摘　　要：蒙药含有丰富的微量元素，特别是人体必需的微量元素含量较高，而人体有害的重金属元素含量较低。采用微波消解ICP-AES法同时测定了嘎日迪-13（1^#，2^#，3^#）中Ca，Cu，Zn，Fe，Mg，Mn，Pb等15种微量元素。加标回收率在97．5％～105．5％之间，相对标准偏差RSD≤2．90g，检出限≤0．009μg·L^-1。实验结果表明；1#，2^#，3^#具有一定的差异，药的性味功能与微最元素之间也有一定的关系。通过蒙药中微量元素的测定，可以控制配方的准确性及保证产品的质量。In the study of Mongolian medicine the authors found that the Mongolian medicine contains large amount trace elements, and is particularly rich in human-body-needed trace elements, but heavy metals are very little. A method for the determination of Ca, Cu, Zn, Fe, Mg, Mn and Pb in Mongolian medicine Gardi 13（1^# , 2^# , 3^# ） by ICP-AES with microwave digestion was studied. The recoveries of standard addition are in the range of 97.5%-105.5%. The relative standard deviation is ≤2.90, and the detection limit is smaller than ≤0. 009μg·L^-1. The results show that 1^# , 2^# and 3^# are some different, and the smell and function have some relation with trace elements. The authors can control the accuracy of preparation dosage and guarantee the quality of products by determining the trace elements.
