To use 3 components of eucalyptus，camphor and borneol to evaluate Artemisia argyi from “wan ai” and other producing areas，providing technical support for the quality control of Artemisia argyi and the construction of genuine medicinal materials base.Methods:Agilent HP-5 capillary column(30 m×0.32 mm×0.25 μm)and FID detector(hydrogen flame ionization detector)were used.Determination was by Gas Chromatography Temperature Program.Results:There were significant differences in the content of the 3 components in the 32 producing areas.The content of eucalyptus in Nanyang Tongbai Artemisia argyi leaves was higher，the content of camphor in Nanyang Zhenping Artemisia argyi leaves was higher，and the content of borneol in Hebei Anguo Artemisia argyi leaves was higher.Conclusion:The method is simple and reproducible，it can be used for quality evaluation of Artemisia argyi leaves.Quality research of Artemisia argyi leaves provides technical support for the production base of genuine medicinal materials in Nanyang area.
