title: [Determination of trace elements in Mongolian medicine Zidianling curing allergic purpura disease by ICP-AES].
abstract: During the study of the Mongolian medicine Zidianling, the authors found that the Mongolian medicine Zidianling contains great amount of trace elements in which human-body-needed trace elements are fairly much but the heavy metals are very little. A method using ICP-AES with microwave digestion was studied for the determination of 15 elements including Ca, Mg, Sr, Fe, Mn, Zn, Cu, Pb, etc. in Mongolian medicine-Zidianling. The major function of this medicine is clearing away heat and removing toxic substances, and cooling blood to stop bleeding. To explain the Zidianling's clinical effects, the authors chose 260 allergic purpura patients with 140 male and 120 female. The youngest was 6 years old, the oldest was 62 years old. Most of patients were between 6 and 16, accounting for nearly 90%. The results of clinical effects show that 234 patients were cured, roughly 90% of the total number Thirteen patients showed obvious effects (5% of the total number) and 11 had effective cures of illnesses (4.23% of the total number). Two patients had no cures of illnesses (0.77% of the total number). And the integrated effective rate may reach 99.23%. The results show that Mongolian medicine Zidianling has great amount of trace elements and its Sr content is different from other Mongolian medicines and is especially high. The recoveries of standard addition are in the range of 94.63%-106.40%. The relative standard deviation RSD< or = 3.17%, and the detection limit is in the range of < or = 0.009 microg x mL(-1).
