摘　　要：目的:对石香薷和海州香薷中挥发性化学成分进行研究。方法:采用顶空固相微萃取-气相质谱联用技术对2种香薷植物挥发性成分进行提取分离和鉴定研究。结果:从海州香薷和石香薷挥发性成分中分别检出39,46种成分,分别占挥发性成分总峰面积的70.50%,92.44%。结论:香薷挥发性成分中主要含高级烷烃、烯烃、醇、酮、酚及有机酸等多种化学成分,具有较高的医药、食品应用价值,为香薷资源的进一步开发利用提供了科学依据。Objective： To study the volatiles from Elsholtzia splendens and Molsa chinese. Method： The volatile chemical constituents from E. splendens and M. chinensis, were analysed by HS-SPME-GC-MS. Result：Thirty-nine and forty-six components from E. splendens and M. chinese, which accounted for 70. 55% and 92.44% of the peak areas, were separated and identified. Conclusion： The volatile chemical constituents have high application value in medicine and chemical industry and mainly consisted of alkane, olefin, alcohol, ketone, phenol, organic acid, etc. The present experiments provide a scientific basis for the further exploitation and utilization of this herb.
