摘　　要：采用顶空固相微萃取-气相色谱-质谱法分离和鉴定莪术挥发油成分,用归一化测定其相对含量。共分离出64个组分,鉴定出57种化合物,其含量占总挥发油组分峰面积98.02%。主要挥发成分及其含量为β-榄香稀(18.73%)、β-榄烯酮(11.03%)、莪术二酮(8.47%)、γ-榄香稀(6.79%)。Components of volatile oil of Curcuma rhizoma were separated and identified by head-space solid phase micro-extraction and GCMS in hyphenation, and their relative contents （in %） were found by the method of normalization. Totally 64 compounds were separated among which 57 compounds were identified and determined, amounting to 98.02% of the total peak areas of the components of the volatile oil. The main compounds found with their relative contents were as follows： β-elemene （ 18. 73 %）,β-elemenone （11.03 %）, curdione （8. 47 %） and γ- elemene （6.79%）.
