title: [Simultaneous assay of epimedin A epimedin B, epimedin C and icariin in herba epimedii by QAMS].
abstract: OBJECTIVE
  To establish a new method and validate its feasibilities for quality evaluation of Fructus Epimedii.
  
  
  METHODS
  Four main effective flavones, epimedin A, epimedin B, epimedin C and icariin were selected as analytes to evaluate the quality of Fructus Epimedii. The relative correction factors (RCF) of icariin to the other three flavones were calculated. The method was evaluated by comparison of the quantitative results between external standard method and QAMS method.
  
  
  RESULTS
  No significant differences were found in the quantitative results of three flavones by external standard method and QAMS method.
  
  
  CONCLUSIONS
  It is feasible and accurate to evaluate the quality of Fructus Epimedii.
