[Objective] To determine the contents of trace eleraents in Potentilla discolor Bge of traditional Yi medicine, so as to provide refer-ences for the development and application of P. discolor. [ Method] P. discolor sample was digested by microwave with concentrated nitric acid. Then, Fe, Cu, Zn, Mn, Ca and Mg contents in P. discolorr sample were detected by FAAS, [Result] P. discolor was rich in various essential trace elements for human body. This method had good linear relationship ( R = 0. 995 7 - 0.998 2) ; the average recovery rate was 96.4% - 107% ( n = 8 ) ; and RSD was 1. 9% - 5.5% ( n = 8). [ Conclusion ] This method was simple and accurate and could be used for the rncontinuous detection of many dements in P. discolor.%[目的]测定彝药翻白草中微量元素的含量,为其开发利用提供依据.[方法]先用浓硝酸微波消解翻白草样品,然后用火焰原子吸收光谱法测定翻白草中Fe、Cu、Zn、Mn、Ca和Mg 6种元素的含量.[结果]翻白草中含有丰富的人体必需微量元素,该方法的线性关系良好(R =0.9957～0.9982),平均回收率在96.4％～107％(n=8),RSD在1.9％～5.5％(n=8).[结论]该方法简单、准确,可用于彝药翻白草中多种元素的连续测定.
