Article abstract of DOI:10.1016/0031-9422(90)85212-X

Immature seeds of M. ferruginea subsp. ferruginea and subsp. darassana yielded three rotenoids (rotenone, tephrosin and 12a-hydroxyrotenone), four pyrano-isoflavones (ferrugone, durmillone, calopogonium isoflavone-A and barbigerone) and three novel C-prenylated isoflavones named preferrugone, predurmillone and prebarbigerone.The root bark of the latter subspecies also afforded the novel C-prenylated isoflavone pre-5-methoxydurmillone.
