基　　金：广西教育厅科研项目"三种中国南海红树林内生真菌次级代谢产物研究"(项目编号:KY2015LX598)

摘　　要：研究南海红树林内生真菌Sk-4的代谢产物。方法:采用硅胶柱色谱法、凝胶色谱法(Sephadex LH-20)、TLC(薄层层析法)等进行分离纯化,并通过氢谱、碳谱、质谱等数据分析鉴定化合物的结构。结果:分离出四个化合物从红树内生真菌的菌体中。经波谱解析,分别为:(1)大黄素-9,10-蒽二酮;(2)Curvulari n;(3)5,5’-氧-二亚甲基-双(2-呋喃甲醛);(4)3,8-二羟基-6-甲基-9-氧-9H-氧杂蒽-1-羧酸酯。结论:四个化合物均首次从南海红树林内生真菌Sk-4中分离得到。Objective： To study the secondary metabolites of mangrove endophytic fungus No·Sk-4 from the south china sea. Method： The compounds were isolated by column chromatography and identified on the basis of physic-chemical constants and spectral analysis. Result：Four metabolites were obtained and elucidated as 1,3,8-trihydroxy-6-methyl-9,10-anthraquinone（1）, Curvularin（2）, 5,5’-oxy-dimethylene-bis（2-fur-aldehyde）（3）, 3,8-dihydroxy-6-methyl-9-oxo-9H-xanthene-1-carboxylate（4）.Conclusion： The four metabolites were obtained from endophytic fungus No·Sk-4 for the first time.
