摘要：

Objective: To study the antitumor activities of the liposoluble components from caulis Marsdenia tenocissimae and analyze its chemical constituents.Method: The supercritical fluid extraction was used to extract the liposoluble components from caulis M.tenocissimae.MTT test was applied to study the anticancer effects of liposoluble components on growth inhibition in human liver cancer line HepG-2 cells,and the chemical constituents were analyzed by gas chromatography/mass spectrometry(GC-MS).Result: The liposoluble components of caulis M.tenocissimae have obvious growth inhibitory action to HepG-2 cells.Twenty-four compounds were identified and their relative contents were determined.Conclusion: The liposoluble components from caulis M.tenocissimae have antitumor activities,and its pharmacological activity is related to its chemical constituents.
