Abstract: This study compared the content of total flavonoids and breviscapine in breviscapus growing in Lijiang of Yunnan province and Zhangye of Gansu province. The breviscapine and total flavonoids in breviscapus were extracted by methanol and ethanol respectively,and determined the contents by UV spectrophotometry. The results showed that the total flavonoids content of breviscapus in Lijiang of Yunnan province was higher than that in Zhangye of Gansu province about 71.8%;the content distribution pattern of flavonoids in plants was as follows:leaf > root > stem. The breviscapine content of breviscapus in Lijiang of Yunnan province was higher than that in Zhangye of Gansu province about 42%. The distribution pattern of erigeron content in plants was:leaf >stem >root. The researches showed that the leaf is the main organ of medicinal value ;As a characteristic medicinal plant in Yunnan province ,the breviscapus is not recommended to be planted on a large scale in Zhangye area of Gansu province. The significance of the study is to provide a reference for the development and utilization of breviscapus,and provide some guidance for its different planting patterns.
