| Abstract: | Volatile compounds of Jingzhi Baigan liquor were analyzed by liquid-liquid extraction and gas chromatographymass
spectrometry and identified by mass spectral library searching and comparison of retention indexes. Different
compounds were extracted by using different kinds of organic solvents with various polarities. The results showed that 30
compounds were identified in n-pentane extract compared to 29 compounds in ethyl ether extract and 35 compounds in
dichloromethane extract. In total, 65 compounds were extracted with three organic solvents including 9 alcohols, 19 esters,
11 acids, 14 alkanes, 3 aromatics, 3 furans, 3 aldehydes, 1ketones, 1 nitrogenous compound and 1 sulfocompound. |
