Article abstract of DOI:10.1016/0031-9422(80)85140-5

Extraction of Millettia pachycarpa Benth. gave 5,7,4'-trihydroxy-6,8-diprenylisoflavone (1a), 5,7,4'-trihydroxy-6,3'-diprenylisoflavone (2a), 5,7,3',4'-tetrahydroxy-6,8-diprenylisoflavone (3a) and (2R,3R)-5,4'-dihydroxy-8-prenyl-6'',6''-dimethylpyrano<2'',3'':7,6>-dihydroflavonol (4a) whose structures were established by chemical transformations and spectroscopic means.Pectolinarigenin and salvigenin were isolated from Buddleia macrostachya Benth. - Key Word Index: Millettia pachycarpa; Leguminosae; Lotodoideae; prenylated isoflavones; prenylated dihydroflavonols; Buddleia macrostachya; Buddleiaceae; pectolinarigenin; salvigenin.
