Aim:To establish the methods for detection of heavy metal contents in the Scoparia dulcis L from Hainan province. Methods:The contents of As, Hg, Pb, Cd were detected by hydride generation a-tomic fluorescence spectrometry. Results:The linear correlation coefficients of As, Hg, Pb, and Cd were 0. 9991 - 0. 9999; the precisions were less than 2. 74% ; the recovery was 95% - 102. 3% with RSD of less 3. 36% . Levels of heavy metals in the Scoparia dulcis L. were within the extent of green standard for traditional Chinese medicine. Conclusion:The detection method is accurate, reliable, quick and smiple for the quality control of the Scoparia dulcis L. .
