Based on the chemical differences of the volatile oil compositions, C. migao was divided into four chemotype, they were eucalyptol, eucalyptol -cyclohexene, eucalyptol -alpha-terpineol, and eucalyptol -sabinene. The eucalyptol-type was cultivated in Luodian, guizhou province and Funing regions, Yunan province. The eucalyptol-cyclohexene-type was cultivated in Zhengfeng and Wangmo regions, Guizhou province. The type of eucalyptol, eucalyptol -sabinene and eucalyptol -alpha-terpineol were cultivated in Ceheng and Libo regions, Guizhou province.
