Abstract：Determining the content of Ca, Fe, Mn, Zn, Cu and Mg in Potentilla parvifolia Fisch by atomic absorption spectrometry was studied. Recovery and RSD of the method is 98.3%-103.2% and 1.21%-3.01% respectively, and the method is rapid and precise. The order of the content in Potentilla parvifolia Fisch is Mg>Ca>Fe>Mn>Zn >Cu. There is not a relation between altitude and content. The mean of the content of Mg, Ca and Fe is 5 079.641，2 760.188 and 1 070.297 mg·kg-1 respectively. The result of Potentilla parvifolia Fisch can provide theoretical basis for medicine research.
