摘　　要：建立了莪术药材的闪蒸-气相色谱法(FE-GC),采用FE-GC测定了3个产地的9个莪术样品.0.4 mg的粉末样品,在200℃下闪蒸,经色谱分离,基于闪蒸色谱图上分离鉴定到的35个共有峰的相对强度,结合化学模式识别即主成分分析和系统聚类分析法对莪术样品进行了鉴别分析.3个产地的莪术样品可以很好地得到区别.本法快速、简便、准确,不失为药材质量控制的良好方法.A method of flash evaporation followed by gas chromatography（FE-GC） was developed for de-termination of volatile components of Curcuma zedoaria Rosc.The Curcuma zedoaria Rosc.samples from 3 different growing places were analyzed on the basis of flash evaporation-gas chromatography（FE-GC）.An amount 0.4 mg of sample powder was evaporated in a micro-furnace pyrolyzer at 200 ℃,and the products formed were introduced into a gas chromatograph equipped with a flame ionization detector or mass spec-trometer.Based on the relative peak areas of 35 peaks in the chromatogram obtained by FE-GC,9 samples of Curcuma zedoaria Rosc.from 3 different origins were clearly classified into 3 categories by two pattern recognition analysis,i.e.principle component analysis and hierarchical cluster analysis.The results proved that it is a simple,rapid and accurate method suitable for quality control of the traditional Chinese medi-cines.
