Simultaneous Determination of Seventeen Elements in Mongolian Medicine SiweiTumuxiang Powder by ICP-AES

采用电感耦合等离子体原子发射光谱(ICP-AES)法同时测定蒙药四味土木香散中17种常量、微量及重金属元素的含量,并对17种元素加标回收实验进行了研究测定,结果显示在四味土木香散中P和Ca含量较高,富含K、Mg、Na等营养元素,Pb、Cd、Hg、Cu等重金属元素均低于国家标准规定。研究一方面为四味土木香散的疗效寻找依据,另一方面为拓展四味土木香散的应用范围提供有效依据。方法简便快捷、准确、精密度高、重复性较好且稳定。

The contents of seventeen major,minor and heavy metal elements were simultaneously measured,and the recovery tests were also carried out.The results showed that the contents of P and Ca are relatively high,but the contents of Pb,Cd,Hg,Cu,etc are all lower than the national standards.On the other hand,Siweitumuxiang powder is rich in nutrient elements such as K,Mg,Na,etc.This method is simple,convenient and accurate.It has high precision,good repeatability and stability,which providing effect evidence not only for verifying the efficacy of Siweitumuxiang powder,but also for developing its application scope.
