Abstract：A method was studied for the analysis of 11 kinds of trace elements(Cr, Mn, Ni, Co, Cu, Zn, As, Se, Mo, Cd and Pb) in root-like and rootstalk-like dried medicinal herbs by microwave digestion-ICP-MS. A digestion method was developed for trace elements analysis for two types of herbs. The Microwave digestion condition was optimized in terms of digestion system, proportion of acids, and digestion procedure, which affords reference to the preparation of the same kinds of dried medicinal herbs. The detection limits of the method for all sample elements were in the range of 0.001-0.260 μg·g-1, the RSDs were between 0.4%-3.1% and the recoveries were between 90% and 110%.
