Abstract：To study the content and distribution characteristics of mineral elements in soybean from dif-ferent areas of China, the samples from 32 provinces ( cities, autonomous regions, except for HongKong and Macao) were conducted quantitative analysis via ICP-OES technique and the data were evaluated using SPSS principal component and cluster analysis.The results showed that contents of K, Mg, P and S from different regions were relatively stable, while those of Fe, Zn, Mn and Cu had large differences.The mineral element contents in soybean were in the order of K>S>P>Mg>Ca>Fe>Zn>Mn>Cu,and there were certain cor-relations between different elements.Using principal component analysis, 9 kinds of elements were synthesized into 3 principal components, and 32 areas were divided into 2 groups by cluster analysis.It indicated that the mineral element contents in soybean from different regions were various.
