| Abstract: | Objective： To study the contents and distribution of trace elements of Red Kojic on Chinese traditional medicine gathered from different habitats. Method： Principal components analysis and cluster analysis of SPSS are applied for the study of characteristic elements. Result： 4 principal components are obtained, which contributes variance over 90.072%. Based on these principal components, germplasms are clustered into 4 group switch Ward＇s method. Conclusion： The results provide scientific basis for research and identification of Red Kojic. |
