摘要
[Objectives]The paper was to compare the effects of different initial processing methods on atractylodin content of Atractylodes chinensis.[Methods]The atractylodin content of A.chinensis obtained by different initial processing methods was determined by HPLC.The loss rate on drying was determined by weighing.[Results]In the study of drying methods,the atractylodin content varied significantly among different thicknesses of slices,and the overall content of the product with the slice thickness of 5 mm was higher.Among different drying methods,constant temperature vacuum drying and shade drying of 5 mm slice resulted in the highest content of atractylodin.In the experiment of root impacting,root impacting twice received the best effect,and there was no significant difference in the atractylosin content of A.chinensis between drying in the sun and drying in the shade after root impacting twice(P>0.05).[Conclusions]Constant temperature vacuum drying or drying in the shade with the slice thickness of 5 mm,and root impacting twice is the best initial processing method,which leads to high atractylodin content of A.chinensis and good quality of medicinal materials.
