Objective: By determining the active compositions and other compositions in rhizome of Atractylodes lancea from geoherbs and herbs in main producing areas in order to synthetically evaluate the quality of them. Method: β-eudesmol

atractylon

atractylodinol and atractylenolideⅡ in rhizome of A.lancea in different regions were determined by HPLC. Result: There were great differences in content and quality among different regions of A. lancea. The highest content of β-eudesmol and atractylodinol was found in wild products grown in Yingshan city Hubei Province

while the highest content of atractylon and atractylenolideⅡ was found in maoshan city Jiangsu province. Conclusion: The quality in the main origins was better than that in authentic origin from the content determination of β-eudesmol

atractylon

atractylodinol and atractylenolideⅡ in different places

which provide the basis for industrial development of lancea.
