摘要	In the present paper，the authors analysed 10mineral elements in the roots of Rheum tanguticum collected from 30 different habitats．The mean concentration values of the 10 elements decreased as follows：Ca>Mg>K>Fe>Mn>Cr>Zn>Ni>Cu>Se. Ca, Mg, K and Fe were abundant in this herb．Most elements varied over a wide range depending on the different habitats．The mineral element data were evaluated by principal component analysis to reveal the distribution pattern of elements in root．Fourprincipa1components(K-Cafactor, Cu factor, Mg factor and Zn-Se factor)of plant elements were selected．The authors’study provided a new scientific foundation for further studies and general application of this Chinese herb．
