摘　　要：采用超临界CO2萃取和水蒸气蒸馏法提取姜油,用气相色谱-质谱联用技术鉴定了两种提取方法所得姜油的化学成分并进行了分析比较。结果显示:超临界CO2流体萃取法的姜油得率约为水蒸气蒸馏法的3.8倍,提取时间短,温度低,特别是得到了含量较高为12.82%的主要有效成分之一6-姜酚,而在水蒸气蒸馏法得到的姜油中则未见。The ginger oils from rhizome of the Ziniber officinale Rose were extracted by supercritical CO2 fluid （SCF） and steam distillation, the chemical constituents of the oils were analyzed and compared by means of gas chromatography-mass spectrometry. The results showed： compared with steam distillation method, the SCF was quicker in extraction time, lower in extraction temperature and provides 3.8 times higher extraction effieiencies. Particular, one main active ingredient 6 - gingerol with a high relative content of 12.82% was found in the ginger oil extracted by SCF, but it was found without in the ginger oil extraeted by steam distillation.
