摘　　要：目的研究中国南海侧扁软柳珊瑚（Subergoria suberosa）中的化学成分。方法应用硅胶柱色谱、Sephadex LH-20凝胶柱色谱、开放ODS柱色谱、半制备反相高效液相色谱法（RP-HPLC）等多种色谱手段,对侧扁软柳珊瑚的乙醚提取物进行分离纯化,运用现代波谱技术结合文献报道的数据对分离得到的化合物进行结构鉴定,还检测了所得10个开环甾醇类化合物对人肺腺癌细胞（A549）和人骨肉瘤细胞（MG63）的体外抗肿瘤活性以及对白假丝酵母菌（Candida alicans）和烟曲霉菌（Aspergillus fumigatus）的体外抗真菌活性。结果和结论从中国南海侧扁软柳珊瑚中共分离到10个开环甾醇类化合物,化合物2、7为首次从该属珊瑚中分离得到。在体外抗肿瘤细胞生长抑制活性测试中,化合物3~6及9对人肺腺癌细胞（A549）和人骨肉瘤细胞（MG63）显示不同程度的抑制活性,其IC50值分别为6.31、30.42、8.33、9.57、3.30μg/mL和30.83、21.32、9.19、28.01、8.62μg/mL;在抗真菌活性测试中,10个化合物对白假丝酵母菌（Candida albicans）和烟曲霉菌（Aspergillus fumigatus）均未表现出抑制作用。Objective To investigative the chemical components of Subergorgia suberosa collected from the South China Sea.Methods The Et2 O extract of S.Suberosa was purified by repeated column chromatography on silica gel,Sephadex LH-20,ODS,and semi-preparative RP-HPLC.The structures of obtained compounds were determined by spectroscopic analysis and comparison with previously reported data.The anti-tumor activity of 10 obtained 9,11-secosterols were tested with human lung adenocarcinoma A549 cell line and human osteo-sarcoma MG63 cell line;the antifungal activities of them were tested with Candida albicans and Aspergillus fumigatus in vitro.Results and Conclusion Ten 9,11-secosterols were isolated from Subergorgia suberosa collected from the South China Sea.Compounds 2 and 7 have been obtained for the first time from the genus of gorgonian Subergorgia.In vitro anti-tumor experiment showed that compounds 3-6 and 9 had different degrees of tumor inhibitory effects against cell lines A549 and MG63,with the IC50 values being 6.31,30.42,8.33,9.57 and 3.30μg/mL for A549 cell line and 30.83,21.32,9.19,28.01 and 8.62μg/mL for MG63 cell line,respectively.The ten steroids showed no anti-fungi activity against Candida albicans or Aspergillus fumigatus in vitro.
