Abstract:
During the study of the Mongolian medicine, we found that the Mongolian medicine contains great amount and a variety of trace elements needed for human body, but the heavy metals are very little. A method for the determination of Ca, Cu, Zn, Fe, Mg, Mn and Pb in the Mongolian medicine. (1# the morning medicine, 2# the noon medicine and 3# the evening medicine.) by ICP-AES with microwave, digestion was studied. The recoveries of standard addition are in the range of 94.63%-106.40%. The relative standard deviation is < or = 3.41, and detection limit is in the range of < or = 0.009 microg x L(-1). The results show that 1#, 2# and 3# are different kinds of medicine with some difference in the trace elements quantity, but can cure hyperlipidemia disease by their combination.
