摘要
[目的]测定消食类中草药中Fe、Mn、Zn、Cu 4种微量元素的含量。[方法]硝酸＋高氯酸（4＋1）消解样品,火焰原子吸收光谱法测定样品中4种微量元素的含量。[结果]几种中草药中Fe、Mn、Zn、Cu 4种微量元素含量丰富,RSD〈1.99%,回收率在95.32%~104.00%,结果满意。[结论]该研究为开发新药和药物用量提供了微量元素含量依据。
To determine the contents of Fe,Mn,Zn and Cu in digestion-promoting Chinese herb. [Method]The samples were digested with HNO3＋ HClO4（4 ＋1）,and the contents of four microelements in samples were determined by FAAS. [Result]The microelements were rich in digestion-promoting Chinese herb,RSD 1. 99 %. The recovery rate was in 95. 32 %- 104. 0 %,with satisfactory results. [Conclusion]The study provided basis of microelements content for medicine dose and the development of new medicine.
