Further isoflavonoids from white lupin roots

Abstract

Further investigation of the isoflavonoids in white lupin roots has revealed a new coumaronochromone with a 2-hydroxy-3-methyl-3-butenyl side chain (lupinalbin G), three new pyrano-isoflavones (lupinisoflavones K and L, and allolicoisoflavone B) and two new dihydrofurano-isoflavones each with a 2, 3-dihydroxy-3-methylbutyl substituent (lupinisoflavones M and N). The biogenetic pathways for these and other lupin isoflavones are briefly discussed. © 1990, Walter de Gruyter. All rights reserved.
