【Abstract】 In the present paper, a methodin which chromatopyrography, capillary gas cbro-matogrsphy and mass spectrometry were coupled on-line and used for analysis of Chinese medi-cinal herbs is described. The experimental results showed that it proved to be a convenient tool for identification and evaluation of medicinal herbs. The herbs studied were Angelica sinensis (Otiv.), Mentha haplocalyx Briq. and Eugenia caryophyllata Thunb.更多还原
