摘　　要：目的:分析薄荷中的挥发性成分。方法:采用水蒸气蒸馏技术采集薄荷的挥发性成分,气相色谱质谱联用(GC-MS)结合保留指数进行分析鉴定。结果:检出70个组分,质谱结合保留指数定性鉴定出36个主要挥发性成分,含量较高的组分为薄荷酮(26.08%)、长叶薄荷酮(11.58%)、β-毕澄茄烯(6.11%)、石竹烯(8.04%)。结论:GC-MS结合保留指数对薄荷挥发性成分进行定性分析,使定性结果更为准确。Objective：To analyze the volatile compounds in herba menthae（HM）.Methods：Using steam distillation,volatile components in HM were analyzed and identified by gas chromatography-mass spectroscopy（GC-MS） combined with Kovats retention indices（KI）.Results：Total 70 components in HM were detected by GC-MS and 36 main volatile compounds were identified by MS combined with KI.Compounds with high contents were as follows：trans-5-methyl-2-（1-methylethyl）-cyclohexanone（26.08%）,pulegone（11.58%）,β-cadinene（6.11%） and caryophyllene（8.04%）.Conclusion：Using MS combined with KI is a accurate way for the identification of volatile compounds in HM.
