Flavonoids and isoflavonoids from tephrosia fulvinervis and tephrosia pentaphylla



Flavonoids and isoflavonoids from tephrosia fulvinervis and tephrosia pentaphylla



Phytochemistry 28(11): 3207-3210



From the roots, leaves and pods of Tephrosia pentaphylla three new 6-oxygenated rotenoids (dihydrostemonal, 9-demethyldihydrostemonal and 6-acetoxydihydrostemonal) were isolated and characterized. In addition six known rotenoids (villosin, sumatrol, rotenone, cis-12a-hydroxyrotenone, 6-hydroxyrotenone and .alpha.-toxicarol) and the flavanone obovatin were obtained. A similar analysis of the roots of T. fulvinervis yielded only known rotenoids (.alpha.-toxicarol, deguelin, munduserone, cis-12a-hydroxymunduserone) and the common pterocarpan (-)-maackiain.
