摘　　要：采用超临界CO2流体萃取法(SFE)与水蒸气蒸馏法(SD)从山柰中提取挥发油.用气相色谱-质谱联用技术对化学成分进行分析,用归一化法测定其相对百分含量.超临界CO2流体萃取法提取的挥发油共鉴定了39种成分,占挥发油总成分的86%以上;水蒸气蒸馏法提取的挥发油共鉴定了51种成分,占挥发油总成分的89%以上.研究表明超临界CO2流体萃取法提取的挥发油能更真实、全面地反映药材中的化学成分.Essential oil was extracted from Kaempferia. galanga L by supercrifical fluid extraction （SFE） and steam distillation （SD）. The extracted components were determined by gas chromatography with area noramlization method, and were identified by gas chromatography-mass spectrometry. There are 39 components separated and identified from Kaempferia. galanga L by SFE, which compose of about 86% of the total essential oil. There are 51 components seperated and identified from Kaempferia. galanga L by SD, which compose of about 89% of the total essential oil. The result shows that SFE method can reflect the chemical components of the medicinal materials more accurately and more comprehensively.
