Methods The main traits and chemical compositions of 38 samples of Codonopsis Radix from the different planting areas in Jiuzhaigou County were comprehensively compared by SPSS 17.0 software using principal component and cluster analysis. Results Five principal components whose accumulated variance contribution rate was over 85.604% were obtained. Based on these principal components, 38 samples of Codonopsis Radix from the different planting areas in Jiuzhaigou County were clustered into four groups by within-groups linkage cluster methods. Conclusion Principal component and cluster analysis are reliable to comprehensively evaluate the quality of Codonopsis Radix. Significant differences among these samples from the different planting areas in Jiuzhaigou County are obvious. The standardization of cultivation techniques and application should be speeded up.
