众香子叶油挥发性成分分析及其在卷烟中的应用

为分析众香子叶油挥发性成分及其在卷烟中的应用效果,采用同时蒸馏萃取与毛细管气相色谱-质谱联用技术检测众香子叶提取物挥发性成分,共分离出36种成分(占总峰面积的91.43%),并确认了其中的29种成分,之后采用面积归一化法测定了各种成分的含量,其主要成分为:丁香酚(30.84%)、4-甲基-5-(3-甲基-5-异恶唑基)-噻唑(11.86%)、异丁香酚(10.44%)、桉树脑(6.01%)、1,5,5,8-四甲基橙花叔醇(3.64%)等。卷烟加香试验结果表明:众香子叶油能有效掩盖卷烟杂气,使烟气柔和、香气细腻,明显改进烟气质量,其中施加量为0.02%时效果较佳。

Analysis of Volatile Components in Pimenta dioica Leaf Oil and Its Application in Cigarette

In order to analyze volatile components in Pimenta dioica leaf oil and its application in cigarette,the aroma components of Pimenta dioica were extracted by simultaneous distillation and extraction equipment(SDE).Thirty-six aroma components were isolated by capillary GC-MS method,amounting to 91.43% of total mass fraction,and 29 compounds of them were identified.The relative contents were determined by area normalizing method,indicating that the main flavor compounds were eugenol(30.84%),4-methyl-5-(3-methyl-5-isoxazolyl)-thiazole(11.86%),isoeugenol(10.44%),cajeputol(6.01%),1,5,5,8-methyl nerolidol(3.64%),etc.In the tobacco flavoring experiment,it showed that extraction of Pimenta dioica could efficiently reduce offensive odor,make tobacco smoke smooth and fine,and improve smoking quality of the cigarettes.
