摘　　要：采用电感耦合等离子体质谱(ICP-MS)法同时测定中药益智仁中Li、B、Mg、Al、P、Ca、Ti、V、Cr、Mn、Fe、Co、Ni、Cu、Zn、Sr、Ba、Cd、Pb的含量,以电感耦合等离子体发射光谱(ICP-AES)法测定Ca、Mn的含量,方法的准确性用两个国家一级标准物质GBW10015、GBW10020对比分析证实,精密度实验大部分低于5%。结果表明该法快速简便、准确率高、精密度好,完全可以满足样品中无机元素测定要求。The contents of 19 inorganic elements in Alpinia Oxyphylla Miq.such as Li,B,Mg,Al,P,Ca,Ti,V,Cr,Mn,Fe,Co,Ni,Cu,Zn,Sr,Ba,Cd,Pb were determined by ICP-MS,Ca and Mn were measured by ICP-AES technique.The accuracy of the methods were verified by comparative analysis of the standard reference materials（GBW10015 and GBW10020）,and most of RSDs were lower than 5%.The methods were suitabl to determine the inorganic elements in the sample of Alpinia Oxyphylla Miq.with good accuracy and precision.
