摘要
以一株怀山药内生毛壳菌Chaetomium sp.L-45为研究对象,对其次生代谢产物进行分离和结构鉴定.对毛壳菌进行大米发酵,通过硅胶柱色谱、Sephadex LH-20、半制备高效液相色谱等分离技术分离发酵物的乙酸乙酯提取物,利用NMR、HR-ESI-MS等波谱解析技术进行化合物的结构鉴定.从目标菌株的乙酸乙酯提取物中分离得到4个化合物,分别鉴定为3,4-二甲氧基-5-羟基-6-丙基-苯甲酸(1)、5-异戊烯基-吲哚-3-羧酸(2)、lecanorin(3)和麦角甾醇(4),其中,化合物1为新化合物,化合物2和3系首次从毛壳菌属真菌中分离得到.
Abstract
In this study,the secondary metabolites of an endophytic Chaetomium sp.L-45 from Dioscorea opposita were isola-ted and identified.The ethyl acetate extract of the rice fermentation of the fungus were separated by silica gel column chroma-tography,Sephadex LH-20,semi-preparative High-performance liquid chromatography,etc.,and the chemical structures of the compounds were identified by NMR and HR-ESI-MS analysis.As a result,four compounds were isolated and identified as 3,4-dimethoxy-5-hydroxy-6-propyl-benzoic acid(1),5-isoprenylindole-3-carboxylic acid(2),lecanorin(3),and ergosterol(4).Among them,compound 1 is a new compound,compounds 2 and 3 were isolated from genus Chaetomium for the first time.
