目的研究中药土木香的化学成分。

OBJECTIVE: Three sesquiterpene lactones 1-O-acetylbritannilactone, isoalantolactone and britannilactone were isolated from the roots of Inula helenium and the flowers of Inula japonica. The antitumor activities of the three sesquiterpenoids in the cell lines of HeLa, HEC-1, SHIN3, HOC-21 and HAC-2 were measured, and the relationship between structure and activity and the possible mechanisms were explored.
