Chromatographic investigation of a methanolic extract of white lupin roots has revealed the presence of six new dihydrofuranoisoflavones (lupinisoflavones A-F).Three monoprenylated (3,3-dimethylallyl-substituted) isoflavones (wighteone, luteone and licoisoflavone A), two diprenylated isoflavones and two pyranoisoflavones (parvisoflavone B and licoisoflavone B) have also been isolated from the same source.In addition to genistein, leaf extracts of L. albus contain 3'-O-methylorobol which is presumed to be precursor of lupisoflavone .Probable biogenetic relationships between the prenylated, and dihydrofurano- and pyrano-substituted isoflavones in roots and leaves of L. albus are briefly discussed.Key Word Index -- Lupinus albus; Leguminosae; dihydrofuranoisoflavones; lupinisoflavones A-F; pyranoisoflavones; prenylated isoflavones; 3'-O-methylorobol: fungitoxins.
