摘　　要：采用4∶1的混酸体系作为消解液进行样品消解,火焰原子吸收光谱法(FAAS)测定了6种化痰止咳类中草药中金属元素Cu、Mn、Zn、Fe、Ca和Mg的含量。结果表明,6种中草药均含有丰富的金属元素Mg、Ca和较丰富的Fe、Mn,对化痰止咳类中草药的药效起到了促进作用。The content of six elements,Cu,Mn,Zn,Fe,Mg and Ca in six kinds of traditional Chinese medicine that could reduce phlegm and relieve cough,were determined by flame atomic absorption spectrometry.The samples were digested with HNO3-HClO4 with a proportion of 4∶1（V/V）.The result showed that the contents of Mg and Ca were the highest,the contents of Fe and Mn were higher.The high content of certain metal elements can improve the effect of this six traditional Chinese medicine.
