Studies on the Nepalese crude drugs. VI. On the flavonoid constituents of the root of Scutellaria discolor Colebr. (2).

Abstract

From the root of Scutellaria discolor COLEBR., two new flavones (I and II) were isolated together with pinocembrin, 7-hydroxy-5, 8-dimethoxyflavone, 5, 7, 4'-trihydroxy-8-methoxyflavone, 5, 7, 2'-trihydroxy-8, 6'-dimethoxyflavone and norwogonin 7-O-β-D-glucuronopyranoside. Compounds I and II were identified as 7-hydroxy-5, 8, 2'-trimethoxyflavone and 5, 7-dihydroxy-8, 2', 6'-trimethoxyflavone, respectively, based on spectral and chemical data.
