摘要
采用HNO3 HClO4 (4∶1)混酸消化用于治疗糖尿病的消渴丸、玉泉丸、渴乐宁、降糖舒、降糖Ⅰ—Ⅴ号9种中成药 ,用原子吸收光谱法对药物消化液中的Cu ,Zn ,Ni,Co ,Mn ,Cr ,Mo,Fe,Ca,Mg ,Cd ,Pb12种微量元素进行了分析测定。该方法的加标回收率为 97%～ 10 5 % ,相对标准偏差 (RSD)小于 5 % ,具有良好的准确度和精密度。结果表明 :糖尿病类中成药中除Cd ,Pb外 ,其余 10种元素的含量均较为丰富。
The 9 kinds of Chinese traditional medicines which are used to cure diabetes including Xiaokewan, Yuquanwan, Kelening, Jiangtangshu, Jiangtang Ⅰ-Ⅴ are digested with HNO 3-HClO 4(4∶1) mixed acid.The 12 trace elements of copper, zinc, nickel, cobalt, manganese, chromium, molybdenum, iron, calcium, magnesium, cadmium and lead in the solution are determined by atomic absorption spectrometry.Its recovery ratio by standard addition is 97%-105%, and RSD is lower than 5%. This method has good accurate.The results obtained show that except Cd and Pb all other ten trace elements contents in the drug are high.The results of this paper provide useful data for studying the relation between the contens of these trace elements and the medical effect.
