目的]建立静态顶空-气相色谱质谱应用于卷烟烟丝中关拉德反应的风味物质快速分析的方法。方法]将供试样品经120℃、30min静态顶空后，采用DB-624柱，气相色谱-质谱全扫描检测。结果]试验共检测出卷烟烟丝中关拉德反应风味物质60种，其中包含醇类、醛酮类、酸类、酯类、杂环类和其他类，采用峰面积归一法确定了各成分的相对含量。结论]该方法具有简单快速、风味物质损失少等特点，应用于实际样品检测取得了良好效果，并适用于美拉德反应机理和应用研究。

Rapid Detection of Flavors from Maillard Reaction in Cut Tobacco of Cigarette by Static Headspace Gas Chronmatograph-Mass Spec-trometry

Objective ] In order to rapidly determine flavors from Maillard reaction in cut tobacco of cigarette, a static headspace gas chromatog-raphy-mass spectrometry （SHS-GC/MS） was developed. Method] Samples were treated at 120 ℃ for 30 min,and then the evolved products were separated on a DB-624 column. Result] Total of 60 compounds were identified by GC-MS,including alcohols, aldehyde and ketones, acids, esters,herocyclics and other compounds. The relative content of the components were determined with area normalization method. Conclusion ] The method is simple,rapid, sensitive, and is suitable for the analysis of flavors from Maillard reaction in cut tobacco of cigarette and both the bas-ic research and application of Maillard reaction.
