摘    要:采用火焰原子吸收法对20种补益中药中Zn,Cu,Mn和Fe等微量元素的含量进行了分析测定.该方法的加标回收率为96.8%~104.3%,RSD值小于2.0%,具有良好的准确度和精密度.研究结果表明:补益中药中的Zn,Cu,Mn和Fe含量丰富,补血药中的Fe含量最高,补气药中Zn,Mn和Fe含量较高,补阳药中Zn,Mn含量较高,补阴药中Fe含量较低.此测定结果可为探讨补益中药中微量元素的含量与其药效的相关性提供科学依据.

关 键 词:补益中药  微量元素  火焰原子吸收法

Abstract:The contents of trace elements Zn, Cu, Mn and Fe in 20 kinds of benefit traditional Chinese medicines were determined by FAAS. The recovery rates obtained by standard addition method is between 96.8% and 104. 3%, and the RSD is lower than 2. 0%. The results of the determination show that benefit traditional Chinese medicines are rich in trace elements such as Zn, Cu, Mn and Fe. Hematonic has the highest content of Fe. The content of Zn, Mn and Fe is relatively high in Qi-invigorating drugs. The content of Zn and Mn is relatively high in maletonic, while Yin-nourishing drugs have lower content of Fe. The results will provide scientific data for the study on the elements in benefit traditional Chinese medicines and on their relativity of efficacy of medicine.
Keywords:Benefit traditional Chinese medicines  Trace elements  FAAS
