title: [Study on flavonoids from stem bark of Pongamia pinnata].
abstract: Seven flavonoids, pongaflavone (1), karanjin (2), pongapin (3), pongachromene (4), 3,7-Dimethoxy-3', 4'-methylenedioxyflavone (5), millettocalyxin C( 6), 3,3',4', 7-tetramethoxyflavone (7), were isolated from 50% EtOH syrup of the bark of Pongamia pinnata and structureal elucidated on the base of spectral data. Compound 6 was isolated for first time from the plant of the genus Pongamia.
