摘要:

采用不同的溶剂,通过液液萃取法结合气-质联机对景芝白干酒中的香气成分进行分析,并通过NIST 11 谱库 检索和保留指数进行了鉴定。结果表明,不同种类和极性的有机溶剂,其萃取出来的成分也不相同。采用正戊烷作为 萃取剂,共发现30 种物质,采用乙醚作为萃取剂,共发现29 种物质,采用二氯甲烷作为萃取剂,共发现35 种物质。 3 种溶剂一共萃取出65 种物质,其中醇类化合物9 种、酯类化合物19 种、酸类化合物11 种、烃类化合物14 种、芳香 族化合物3 种、呋喃类化合物3 种、醛类化合物3 种、酮类化合物1 种、含氮化合物1 种、含硫化合物1 种。

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.

Key words: liquid-liquid extraction, organic solvent, Jingzhi Baigan liquor, flavor compounds, gas chromatography-mass spectrometry (GC-MS)
