| Abstract: | The sample of eupolyphag sinensis walker was digested with nitric acid and perchloric acid.The contents of the elements such as Ca,Mg,Zn,Mn were determined by flame atomic absorption spectrophotometry（FAAS）.The recoveries are in the range of 96.86%—102.46% with the relative standard deviation less than 2.36%,and the results are satisfactory. |
