摘　　要：目的:研究香茶菜不同部位挥发油化学成分的差异。方法:水蒸气蒸馏法提取挥发油,利用GC-MS计算机联用仪定性分析,按峰面积归一化法求出挥发油中化学成分的百分含量。结果:香茶菜挥发油主要成分以烷烃、醇、酸、酯为主,香茶菜茎鉴定出8个化合物,香茶菜叶鉴定出24个化合物,香茶菜花序鉴定出17个化合物,香茶菜根鉴定出8个化合物,香茶菜根茎挥发油中鉴定出32个化合物。结论:为进一步开发利用香茶菜提供依据。Objective：To study the differences of chemical constituents of the volatile oils in different fractions from the lsodon amethystoides. Methods ： The volatile oils of Isodon amethystoides were extracted by steam distillation and were i- dentified by GC - MS. The percentage composition of the volatile oils were calculated according to Peak area normaliza- tion method. Results ：The major constituents of the volatile oils were alkanes, alcohols, acids and esters. 8 compounds were identified from the stems, 24 from the leaves, 17 from the inflorescences, 8 from the roots, and 32 from the rhizo- rues. Conclusion：It provides a basis for further development and utilization of Isodon amethystoides.
