花脸香蘑液体发酵次生代谢产物中挥发性物质的化学成分研究

摘要

Volatile components were analyzed in liquid fermentation of Lepista sordida(Fr)Sing by GC-MS and identified by NIST147 standard mass spectrum databank and personal analysis. Nineteen peaks were separated by GC whose of sixteen were identified from liquid fermentation,sixteen peaks were separated by GC whose of fourteen were identified from CPDA culture medium. Main constituents of fermentation secondary metabolites were found to be 1-Decanol,1,2-Benzendicarboxylic acid,2,6-Dichlorophenylisothiocyanate,Benzenemethanol,1-H-3α,7-Methanazulen-5ol,2-Chloro-4,5-dimethoxybenzaldehyde,5-Chloro-2-methoxybenzoic acid,Geranic acid,Pyrrolo[1,2-α]pyrazine-1,4-dione,Cyclo-(1-leucyl-1-phenylalanyl).%采用GC-MS联用技术,结合质谱信息经计算机检索NIST147标准质谱图库与人工解析,分析了花脸香蘑Lepista sordida(Fr) Sing菌株发酵液CH2Cl2提取物的挥发性成分,发酵液中气相色谱共分离了19个峰,经解析确定了16个成分,在培养基(对照组)中CH2Cl2提取物气相色谱共分离了16个峰,经解析确定了14个成分,主要次生代谢产物为1-Decanol,1,2-Benzendicarboxylic acid,2,6-Dichlorophenylisothiocyanate,Benzenemethanol,1-H-3α,7-Methanazulen-5ol,2-Chloro-4,5-dimethoxybenzaldehyde,5-Chloro-2-methoxybenzoic acid,Geranic acid,Pyrrolo[1,2-α]pyrazine-1,4-dione,Cyclo-(1-leucyl-1-phenylalanyl).
