Objective: To discuss the characteristic of the contents of inorganic elements in samples of Dioscorea nipponica and the soil in which the crude drugs were planted

and explore the correlation between them. Method: The contents of 13 elements in ten D. nipponica samples and ten soil samples were determined by means of ICP-MS. The results were provided for calculate the correlations by SPSS. Result: There were no significant correlations between the crude drug and its relevant soil. The most conspicuous accumulation of elements was K

the others were Ni

Hg

Mg

Zn

Cu

Cd

subsequently. Specially

the sample of Jiamusi

Heilongjiang province had the strongest ability to accumulate every element that it can do. And there were multi-correlations among some elements in the crude drug. Conclusion: The majority of pathway of inorganic element absorption are selective absorption in D. nipponica . The coordination among elements is in favor of the accumulation of elements in D. nipponica .
