摘要: 对中国南海500 m深海水来源真菌Exophiala sp.SCSIO 05791进行了次级代谢产物研究;综合运用硅胶柱层析、Sephadex LH-20凝胶柱层析、中压反相柱层析以及半制备高效液相等色谱学方法对其大米发酵产物进行分离纯化,从中分离到8个单体化合物,利用核磁共振、质谱等波谱学手段并结合其理化性质及文献数据鉴定了其化学结构:stephacidin A(1)、吲哚-3-乙酸(2)、环(D)-脯氨酸-(D)-苯丙氨酸(3)、反式阿魏酸(4)、顺式阿魏酸(5)、2-(乙酰氨基)-苯酚(6)、氨基苯甲酸(7)、4-羟基苯酞(8)。化合物1~8均为首次从该属中分离得到。

Abstract: The secondary metabolites of Exophiala sp.SCSIO 05791,a fungus isolated from South China Sea 500 m depth water,were investigated.Eight compounds were obtained from the rice static fermentation products,which were purified by comprehensive chromatography methods of silica gel column,Sephadex LH-20, Ostade-cylsilane (ODS),and semi-preparative HPLC and their structures were elucidated by means of physical and chemical properties,spectroscopic analysis,and comparison with the reported literatures,which were stephacidin A(1),indole-3-acetic acid (2),cyclo(D)-Pro-(D)-Phe(3), trans-ferulic acid(4), cis-ferulic acid (5), 2-(acetylamino)-phenol (6),anthranilic acid(7) and 4-hydroxyphthalide (8).Compounds 1-8 were all obtained from genus Exophiala for the first time.
