Abstract: The volatile compounds of Gujinggong liquor were analyzed by liquid鄄liquid extraction coupled
with GC鄄MS and identified by comparison with authentic standards, NIST 11 library and retention index.
Different compounds were extracted by using different organic solvents with various polarities. Compared
with diethyl ether and dichloromethane, n鄄pentane showed better extraction effect for aromatic com鄄
pounds; alkanes and sulfur鄄containing compounds, and dichloromethane showed better extraction effect
for heterocyclic compounds. A total of 188 volatile compounds were determined in Gujinggong liquor,
including 74 esters, 26 alcohols, 25 aromatic compounds, 20 acids, 14 alkanes, 8 aldehydes and ke鄄
tones, 8 sulfur鄄containing compounds, 7 acetals,4 heterocyclic compounds, and 2 lactone compounds.
About 167 compounds of them were identified by pure standard.
Key words: liquid鄄liquid extraction; gas chromatography鄄mass spectrometry; Gujinggong liquor; volatile
