摘　　要：[目的]分析研究光果莸不同器官中挥发油的化学成分。[方法]采用水蒸气蒸馏法提取光果莸挥发油,通过气质色谱-质谱(GC-MS)联用技术进行挥发油的成分分析。[结果]通过计算机检索、保留指数鉴定出光果莸不同器官中挥发油的化学成分分别有42(叶)、21(枝)和29种(根)。含量最高的分别是β-蒎烯(32.19%)、古巴烯(21.09%)和反松香芹醇(15.66%)。[结论]光果莸3种不同器官的挥发油在成分构成上比较相似,但在相对含量上差异较大。[ Objective] To analyze the chemical constituents of essential oil in different organs of Tibetan medication Caryopteris tanguttca. [ Method ] The essential oil of Caryopteris tangutica was extracted by steam distillation and analyzed by gas chromatography-mass spectrometry （GC-MS） and retention index. [ Result] 42 compounds were identified in the leaves, 21 in the branches and 29 in the roots respectively. The content of {3-Pinene（32.19）, cL-Copaene（21.09% ） and trans-Pinocarveol（15.66） were the highest among the three organs. [ Conclusion] The essential oil in three different organs of Caryopteris tangutica shows a similarity in chemical components but a high difference in relative contents.
