylin A (I) and chrysin (II). The chemical structures of III, IV and V were established as 2', 5, 8-trihydroxy-7-methoxyflavone, 2', 5, 8-trihydroxy-6, 7-dimethoxyflavone and 4', 5, 7-trihydroxy-6-methoxyflavanone, respectively, by chemical and physical analyses.
