Abstract：The contents of rare earth element( REE) of Pseudostellaria heterophylla and planting soil were measured in Wudang district of Guiyang city,and the correlation between them was analyzed. The results showed that the REE content distribution in Pseudostellaria heterophylla and planting soil followed the Od-do-Harkins law,the REE content distribution pattern in Pseudostellaria heterophylla was very similar to that in planting soil,and was significantly related with that in planting soil;the REE content distribution rule in planting soil was consistent with the distribution rule of Chinese REE background value and avera-ge value in soil; the enrichment capacity of Pseudostellaria heterophylla was lower for REE in soil, the REE bioconcentration factors were only from 0 . 003 to 0 . 021; Pseudostellaria heterophylla was harmless and could be safely used as either medicine or edible through the analysis of the REE content;the REE content of Pseudostellaria heterophylla had some inheritance from planting soil through the analysis of the REE distributional pattern,fractionation of LREE and HREE,and the REE content.
