title: [Analysis of cadmium in Cortex Ilicis Rotundae].
abstract: OBJECTIVE
  To study the contents of cadmium in Cortex Ilicis Rotundae and provide evidence for establishing the detection limit of cadmium in its quality standard.
  
  
  METHODS
  ICP-MS was used to determine the contents of cadmium in 18 batches of Ilex L.
  
  
  RESULTS
  The contents of cadmium in 10 batches of Cortex Ilex Rotunda ranged from 3.4 to 10.4 mg/kg,and the contents of cadmium in Ilex asprella and Ilex pubescents were more than 0.3 mg/kg.
  
  
  CONCLUSIONS
  The contents of cadmium of Cortex Ilicis Rotundae, Ilex asprella and Ilex pubescents have particular characterise, and this study provides a basic for the analysis of cadmium in Cortex Ilicis Rotundace and other plants of this genus.
