Objective: To analysis of nine kinds of trace elements essential to human in different regions and assess the quality of Impatientis Semen. Method : The content of trcae elements was determined by ICP-MS

the correlation between the content of trace elements in Impatientis Semen was analyzed by SPSS and principal components analysis (PCA) was used to evaluate the quality. Result : The content of useful supplement of Fe

Zn

Mn

Cu was higher. There was significant correlation between different elements. Comprehensive function made by PCA was F=0.209x1+0.256x2+1.194x3+0.236x4+0.267x5+0.044x6+0.196x7-0.084x8+0.263x9. Conclusion : These elements take part in the pharmacodynamic functions of Impatientis Semen and the content of trace elements in different regions was significant different.
