摘　　要：目的:研究桂郁金挥发油的化学成分,为其质量控制提供理论依据。方法:采用超临界CO2法对桂郁金进行挥发油的萃取,并利用气相-质谱联用法(GC-MS)对其组分进行分析鉴定。结果:共鉴定出23个化合物,占挥发油总量的96.83%。结论:桂郁金挥发油主要化学成分是反式-对甲氧基肉桂酸乙酯(55.29%)、3,4-二甲氧基肉桂酸(8.57%)、茴香脑(6.29%)、肉桂酸乙酯(5.23%)。Objective：To study the chemical constituents of volatile oils from Curcuma kwangsiensis to provide the theoretical evidence for controlling its quality.Method： The volatile oils were extracted by supercritical fluid method and analyzed by gas chromatography-mass spectrometry.The relative content of the separated components was determined by normalization method in area.Result： As many as 23 of compounds were identified,containing 96.83%of volatile oils.Conclusion：The main chemical constituents of the volatile oil from C.kwangsiensis are trans-ethyl-p-methoxycinnamate（55.29%）,3,4-dimethoxycinnamic acid（8.57%）,anethole（6.29%）and ethyl cinnamate（5.23%）.
