Abstract:
Eleven kinds of drug including (Vc) Qiangliyinqiao, Huanglianshangqing, Sanhuang, Ganmaoqing, Fufangchuanxinlian, Biyankang, Banlangenchongji, Niuhuangjiedu, Zhongganpian, Shuanghuanglian Koufuye and Qingrejiedu Koufuye are digested with HNO3-HClO4 mixed acid. The ten trace elements of copper, iron, zinc, manganese, cobalt, nickel, calcium, magnesium, cadmium and lead in the solution are determined by atomic absorption spectrometry. The results obtained show that antipyretic and antidote contains higher amount of Ca, Mg, Fe, Zn and Mn than other elements.
