Seven alkaloids were isolated from Cephalotaxus sinensis (Rehd. et Wils.) Li and were identified by elements analysis, melting point and spectral data. Six of them are known alkaloids: cephalotaxine (Ⅰ), Ⅱ-hydroxyeephalotaxine (Ⅱ), drupaeine (Ⅲ), demethylcephalotaxinone (Ⅳ), c-3epi-witsonine (Ⅴ) and wilsonine (Ⅵ). Cephalo- taxine is the major alkaloid of this plant. (Ⅰ–Ⅳ) are alkaloid of Cephalotaxus type and another two (Ⅴ–Ⅵ) are alkaloid of homoerythrina type. (Ⅶ) seems to be a new alkaloid. Its strueture will be studied further.
