Abstract:

In continuation of our chemical investigation on some medicinal plants of the genus Tephrosia, reinvestigation of the methylenechloride/methanol (1:1) extract of the aerial parts of Tephrosia purpurea yielded an aromatic ester 1, a sesquiterpene 2 and prenylated flavonoid 3. The structures of the compounds were established by comprehensive NMR studies, including DEPT, COSY, NOE, HMQC, HMBC, EIMS and CIMS.

Keywords:Aromatic ester, Prenylated flavonoid, Sesquiterpene, Tephrosia purpurea
