[Objective] To detect the 22 inorganic elements in “ Zuota” grown in Tibet,Qinghai,Gansu and Sichuan Provinces of China; and to analyze their dissolution situation in artificial gastric fluid and artificial intestinal fluid. [Methods] After processed by microwave digestion and treated in artificial gastric fluid and artificial intestinal fluid,22 inorganic elements in “ Zuota” were detected by ICP-OES method. [Results] The 22 inorganic elements in “ Zuota” showed good linear relationship within the range of 0- 20 μg / m L(R2> 0. 999 4). Hg had the maximum content in “ Zuota” among metallic elements. Total Hg had the maximum content in “ Zuota” grown in Tibet,followed with Qinghai and Gansu. And total Hg content was the minimum in Aba of Sichuan. Most of the elements had higher dissolution rates in artificial gastric fluid than those in artificial intestinal fluid. Therefore,it could be concluded that the dissolution part in “ Zuota” was mainly the stomach. [Conclusions] This method could detect many elements at the same time with wide linear range,which was rapid,accurate,simple and sensitive,and could be used for the detection of 22 inorganic elements in “ Zuota”.
