摘　　要：目的:为合理开发使用莪术叶的挥发油成分提供科学依据。方法:用水蒸气蒸馏法提取3种莪术根茎和叶子中的挥发油,进行GC-MS分离测定,利用Nist98标准质谱图库及相关标准品进行对照,鉴定其结构,并测定各成分的相对百分含量。结果:莪术二酮、吉马酮等抗肿瘤活性成分在3种莪术叶子中的含量均较高,甚至远远高于在其根茎中的含量。结论:3种莪术不同部位挥发油成分差别不大,但各成分的相对百分比含量差异明显,可对其叶子进行回收利用。Objective ： To provide the scientific basis for the reasonable development and use of the leaves of Rhizoma Curcumae. Methods： To extract the volatile oil from roots and leaves of three species Rhizoma Curcumae by steam distillation and isolate these products with the method of gas chromatography-mass spectrum. Taking Nist98 standard mass spectrometer database and contrast as control, the structure of the mass spectrogram was identified, and the relative contents of the components were determined with area normalization method. Results： The anti-tumor active constituents such as curdione and germaerone in the leaves had the greater con- tent than in its rhizome. Conclusion ： The varieties of volatile components in different parts of three species of Rhizoma Curcumae are similar, but their contents are obviously various. We can make the leaves of Rhizoma Cureumae for recycling use.
