摘　　要：[目的]研究微波消解-火焰原子吸收光谱法测定湖北延胡索中的金属元素含量.[方法]采用浓硝酸-双氧水处理样品,火焰原子吸收光谱法测定湖北延胡索药材中锂、铍、镁、钛、锰、镍、铬、镉、锌、锡、钠、铝、铜、锶、钡、铅等16种金属元素含量.[结果]延胡索药材中含有丰富的金属元素,试验为探讨延胡索金属元素含量与药理关系提供了有用的数据,各元素的回收率为97.9％ ～ 101.9％.[结论]该方法灵敏度高,操作简单、快速,结果准确,是延胡索药材中金属元素测定的理想方法.[ Objective ] The research aimed to study the determination of metal elements in Corydalis Yanhusuo from Hubei by flame atomic absorption spectroscopy with microwave digestion. [ Method] The contents of sixteen metal elements in Corydalis Yanhusuo, including Li, B, Mg, Ti, Mn, Ni, Cr, Cd,Zn, Sn, Na, A1, Cu, Sr, Ba and Pb, were analyzed by flame atomic absorption spectroscopy after digested by Microwave with HNO3-H2 02. [ Result ] Abundant metallic element was contained in Corydalis Yanhusuo. The experiment provided helpful data to study the reaction between the metal elements of Corydalis Yanhusuo and pharmacology. The recovery of these metal elements was between 97.9% and 101.9%. [ Conclusion ] The method was simple, rapid and the result was accurate, and can applied for determination of metal elements in Co- rydalis Yanhusuo.
