【Abstract】 In present paper, the principal volatilc constituents of Chinese medicinal herbs, Curcuma longa L., A. lancea(Thunb.)DC.,Foeniculum vulgare Mill. And cinna-momun cassia presl have been analyzed by means of flash distillation/capillary gas chromatography/mass spectrometry. The results obtained were similar to that of conventional steam distillation-extration method. But this new technique possesses such advantages: rapidity, simple manipulation, micro quantity of plant sample used and the exclusion of interference from impurities in the extrating solvents. It proves to be a promising tool for analysis of volatile constituents of natural products. The optimum condition of flash distillation has also been studied.更多还原
