| 中文摘要:为了评价细支卷烟中树苔香味物质从烟丝向烟气的迁移情况，建立了气相色谱-质谱联用(GC-MS)选择离子法测定卷烟烟丝和烟气中苔黑酚单甲醚、苔黑酚、β 苔黑酚羧酸甲酯、苔黑酚羧酸乙酯和十六酸乙酯的检测方法。考察了萃取溶剂、萃取时间和基质效应对分析结果的影响，最终确定以乙酸乙酯作为萃取溶剂，并使用基质匹配标准溶液进行外标法定量。5个目标物在0.02~20 mg/L的质量浓度范围内线性关系良好(r2＞0.996)。在烟丝中，检出限(S/N=3)和定量下限(S/N=10)分别为0.79~3.0 ng/mL和2.6~10.0 ng/mL，平均加标回收率为90.5%~103%，相对标准偏差(RSDs，n=6)为23%~12%；在烟气中，检出限(S/N=3)和定量下限(S/N=10)分别为0.60~2.9 ng/mL和2.0~9.6 ng/mL，平均加标回收率为85.6%~104%，相对标准偏差(RSD，n=6)为1.6%~9.3%。结果表明，该方法简便、灵敏、线性关系好，能满足卷烟烟丝和烟气中5种目标物质的测定要求。运用该方法对烟丝和烟气中5种树苔成分的含量进行测定，并评价了其由细支卷烟的烟丝向烟气的迁移率。 |

| Determination of Five Treemoss Flavoring Compounds in Slim Cigarette by Gas Chromatography-Mass Spectrometry |

| Abstract:To evaluate the migration of treemoss flavoring compounds in slim cigarettes from cut tobaaco to tobacco smoke,a gas chromatography–mass spectrometry(GC-MS) in selected ion monitoring mode was developed for the determination of orcinol monomethyl,orcinol,methyl atratate,ethyl hexadecanoate and ethyl orsellinate in cut tobacco and tobacco smoke.The influences of solvent,extraction time and matrix effect were investigated.The tobacco sample was extracted with ethyl acetate,and quantified externally with matrix matched standard solution.Under the optimized conditions,there were good linear relationships for 5 selected analytes in the range of 0.02-2.0 mg/L with their correlation coefficients(r2) larger than 0.996For cut tobacco,the limits of detection(LODs) and limits of quantitation(LOQs) were in the ranges of 0.79-30 ng/mL and 2.6-10.0 ng/mL,respectively,with spiked recoveries of 90.5%-103% and relative standard deviations(RSDs,n=6) of 2.3%-12%.For tobacco smoke,LODs and LOQs were in the ranges of 0.60-2.9 ng/mL and 2.0-9.6 ng/mL,respectively,with average spiked recoveries of 856%-104% and RSDs(n=6) of 1.6%-9.3%.The proposed method was applied in the determination of 5 analytes in cut tobacco and tobacco smoke followed by the evaluation of the migration of treemoss components from cut tobacco to tobacco smoke.The results showed that the method was handy,sensitive and reliable,and could satisfy the requirements for the determination of the 5 analytes both in cut tobacco and tobacco smoke. |
