Abstract

Four novel complex isoflavones ulexones A, B, C and D, 5,7-dihydroxy-8-(3,3-dimethylallyl)-[6'',6''-dimethylpyrano (2'',3'':4',3')]-isoflavone, 5-hydroxy-[6'',6''-dimethylpyrano (2'',3'':4',3)] [6,6-dimethylpyrano (2,3:7,8)]-isoflavone, 5-hydroxy-[6'',6''-dimethylpyrano (2'',3'':4',3')] [1,2-dihydro-2-(1-hydroxy-1-methylethyl)-furano (4,5:7,8)]isoflavone, 5-hydroxy-[6'',6''-dimethylpyrano (2'',3'':4',3')] [6-methyl-6-(hydroxymethyl)-pyrano (2,3:7,8)]-isoflavone, have been isolated from the root bark of Ulex europaeus. Genistein and 5-O- methylgenistein were also present. Structures were established fromthe NMR spectra
