Studies on the Nepese 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.
