| Abstract: | Objective] The aim was to establish the method of determining the content of arsenic,mercury,lead,cadmium of Codonopsis pilosula based on the ICP-MS method.Method] Four heavy metals contents of sample digested by microwave were determined by ICP-MS method.Result] The correlation coefficient of the standard curve of 4 elements were larger than 0.999 2,the recoveries of that were 96.5 %~105.2 %,and the RSD was less than 10.5 %.Conclusion] This method was simple,rapid,accurate,sensitive.It could be used for quality control of medicines and could offer determination method of heavy metal content for different types of chinese herbal medicines. |
