Abstract:
Two new sesquiterpenoid esters (1 and 2) were isolated from the extract of Blumea balsamifera, a tropical Compositae plant. Compound 2 proved to be weakly cytotoxic when tested against Jurkat human T-cell leukemia cells. Nine known flavonoids, of which two showed plasmin-inhibitory activity, were also isolated.
