摘要：

利用GC/MS结合保留指数分析留兰香油成分, 并用峰面积归一化法计算各组分相对含量。分析并确定33个化合物,占留兰香油成分97.53%,其主要成分为香芹酮(56.19%),柠檬烯(21.26%),-松油醇(4.81%),薄荷酮(2.12%),(Z)-二氢香芹酮(2.01%),芳樟醇(1.42%),-蒎烯(1.46%),-蒎烯(1.16%),3-辛醇(0.84%),莰烯(0.83%),月桂烯(0.69%)等。采用保留指数来鉴别同系物及同分异构体,提高对留兰香油成分定性准确性,研究结果可为留兰香油产品开发和应用提供理论依据。

Abstract: The components in spearmint oil were analyzed with GC-MS and the retention index and peak area normalization method was used to calculate the relative content of each component. Thirty three chemical compounds were identified in the spearmint oil, accounting for 97.53% of all its components. The main components were carvone (56.19%), limonene (21.26%), α-terpineol (4.81%), menthone (2.12%), cis-dihydrocarvone (2.01%), linalool (1.42%), β-pinene (1.46%), α-pinene (1.16%), 3-octanol (0.84%), cmphene (0.83%), and myrcene (0.69%). Cis (trans) isomers were confirmed with the retention index and the accuracy in qualitative analysis of spearmint oil components was improved. The study results have provided technical support for later development and application of spearmint oil.
