摘　　要：以添加美拉德反应产物(MRPs)前后的卷烟为研究对象,通过剑桥滤片捕集卷烟主流烟气粒相物,利用溶剂萃取的方法提取香味成分。采用气相色谱-质谱法同时测定卷烟主流烟气中15种酚类成分的含量。在气相色谱分离中采用HP-5MS色谱柱,在质谱分析中采用选择离子监测模式。以乙酸苯乙酯为内标。方法的检出限(3s)为0.14~2.12mg·L-1,测定下限(10s)为0.46~7.07mg·L-1。方法用于卷烟样品的分析,加标回收率为86.4%~105%,测定总量的相对标准偏差(n=5)为1.4%~7.2%。随着MRPs添加量的增加,主流烟气中大部分酚类成分含量及总量均呈现降低趋势,一定程度上可以提高卷烟安全性。Cigarettes before and after adding Maillard reaction products(MRPs)were used as research objects,and mainstream smoke particulate matter was captured by Cambridge filter.The flavor components were extracted by solvent extraction method.GC-MS was applied to the simultaneous determination of 15 phenolic components in cigarette mainstream smoke.The HP-5 MS chromatographic column was used for GC separation and the selected ion monitoring mode was adopted in MS determination.Phenethyl acetate was used as internal standard.Detection limits(3 s)of the method ranged from 0.14 to 2.12 mg·L-1 and lower limits of determination(10 s)ranged from 0.46 to 7.07 mg·L-1.The proposed method was applied to the analysis of the sample of cigarette,giving values of recovery found by standard addition method and RSDs(n=5)of determined total amounts in the ranges of 86.4%-105% and 1.4%-7.2% respectively.With the increase of the additive amount of MRPs,the content and total amount of most phenolic components in mainstream smoke showed a decreasing trend,to a certain extent,which improves the safety of cigarettes.
