摘要: 采用硅胶柱层析、Sephadex LH-20凝胶柱层析、中压反相柱层析以及半制备高效液相色谱等方法对韩国南部海岸来源的越前水母共附生真菌A. fumigatus的大米发酵产物进行分离纯化,并利用核磁共振、质谱等波谱学方法结合其理化性质及文献数据鉴定了7个单体化合物的结构:sinulariapeptide C(1)、simplicilliumtide A(2)、simplicilliumtide B(3)、sinulariapeptide D(4)、4-羟基-17R-甲基降甾醇(5)、3-羟基苯乙酸甲酯(6)、邻苯二甲酸二丁酯(7)。化合物1~7均为首次从越前水母来源的菌属中分离得到。

Abstract: The secondary metabolites of A. fumigatus sp.,a fungus isolated from the jellyfish Nemopilema nomurai collected off the southern coast of Korea,were studied.Seven compounds were obtained from the rice static fermentation products,which were purified by the methods of silica gel,Sephadex LH-20 gel,reversed-phase and semi-preparative HPLC column chromatography.The structures of these compounds were identified as sinulariapeptide C(1),simplicilliumtide A(2),simplicilliumtide B(3),sinulariapeptide D(4),4-hydroxy-17R-methylincisterol(5),methyl 3-hydroxyphenyl acetate(6) and dibutyl phthalate(7) by physical and chemical properties,spectroscopic analysis,and comparison with the reported literatures.Compounds 1-7 were isolated from the jellyfish-derived fungus A. fumigatus for the first time.

Key words: Nemopilema nomurai, jellyfish-derived fungus, Aspergillus fumigatus, secondary metabolites
