Isoflavonoids from the roots of Erythrina poeppigiana.
Five isoflavonoids, 7,4'-dihydroxy-2'-methoxy-8-(gamma,gamma-dimethylallyl)isoflav-3-ene, 4'-hydroxy-2'-methoxy-6",6"-dimethylpyran[2",3":7,8]isoflav-3-ene, 5,7,4'-trihydroxy-2'-methoxy-5'-(gamma,gamma-dimethylallyl)isoflavanone, 5,4'-dihydroxy-7,2'-dimethoxy-5'-(gamma,gamma-dimethylallyl)isoflavanone and 3,9-dihydroxy-4-(gamma,gamma-dimethylallyl)pterocarpene as well as six known compounds were isolated from the roots of Erythrina poeppigiana. Their structures were established on the basis of spectroscopic evidence.
