Flavonoids from the pods of Millettia erythrocalyx.

From the pods of Millettia erythrocalyx, 2'-hydroxy-3,4-dimethoxy-[2'',3'':4',3']-furanochalcone, 2',3-dihydroxy-4-methoxy-4'-gamma,gamma-dimethylallyloxychalcone, (-)-(2S)-6,3',4'-trimethoxy-[2'',3'':7,8]-furanoflavanone, 3',4'-methylenedioxy-[2'',3'':7,8]-furanoflavonol and 6,3'-dimethoxy-[2'',3'':7,8]-furanoflavone were isolated, along with six other known flavonoids. Their structures were elucidated through analysis of their spectroscopic data.
