Studies on the Constituents of Guang-Dou-Gen (the Root of Sophora subprostrata CHUN et T.CHEN). (6). Isolation of Two New Flavanones

Two new flavanones were isolated from Guang-Dou-Gen (the root of Sophora subprostrata CHUN et T.CHEN) and their structures were established from their spectral data and comparison with the corresponding synthesized derivatives as 4', 7-dihydroxy-6, 8-bis(3-methyl-2-butenyl)flavanone (I), and 2-...

Zusammenfassung:Two new flavanones were isolated from Guang-Dou-Gen (the root of Sophora subprostrata CHUN et T.CHEN) and their structures were established from their spectral data and comparison with the corresponding synthesized derivatives as 4', 7-dihydroxy-6, 8-bis(3-methyl-2-butenyl)flavanone (I), and 2-[(7'-hydroxy-2', 2'-dimethyl-2H-benzopyran)-6'-yl]-7-hydroxy-8-(3-methyl-2-butenyl)chroman-4-one (XI).
