Abstract: Aim: To study the antitumor activities of the constituents of Cephalotaxus fortunei distributed in Guizhou province. Methods: The constituents were isolated by column chromatography and identified by physical and spectral analysis. Meanwhile, the anti-tumor activities of some compounds were evaluated by sulforhodamine B( SRB) and MTT assay. Results: Eleven compounds were isolated and identified as apigenin (Ⅰ), β-sitosterol (Ⅱ), acetylcephalotaxine (Ⅲ), chrysoeriol (Ⅳ), drupacine ( Ⅴ), 1-hentriacontanol ( Ⅵ), 7, 3', 4' -trihydroxyfla-vone (Ⅶ), sugiol ( Ⅷ), cephalotaxine (Ⅸ), wllsonine (Ⅹ), and hainanolide (Ⅺ), respectively. Biological screening results demonstrated that some of the tested compounds exhibited the antitumor activities in vitro. Conclusion: Compounds Ⅱ, Ⅵ-Ⅷ were isolated from this plant for the first time. Compound Ⅺ has a better inhibitory activity on cell line A549 and K562 .
