摘    要:建立了气相色谱串联质谱(GC-MS)准确、快速测定香精香料中仲丁醇、富马酸二甲酯、咪唑和芝麻酚的分析方法.样品经甲醇超声提取15min后,通过Agilent DB-WAX(0.25mm×30m×0.25μm)色谱柱分离,质谱进行定性,外标法对于4种目标物质进行定量分析.实验结果表明,在0.5-20mg/L的范围内,4种物质具有较好的线性,各待测物质的线性相关系数均大于0.9990,检出限为0.02-0.12mg/L,在1,5mg/L和10mg/L 3个加标水平条件下,4种禁限用物质的平均回收率为88.0%-113.1%,相对标准偏差为0.32%-6.53%.该方法前处理简单,灵敏度高,线性相关性好,重复性佳,可以满足香精香料中4种物质的同时检测.

关 键 词:气相色谱串联质谱  仲丁醇  富马酸二甲酯  咪唑  芝麻酚  分离

Abstract:A gas chromatography coupled with mass spectrometry as detector (GC-MS) was established for the separation and determination of 4 substances (s-butanol, dimethyl fumarate, imidazole,sesamol) in flavor and fragrant samples. After extracted by HPLC methanol, the target compounds were separated on an Agilent DB-WAX capillary column (0.25mm×30m×0.25μm). Selected ion monitoring (SIM) mode of GC-MS was used in quantitation. It's exhibited that there was a good linear relationship (〉0. 9990) ranged from 0. 5 to 25mg/L and the limits of detection was in range of 0. 02--0.12mg/L. The average recoveries at three levels were in the range of 88.0%-- 113.1% with the relative standard deviations (RSD)ranged from 0. 32% to 6. 53%. This simple method can be used to determine 4 substances in flavor and fragrant samples simultaneously.
Keywords:Gas Chromatography-Mass Spectrometry(GC-MS)  s-Butanol~Dimethyl Fumarate  Imidazole  Sesamol  Separation
