Erysubins C-F, four isoflavonoids from Erythrina suberosa var. glabrescences.
Four isoflavonoids, erysubins C-F, together with ten known compounds were isolated from the roots of Erythrina suberosa var. glabrescences, and their structures were elucidated on the basis of spectroscopic evidence. Erysubin C is an unusual pterocarpan derivative with a formyl group.
