采用动态顶空进样－气相色谱－质谱联用法（DHS －GS －MS）分析不同处理温度（140、160、180、200℃）、不同处理时间（2 h 和3 h）条件下，香柏木挥发性有机物成分及其相对含量的变化。结果表明：对香柏木素材50种目标成分进行分析，萜烯类化合物含量最多，占57.03％；其他成分依次为芳香族类化合物31.67％，醇类化合物5.93％，醛类化合物1.08％，酯类化合物1.01％，酮类化合物0.91％。随着处理温度的升高，芳香族类化合物和醇类化合物相对含量呈下降趋势，萜烯类化合物相对含量呈上升趋势；随着处理时间的增长，芳香族类化合物和萜烯类化合物相对含量呈先增加后减小的趋势，醇类化合物相对含量呈先减小后增加的趋势。

Dynamic Headspace Sampling combined with Gas Chromatography-Mass Spectrometry (DHS-GC-MS)was applied to analyze the changes of the components and relative content of volatile organic com-pounds of Cedrus deodara with high temperature treatment.The treatment was conducted at different tempera-tures (140 ℃,160 ℃,180 ℃ and 200 ℃),with different processing time (2 h and 3 h).The results showed that 50 kinds of main components in untreated Cedrus deodara were identified,and terpenoids,aro-matic compounds,alcohols,aldehydes,esters compounds,and ketones accounted for 57.03%,3 1.67%, 5.93%,1.08%,1.01 % and 0.9 1 %,respectively.The relative contents of aromatic compounds and alco-hols decreased along with the increase of the temperature,while terpenoids increased with the increase of the temperature.The relative contents of aromatic compounds and terpenoids decreased along with the increase of time,which was contrary to that of alcohols.
