【 摘 要 】

Four flavonoids, 3,7,4'-trihydroxyflavanone (garbanzol), 7,4'-dihydroxyflavone, 7,4'-dihydroxy-3'-methoxyflavone (geraldone) and 3,4,7,4'-tetrahydroxyflavane (Rel-2R,3S,4S-leucoguibourtinidine, guibourtacacidine) were isolated from the wood of Schizolobium parahyba (Leg., Caesalpinoideae) together with lignan balonofonine, sitosterol, and stigmasterol. The structures were established by IR, NMR and mass spectral data analysis and comparison with literature values.
