Objective: Effects of soil inorganic elements on the contents of inorganic elements and paeoniflorin in Radix Paeoniae Rubra were examined.Methods: The contents of paeoniflorin and inorganic elements of soil and the medicinal material were determined

and the data obtained was analysed by SPSS 13.0.Results: Compared with that grown in Weichang

the Radix Paeoniae Rubra grown in Chicheng contained significantly lower contents of paeoniflorin

Sr and Ca

and higher that of Ni

Cr

Cd and Pb

and it's rhizosphere soil also contained significantly higher contents of Cd

Pb

Cr

Ni

Fe

Co

Cu

As

Zn and Hg.In the medicinal material

the content of paeoniflorin had significantly negative correlation with the contents of three elements(Cd

Pb

Ni)

and the contents of four elements(Cd

Pb

Cr

Ni) that had significant correlations every two were negatively correlated with that of Sr.Moreover

for Cd

Pb

Cr

Ni

Se

there were significant correlations between their soil contents and medicinal material contents.Conclusions: Sr could inhibit the uptake of Cd

Pb

Cr and Ni from soil by Radix Paeoniae Rubra

and Ca may have the same action to Cr and Ni.The contents of Cd

Pb

Ni

Cr and Se in the medicine material may be greatly effected by their contents in soil

and the content of paeoniflorin may be effected by the contents of Cd

Pb and Ni in the soil.
