From the aerial parts of Scutellaria discolor COLEBR., two new flavones (I and II) were isolated together with chrysin, wogonin, apigenin, luteolin, 5, 7-dihydroxy-8, 2'-dimethoxyflavone, 5, 7, 4'-trihydroy-8-methoxyflavone, 5, 7-dihydroxy-8, 2', 6'-trimethoxyflavone and chrysin 7-O-glucuronide. Compounds I and II were identified as 5, 7, 8-trihydroxyflavone 8-O-β-D-glucuronopyranoside and 5, 7, 2', 6'-tetrahydroxy-8-methoxyflavone 2'-O-β-D-(2-O-caffeoyl)glucopyranoside, based on spectral and chemical data.
