• 論文の詳細を見る

• Four new flavanones (I-IV) and a new chalcone (V) were isolated from the root of Scutellaria discolor COLEBR., together with wogonin, norwogonin, 5,7,2'-trihydroxy-8-methoxyflavone, 5,7-dihydroxy-8,2'-dimethoxyflavone and wogonin 7-O-glucuronide. The structures of I-V were shown to be 2 (S)-5,7-dihydroxy-8,2'-dimethoxyflavanone, 2 (S)-7-hydroxy-5,8,2'-trimethoxyflavanone, (±)-5,2'-dihydroxy-7,8,6'-trimethoxyflavanone, (±)-5,2'-dihydroxy-6,7,6'-trimethoxyflavanone and 2', 4'-dihydroxy-2,3', 6'-trimethoxychalcone, respectively, based on spectral data and simple chemical modifications.
