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

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.
