[Objectives]To evaluate the quality of Atractylodes chinensis(DC.)Koidz.in Chengde region.[Methods]35 samples of A.chinensis from different growth years were collected,and a high performance liquid chromatography(HPLC)method was established for the dual components of atractylodin and atractylone,and the quality evaluation was conducted on the cultivated A.chinensis from Chengde region in terms of moisture,ash and volatile oil content.[Results]The moisture content of all samples met the regulations,and the content of volatile oil was relatively high.Among them,seven samples with atractylodin content lower than 0.3%were unqualified products(accounting for 20%),and one sample had excessive ash content(accounting for 3%).[Conclusions]The established method for the determination of the dual components of Atractylodis Rhizoma is stable,simple,fast,precise and reusable.Besides,according to the Pearson correlation analysis among the indicators,it is concluded that the atractylodin and atractylone content are significantly related to the growth period and the volatile oil content.In addition,the quality evaluation indicators of A.chinensis in Chengde region show that there are differences in the quality of Atractylodis Rhizoma,but the overall pass rate is relatively high.It is necessary to further study the reasons for the differences.
