title: [Determination of entrapment efficiency of breviscapine nanoliposomes].
abstract: OBJECTIVE
  To determine the entrapment efficiency of breviscapine nanoliposomes.
  
  
  METHODS
  Retrodialysis method was used to determine the entrapment efficiency of breviscapine nanoliposomes. The drug recovery and the sample recovery were considered to verify the feasibility of the method.
  
  
  RESULTS
  The drug recovery was (99.6 +/- 0.6)%. The sample recovery was (99.9 +/- 0.8)%. The entrapment efficiency of breviscapine nanoliposomes was (75.3 +/- 2.3)%.
  
  
  CONCLUSIONS
  The method used in this study is simple, applicable and accurate for determination of the entrapment efficiency of breviscapine nanoliposomes.
