FLAVONOIDS AND ISOFLAVONOIDS FROM TEPHROSIA FULVINERVIS AND TEPHROSIA PENTAPHYLLA

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 α-toxicarol) and the flavanone obovatin were obtained.A similar analysis of the roots of T. fulvinervis yielded only known rotenoids (α-toxicarol, deguelin, munduserone, cis-12a-hydroxymunduserone) and the common pterocarpan (-)-maackiain. Key Word Index Tephrosia fulvinervis; T. pentaphylla; Papilionoideae; Leguminosae; isoflavone derivatives; rotenoids.
DEHYDRO-6-HYDROXYROTENOID AND LUPENONE FROM TEPHROSIA VILLOSA
Prashant, A.,Krupadanam, G. L. David
, p. 484 - 486 (1993)
A new dehydro-6-hydroxyrotenoid, 12a-dehydro-6-hydroxysumatrol and lupenone were isolated from whole plants of Tephrosia villosa.Their structures were elucidated from chemical and spectroscopic evidence.The new rotenoid structure was confirmed by its partial synthesis from 6a,12a-dehydrosumatrol.Key Word Index - Tephrosia villosa; Leguminosae; dehydro-6-hydroxyrotenoid; lupenone.
