中文摘要：

利用水蒸汽蒸馏法提取沙漠绢蒿和冷蒿挥发油成分，采用气相色谱-质谱联用法分析鉴定出沙漠绢蒿和冷蒿植物的36种和54种化合物。沙漠绢蒿挥发油主要成分是醇类（24．71％）和酮类化合物（12．69％），其次是芳香族化合物（8．52％）；冷蒿挥发油主要成分是芳香族化合物（39．04％）、醇类（10．78％）和酮类化合物（6．91％）。

英文摘要：

The volatile constitutes of Seriphidium santolinum and Arternisia frigida were extracted by hydro-distillation. The chemical components of volatile oil were separated and identified by gas chromatography-mass spectrometry （GC/MS）. Total of 36 and 54 components were identified from 48 and 60 constituents in the Seriphidiurn santolinum and artemisfa frigida, respectively. The relative contents of components were determined with the peak area normalization method. The major volatile oil constituents in the Seriphidium santolinurn are alcohol compounds （24. 71%）, ketones compounds （12. 69%） and aromatic compound （8.52%）. The major volatile oil constituents in the Artemisia frigida are aromatic compound （39. 04%）, alcohol compounds （10. 78%） and ketones compounds （6.91%）.
