| Abstract: | The wood of Machaerium vestitum contains the previously described O-acetyloleanolic aldehyde, formononetin, (+)-medicarpin, and (?)-mucronulatol, besides (+)-vestitol [(3S)-7,2′-dihydroxy-4-methoxyisoflavan] and (+)-vesticarpan [(6aS,11aS)-3,10-dihydroxy-9-methoxypterocarpan]. The constitutions of vestitol and vesticarpan were deduced by spectra and confirmed by syntheses. |
