The flame atomic absorption spectrometry was used to measure the contents of Fe, Cu, Zn, Mn and Mg in the digestion solution of Tartary buckwheat. ［Result］ Mg content was higher in Tartary buckwheat. The recovery ratio of each element was during 94.8%-101.5%, and the result was satisfactory. ［Conclusion］ The method was simple, convenient, quick and accurate. It had the good repeatability and could satisfy the requirement of routine analysis and detection.
