Two new isoflavonoids 7,8,4′-trimethoxyisoflavone and 7,8,4′-trimethoxyisoflavanone and calycosin (7,3′-hydroxy-4′-methoxyisoflavone) were isolated from the wood of the leguminous tree Bowdichia virgilioides by usual chromatographic procedures. Besides these compounds the pterocarpane (-)-maackianin, isoliquiritigenin (4,2′,4′-trihydroxychalcone), and the hydrobenzylfurane derivative bowdenol were also obtained. The structures of these new compounds were determinated by MS and 1D and 2D NMR spectral analysis. [ABSTRACT FROM AUTHOR] |
