摘　　要：在研究蒙古民族的传统医学过程中发现蒙药中含有丰富的宏、微量元素及多种氨基酸等营养成分。人体有益的微量元素含量相对高,而人体有害的重金属元素含量相对低。采用微波消解ICP-AES法同时测定了查格得日(1#和2#)中Ca,Mg,Al,Fe,Mn,Zn,Sr,C和Pb等15种金属元素。加标回收率在97.5%～105.5%之间,相对标准偏差RSD≤2.88%,检出限在≤0.009μg.L-1。实验结果表明;1#和2#具有一定的差异,微量元素与药性、药效之间也有一定的关系。In the study of the Mongolian medicine we found that the Mongolian medicine contains a great amount of trace elements and nutrition composition of amino acids etc, in which trace elements that human body needed are fairly rich but the heavy metals are very little. A method for the determination of Ca, Mg, Al, Fe, Mn, Sr, Cu, Zn and Pb in Mongolian medicine Chagederi （1# and 2# ） 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 42.88, and the detection limit is in the range of ≤0.009μg.L-1. The results show that 1# and 2# have some differences and the medicine property and drug effect has some relation with trace elements.
