4种治疗胃炎中成药中铁、锰的形态分析

Speciation analysis of Fe,Mn in 4 kinds of treatment gastritis Chinese traditional medicines

治疗胃炎的养胃舒、温胃舒、胃康灵、三九胃泰4种中成药采用混合酸[V（HNO3）＋V（HClO4）=4＋1]消化，用LSA—10树脂分成有机态和无机态．用火焰原子吸收分光光度法测定了Fe、Mn各形态的含量．结果表明，Fe、Mn元素基本可溶，Fe以无机态为主，Mn以有机态为主．样品的加标回收率在92．0％～108％之间，方法可行．

The four Chinese traditional medicines of Yangweishu, Wenweishu, Sanjiuweitai and Weikangling were digested by HNO3 and HClO4（4：1）. The organic form and inorganic form were separated by LSA-10 adsorptive resin and the content of every state was determined by atomic absorption spectrometry. The results show that the two elements were in soluble state. Mn exits in the form of organic speciation, and most of Fe exits in the form of inorganic speciation. The recovery for the method was 92.0 %- 108 %. It shows that the result is satisfactory.
