In continuation of our chemical investigation on some medicinal plants of the genus Tephrosia, re-investigation of the methylenechloride/methanol (1:1) extract of the air-dried aerial part of Tephrosia apollinea afforded a new prenylated flavonoid 1,in addition to an aromatic ester, a sesquiterpene, a lignan and several known prenylated flavonoids.The structures were established by (1H NMR,13C NMR, DEPT,1H-1H COSY, HMQC, HMBC, NOESY and HRMS).Relative configurations of 9 and 10 wereconfirmed by X-ray analysis.
