[Meth- od] On the basis of determining ICP-MS working curve ，由e contents of 8 heavy metals in licorice from 7 places were measured , and the deter- mination results were compared to h四vy metal standard in Chinese Pharmacopoeia 2010 Edition. [Result] Heavy metal in licorice accounting for 42. 863品， meets the standard of Chinese Pharmacopoeia 2010 Edition , among which As , Pb , Hg are the main factors causing heavy metals exceeding standard. [Conclusion] Heavy metal content in licorice is related with 也at in soil , fertilizer and moisture , relevant quality inspec- tion departments should deeply investigate licorice origin ，回国 to find out exceeding re幽ons for heavy metal contents in licorice.
