The volatile constituents in the pit muds from different parts of Luzhou Laojiao cellar with 50 years were detected and analyzed.Gas chromatograph-mass spectrum(GC-MS) coupled with head-space solid phase microextraction(HS-SPME) were employed.65 volatile compounds were identified,mainly were esters,alcohols,acids,aldehydes,ketones and phenols.There were only small differences in the compounds of alcohol,aldehyde,ketone and phenol between the cellar wall mud and the bottom cellar mud,while significant discrepancies in acids and easters.Hexanoic acid,butyl hexanoate and hexyl hexanoate were the characteristic components in the cellar wall mud,while methyl caproate in the bottom cellar mud.
