| 摘 要： | 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=0.995 7～0.998 2),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。

| Abstract: | Objective] To determine the contents of trace elements in Potentilla discolor Bge of traditional Yi medicine,so as to provide references 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.discolor 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 continuous detection of many elements in P.discolor. |
