Comparison of Total Flavonoids in Erigeron breviscapus(Vant.) Hand Mazz. from Different Habitats

[Objective] To compare the contents of total flavonoids in Erigeron breviscapus (Vant.) Hand Mazz. from different habitats. [Method] Contents of total flavonoids in Erigeron breviscapus from nine places were determined by UV method, and subjected to variance analysis. [Result] The highest content of total flavonoids per plant reached 18.539%, and the lowest was 3.563%; the average content of total flavonoids in Erigeron breviscapus was the highest from Mangbang Village of Tengchong County, while that was the lowest from Xueshan Village of Luquan County. There are great differences among the individuals from the same habitat with the largest variation coefficient of 25.6%, and the smallest variation coefficient of 9.7%. Variance analysis (F=19.467,P=0.000 1<0.01) and least significant difference (LSD) multiple comparison proved that there are significant differences of total flavonoids content in Erigeron breviscapus among different habitats. [Conclusion] Content of total flavonoids in Erigeron breviscapus is influenced by both heredity and growth environment, which provides evidence for the selection and breeding of improved Erigeron breviscapus.
