中文摘要: 建立了测定金鸡胶囊中Ca、Mg、Mn、Fe、Cu、Zn和Sr 7种无机元素含量的分析方法。采用浓硝酸和高氯酸(8+2)的混合酸溶解样品，利用电感耦合等离子体原子发射光谱法(ICP-AES)对各种元素进行测定。金鸡胶囊含有丰富的对人体有益的无机元素，对待测样品的测定结果表明，Ca、Mg、Fe、Mn、Zn、Sr和Cu的含量分别为16356、8525、714.3、234.7、52.49、34.69和20.70 μg/g。各元素的回收率在95.5%～104.8%之间(n=3)，相对标准偏差RSD在1.4%～6.2%之间(n=6)。该方法简便、快速，测定结果准确可靠，可用于中成药中多元素的同时测定。

Abstract:A method for determination of seven inorganic elements(Ca, Mg, Mn,Fe, Cu, Zn, and Sr) in Jinji Capsules has been developed. The sample was digested with the acid mixture of HNO3+HClO4 (8+2) and then was analyzed by inductively coupled plasma atomic emission spectrometry (ICP-AES). The results showed that there were many kinds of inorganic elements good to human being health in the Jinji capsules. These elements include Ca, Mg, Fe, Mn, Zn, Sr and Cu and their contents were determined as 16356, 8525,714.3, 234.7, 52.49, 34.69 and 2 0.70 μg/g, respectively. The recovery ratios for each element determined by standard addition method were in the range between 95.4% and 104.8%(n=3); and relative standard deviation (RSD) were in the range between 1.4% and 6.2% (n=6). It concluded that the method was simple and rapid, the results were accurate and reliable. It can be used for simultaneous determination of multiple elements in Chinese traditional patent medicine.
