Flavonoids from the pods of Millettia erythrocalyx

2′-Hydroxy-3,4-dimethoxy-[2″,3″:4′,3′]-furanochalcone, 2′,3-dihydroxy-4-methoxy-4′-γ,γ-dimethylallyloxychalcone, (−)-(2 S)-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 from the pods of Millettia erythrocalyx, along with six other known flavonoids. From the pods of Millettia erythrocalyx, 2′-hydroxy-3,4-dimethoxy-[2″,3″:4′,3′]-furanochalcone, 2′,3-dihydroxy-4-methoxy-4′-γ,γ-dimethylallyloxychalcone, (−)-(2 S)-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.
