Abstract：The present research aimed to establish a kind of simple and rapid method to detect metal elements in Cortex Spondiacis were determined by microwave digestion and inductively coupled plasma mass spectrometry (ICP-MS). The sample was digested with HNO3-H2O2 acids system. The operation would be simplified and the blank value would be decreased with the above acids systems. Instead of using concent rated acid, this experiment not only can leave out the process of drying or dilution and save time, and extend the life of the instrument, but also eliminates the errors of the inconsistency between digestion solutions and standard solutions. The experimental results showed that Cortex Spondiacis is rich in beneficial elements such as potassium, calcium, magnesium, iron, sodium, and nickel. And the content of harmful elements of the drug, such as mercury, lead, cadmium and arsenic, is under the national rule, which have some medicinal value. Under the optimum working conditions of the instrument, the detection limits were all smaller than 0.052 1 μg·L-1, the recovery ratios by standard addition were in the range of 90.8%～113.8% and the RSD was smaller than 5.10% for all elements. Precision and accuracy of determining results are satisfactory. This results are reliable. These results are reliable. The method can meet the need for simultaneity determination of high content element and trace element in Cortex Spondiacis.
