摘　　要：目的:探讨苍术超临界提取物炮制前后的成分变化。方法:采用GC-MS(gas chrom atography-mass spectrometer)分析南北苍术炮制前后的超临界CO2萃取物。结果:从南苍术和北苍术炮制前后SFE-CO2萃取物中分别确定30、33种化合物。在相对含量较高的成分中,南苍术经麸炒后有12个成分含量下降,7个成分含量上升;北苍术经麸炒后有10个成分含量下降,11个成分含量上升。结论:苍术经麸炒后,低沸点的成分含量有下降趋势,高沸点成分含量有升高趋势。Objective： To analyze the chemical constituents of the volatile oil by SFE-CO2 from Rhizoma Atractylodis and its roasted products. Methods： The chemical constituents of the volatile oil extracted by SFE-CO2 were separated and identified by GC-MS. Results ： 33 kinds of constituents were identified from Atractylodes lancea （ Thunb. ） DC. and its roasted products. The relative contents of 12 kinds of constituents from the processing products were descended and 7 kinds were ascended; 30 kinds of constituents were identified from Atractylodes chinensis （ DC. ） Koidz. and its roasted products. The relative contents of 10 kinds of constituents from the roasted products were descended and 11 kinds were ascended. Conclusion： In the processed products, the relative contents of some low boiling point constituents are descended but some high are ascended.
