竹醋液烟熏气化学成分的研究

采用固相微萃取(SPME)吸附采集竹醋液烟熏气的成分,用气相色谱—质谱联用分析鉴定,并用GC/MS总离子流色谱峰的峰面积进行归一化定量分析竹醋液烟熏气成分,鉴定出愈创木酚11.36%、苯酚10.6%、4-乙基苯酚8.23%、2-甲氧基-4-甲基苯酚7.08%、4-乙基-2-甲氧基苯酚6.6%、2-乙基苯酚5.65%、糠醛5.51%、5-甲基糖醛1.47%、乙酸1.42%、3-甲基-1-戊烯-3-醇1.42%、2,3-二甲基甲苯1.35%、2-糠酸甲酯1.35%、苯甲酸甲酯1.11%、2-甲基-2-环戊烯-1-酮1.44%、2,3-二甲基-2-环戊烯-1-酮1.31%、2-环戊烯-1-酮1.02%等74种化合物。竹醋液烟熏气的所有成分是竹醋液化学成分的特征性组成部分。

A Study on Chemical Component of Smoke Gas from Bamboo Vinegar

Chemical component of smoke gas of bamboo vinegar were investigated by gas chromatography-mass spectrometry.The volatiles were sampled by solid phase microextraction(SPME) and chemical components were separated and identified by GC-MS.Guaiacol(11.36%),phenol(10.6%),phenol,4-ethyl(8.23%),phenol,4methyl-2-methoxy(7.08%),phenol,4-ethyl-2-methoxy(6.6%),phenol,2-ethyl-(5.65%),furfural(5.51%),5-methyl(1.47%),acetic acid(1.42%),3-methyl1-penten-3-ol(1.42%),phenol,2,3-dimethyl(1.35%),Methyl 2-furoate(1.35%),benzoic acid,methy-ester(1.11%),2-methyl-2-cyclopenten-1-one(1.44%),2,3-dimethyl-2-cyclopenten-1-one(1.31%),2-cyclopenten-1-one(1.02%)were released from smoke gas of bamboo vinegar,and a total of 74 volatile compounds were identified in this study.
