| Abstract: | The objective of the paper is to determine the amount of metal elements of K, Mg, Ca, Cu, Zn, Mn, Fe, Co, Cd, and Pb in Astragalus and Lanceolata by flame atomic absorption spectrophotometry, The samples were digested by dry process and wet process with nitric acid-perchloric acid 4 ： 1 （V/V） at 90-95 ℃ and nomlal pressure separately. The analytical results showed that all samples come up to standard of the heavy metals according to tile issued standard of World Health Organism. The characteristic method is quick, simple and convenient and the results are satisfactory. |
