    Project was supported by the Key Science and Technology Innovation Team of Zhejiang Province(No.2011R09002-11)and the Opening Foundation of Zhejiang Provincial Top Key Discipline(No.200908).

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.

Key words: Curcuma zedoaria Rosc., flash evaporation, gas chromatography, principal component analysis, hierarchical cluster analysis
