摘要
为揭示中药药性本质，用FAAS测定并比较了十味平性活血化淤中药中微量元素Fe、Cu、Zn和Mn的含量。结果表明，十味活血化淤中药均含有Fe、Cu、Zn、Mn等4种元素，其中Fe、Cu、Zn、Mn的含量范围分别为0．0416～1．2977，0．0025—0．0297，0．2100～0．1501，0．0071～0．7380μg·g^-1。方法加标回收率为98．7％～100．5％，RSD≤2．45％（n=6）。实验方法简便可行，测定结果准确可靠，为后续研究提供了基础数据。
The content of 4 trace elements such as Fe, Cu, Zn and Mn in 10 genera traditional Chinese herbs was determined and compared using flame atomic absorption spectrophotometry. The results showed the average recovery rate was in the range of 98.7% -100. 5%, RSD≤2. 45%. The content range ofFe, Cu, Zn, Mn was that0.0416-1.2977, 0.0025-0.0297, 0.2100-0.150 1 and 0. 007 1 -0. 738 0 μg.g^-1 It concluded this method was simple and feasible, the result was accurate and reliable. The research provides foundation for further study.
