基于HS-SPME-GC-MS 法分析春生田头菇子实体不同部位挥发性成分

Analyses of Volatile Components in Different Parts of Agrocybe praecox by HS-SPME-GC-MS

摘要:

春生田头菇具有独特的香味风格。采用顶空固相微萃取法结合气相色谱-质谱联用技术，对春生田头菇子实体菌盖和菌柄的挥发性成分进行测定。从菌盖和菌柄分别鉴定出48种和47种化合物，其中16种为相同物质，占挥发性物质的20.25%。主要以烷类、酮类、酯类和酸类化合物为主，其中十甲基环五硅氧烷、2-甲基-3-庚酮、丙位壬内酯、3-羟基扁桃酸乙酯和苯乙酸为菌盖和菌柄共同含有且相对含量最高的化合物。对春生田头菇挥发性成分进行了系统研究，为进一步开发利用田头菇中活性物质提供支撑。

Abstract:

Agrocybe praecox has a unique flavor style. The volatile components in pileus and stipe of Agrocybe praecox were determined by head-space solid phase microextraction combined with gas chromatography-mass spectrometry(HS-SPME-GC-MS). There were 48 and 47 volatile compounds identified from the pileus and stipe of Agrocybe praecox, respectively, 16 of which were the same components, accounting for 20.25% of the volatile components. These compounds were mainly alkanes, ketones, esters and acids, of which decamethylcyclopentasiloxane, 2-methyl-3-heptanone, dihydro-5-pentyl-2(3H)-furanone, 3-hydroxymandelic acid and benzeneacetic acid were the common components of pileus and stipe of Agrocybe praecox with relative high content. The volatile components in the Agrocybe praecox were systematically studied to provide theoretical support for further develop and utilization of the compoundsin Agrocybe praecox.
