摘　　要：利用水蒸气蒸馏法提取挥发油,采用GC-MS联用技术结合直观推导式演进特征投影法(HELP)对湖北和江西产香薷的挥发油化学成分进行比较分析。共鉴定出37种化合物,湖北香薷35种,江西香薷19种,分别占总含量的95.16%和96.40%。挥发油主要成分为百里香酚、柠檬烯、β-聚伞花素、百里香酚乙酸酯、香荆芥酚和α-丁香烯。Essential oils of Mosla chinensis Maxim from Hubei and Jiangxi provinces were extracted with steam distillation, separated and detected by GC-MS in combination with heuristic evolving latent projec- tions （HELP）. Meanwhile, comparative analysis of volatile components of the samples tested was done. In total ,37 compounds were identified ,35 for Hubei sample, and 19 for Jiangxi sample, respectively account- ing for 95.16% and 96.40% of the total content. The major constituents of the samples tested were thy- mol, D-1imonene, beta-cymene, thymol acetate, carvacrol and alpha-caryophyllene.
