摘要: 利用柱色谱技术,分离纯化来源于柳珊瑚的两株海洋真菌(Aspergillus sclertoiorumPenicillium citrinum)共培养发酵代谢产物,通过NMR 等波谱学数据进行结构鉴定,并利用HPLC分析A.sclertoiorum分别共培养和纯培养时主要次生代谢产物产量的差异。从共培养的乙酸乙酯提取物中分离鉴定了4个化合物,分别为青霉酸(1),5,6-dihydropenicillic acid(2),6-dihydro-6-hydroxy penicillic acid(3),2-hydroxy-3,6-dimethylbenzoic acid(4),其中化合物4为首次从海洋来源真菌中得到,并且共培养不同程度地提高了化合物1~4的产量。

Abstract: Four compounds were yielded by a microbial co-culture of the gorgonian-associated fungus Aspergillus sclertoiorum and Penicillium citrinum, including penicillic acid(1),5,6-dihydropenicillic acid(2),6-dihydro-6-hydroxy penicillic acid(3)and 2-hydroxy-3,6-dimethylbenzoic acid(4).The structures of them were elucidated by the analysis of NMR data and comparison with literatures.HPLC was applied for the analysis of the production of 1-4 and they were enhanced in different level in the co-culture compared with A.sclertoiorum cultured individually.Compound 4 was obtained from marine fungus for the first time.

Key words: Gorgonian-associated fungus, Aspergillus sclertoiorum, Penicillium citrinum, co-culture, secondary metabolites
