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 5079.641, 2760.188 and 1070.297 mg * kg(-1) respectively. The result of Potentilla parvifolia Fisch can provide theoretical basis for medicine research.
采用原子吸收光谱法对委陵菜中钙、铁、锰、锌、铜和镁的含量进行了测定。该方法的回收率为98.3%-103.2%，相对标准偏差为1.21%-3.01%，具有快速、准确的特点。委陵菜中各元素含量顺序为镁>钙>铁>锰>锌>铜。海拔与含量之间无相关性。镁、钙和铁的平均含量分别为5079.641、2760.188和1070.297 mg·kg(-1)。委陵菜的测定结果可为医药研究提供理论依据。
