It provides a scientific basis for quality control and clinical safety in the production of Chinese medicinal materials. Methods An Inductivety Coupled Plasma-Mass Spectrometry method with Microwave-Assisted Digestion was developed with Se, Y, In, In-1 and Bi as internal standard. Results For the determination of each element, the correlation coefficients were better than 0.998 0-0.999 9, the recovery values ranged from 88.0% to 107.3%, and the RSD values ranged from 0.1% to 11.0%.Conclusion The method is simple, rapid and accurate, and can be used for the determination of 17 elements in Chinese medicinal materials."/>
