The objective of this study was to investigate the content of main mineral elements in cultivated fruiting bodies of Cordyceps militaris. Microwave digestion was used to pretreat Cordyceps militaris samples, and the content of seven mineral elements in Cordyceps militaris was determined by inductively coupled plasma mass spectrometry (ICP-MS). The results showed that the content of arsenic (As), lead (Pb) , cadmium (Cd), copper (Cu) , silver (Ag), zinc (Zn), and manganese (Mn) in cultivated fruiting bodies of Cordyceps militaris, respectively, is 0.0047 mg/kg, 0.22 mg/kg, 0.0041 mg/kg, 9.1 mg/kg, 0.024mg/kg, 5.2mg/kg, and 1.6 mg/kg. The content of heavy metals such as Pb, Cd and As is within the limits of Chinese national food safety standard. The method used in this study has the advantages of high sensitivity, fast analysis speed, and good reproducibility. It can be used for the determination of mineral elements in cultivated fruiting bodies of Cordyceps militaris.
