To determinate the content of heavy metals in Rhizoma Curcumae Longae，and to provide reference for the establishment of heavy metal limit standards for Rhizoma Curcumae Longae medicinal materials.Methods:The contents of Cu，As，Cd，and Pb in 27 batches of Rhizoma Curcumae Longae samples were determined by inductively coupled plasma mass spectrometry (ICP-MS).Results:There were significant differences in the content of heavy metals in Rhizoma Curcumae Longae medicinal materials from different producing areas，the contents of Cu，As，Cd and Pb in Rhizoma Curcumae Longae samples were 2.62~9.34 μg/g，0.03~0.60 μg/g，0.01~5.39 μg/g，0.106~2.04 μg/g.Among the 4 heavy metals，only Cd exceeded the standard，and the rate of over-standard was 40.7%.Conclusion:The Cd in Rhizoma Curcumae Longae is seriously polluted，and some Cd pollution of Rhizoma Curcumae Longae has reached moderate or severe pollution.It is recommended to establish a limited standard for heavy metals in Rhizoma Curcumae Longae，and to provide a basis for the standard planting and safety evaluation of Rhizoma Curcumae Longae.
