摘要: 以药用植物结香(Edgeworthia chrysantha)来源的一株内生真菌烟曲霉D(Aspergillus fumigatus D)为研究对象,通过玉米固体发酵、乙酸乙酯提取、低温真空浓缩获得粗浸膏,采用现代色谱技术分离纯化到7个次级代谢产物,利用NMR、MS等波谱技术结合其理化性质及文献数据鉴定了它们的化学结构,分别为stemphyperylenol(1)、altertoxin I(2)、alterperylenol(3)、maculosine(4)、brevianamide F(5)、cyclo(L-Pro-L-Leu)(6)、2-(1H-indole-3-yl) ethyl acetate(7),其中化合物1~3为首次从烟曲霉中分离得到。体外抗菌研究表明,化合物1~7对三种人源病原菌(Escherichia coliStaphylococcus aureusCandida albicans)均无显著的抑制活性(MIC>100 μM)。

Abstract:

The structure and bioactivity diversities of Aspergillus fumigatus D,an endophytic fungus derived from the fresh leaves of Edgeworthia chrysantha,have been researched.Seven secondary metabolites were purified from the corn culture medium by semi-preparative HPLC column.By a combination of spectroscopic methods including 1D NMR and MS as well as comparison with the literatures,chemical structures of these compounds were respectively identified as stemphyperylenol (1),altertoxin I (2),alterperylenol (3),maculosine (4),brevianamide F (5),cyclo (L-Pro-L-Leu) (6),2-(1H-indole-3-yl) ethyl acetate (7),of which compounds 1-3 were firstly isolated from the species A. fumigatus.In vitro antibacterial studies showed that compounds 1-7 had no significant inhibitory activity against three human pathogenic bacteria (Escherichia coli,Staphylococcus aureus,Candida albicans) (MIC> 100 μM).

Key words: Edgeworthia chrysantha, endophytic fungus, Aspergillus fumigatus, perylenequinone
