摘　　要：目的:了解金属元素含量与止血类中药功效的关系。方法:采用混酸体系作为消化液进行样品消解,火焰原子吸收分光光度法测定7种止血类中草药中Fe、Mn、Cu、Zn、Ca和Mg的含量,并选取样品中的仙鹤草对各测定元素做了加样回收试验。结果:被测中草药中Ca、Mg含量普遍偏高,Fe的含量较高,而Mn、Zn的含量较低,Cu的含量最低。结论:止血中药中金属元素含量与其功效间存在一定在相关性。Objective： To discuss the relation between the contents of metal element and the efficacy of the seven kinds of traditional Chinese medicine （TCM） of hematischesis class. Methods： The samples were digested with HNO3-HCl04 with a proportion of 4：1 and then six metal elements, Fe, Mn, Cu, Zn, Mg and Ca were determined by flame atomic absorption spectrometry. Results： The levels of Ca, Mg were the highest, and the level of Fe was higher. The contents of Mn and Zn were lower, and the content of Cu was the lowest. Conclusion ：There is certain relationship between the contents of the six metal elements in the seven kinds of TCM of hematischesis class and their efficacy.
