目的：研究绿升麻中对肿瘤细胞有细胞毒活性的化学成分。方法：以硅胶柱、凝胶等多种柱色谱分离，制备高效液相色谱纯化，以各种波谱鉴定化合物结构。结果：分离得到1个环阿屯烷型三萜类化合物，鉴定其结构为(23R)-16β,23∶23α,26∶24α∶25-triepoxy-9,19-cyclolanost-7-en-3-O-β-D-xylopyranoside。结论：化合物1是新化合物，命名为(23R)-26-deoxycimicifugoside。化合物1对宫颈癌细胞(Hela)和小鼠成纤维细胞(L929)具有一定的细胞毒作用，IC₅₀分别为72.24，55.97 mg·L^-1。

A new cycloartane triterpene saponin from rhizome of Actaea asiatica

OBJECTIVE: To isolate and elucidate the chemical constituents with the cytotoxicity activity from the rhizome of Actaea asiatica. METHOD: The chemical constituents were isolated by repeated column chromatography (Toyopearl HW40C and preparative HPLC) and the structure of compound 1 was elucidated by spectral data analysis. RESULT: A cycloartane triterpene saponin com- pound was isolated and identified to be (23R)-16beta, 23: 23alpha, 26: 24alpha: 25-triepoxy-9, 19-cyclolanost-7-en-3beta-O-beta-D-xylopyranoside. CONCLUSION: Compound 1 was a new compound and named (23R)-26-deoxycimicifugoside. The IC50 values of compound 1 for cell growth inhibition of Hela and L929 cell lines were 72.24 and 55.97 mg x L(-1), respectively.
