摘　　要：在对人工林杉木进行高温热处理的基础之上,采用常压水蒸气蒸馏法对杉木热处理材中的精油含量进行了测定,并采用气质联用仪对未处理材和经过160、220℃处理材的精油组分进行了分析。研究结果表明:当热处理温度分别为120、140、160、180、200、220℃时,所对应的杉木脱油率分别为0.855%、13.516%、16.189%、39.156%、41.063%、58.739%;热处理温度对杉木精油主要组分的相对含量有较大影响,其中α-柏木烯、柏木醇的相对含量分别由未处理时的5.4104%和69.2391%变化到220℃时的45.482 5%和31.089 5%。This Essential oil was distillated from high temperature heat treated Chinese fir wood by normal pressure steam distillation and its content was determined.Also,the extracted essential oils from untreated and treated samples at 160℃and 220℃respectively were analyzed by using GC-MS.The results revealed that：as treating temperatures varied from 120℃,140℃,160℃,180℃,200℃to 220℃,the relative de-oil ratios were 0.855%,13.516%,16.189%,39.156%,41.063%,and 58.739%; the treatment temperature had a great effect on the essential oil content,among which the relative contents ofα-cedrene and cedrol changed from 5.410 4%,69.239 1%before treating to 45.482 5%, 31.089 5%after being treated at the temperature of 220℃,respectively.
