title: [Determination of tetrandine content in tetrandine microsphere].
abstract: OBJECTIVE
  To determine the contents of tetrandine in tetrandine microsphere for the quality control of the preparation.
  
  
  METHODS
  Tetradine in microsphere was determined by spectrophotometry of standard curve.
  
  
  RESULTS
  The content of tetrandine was 44.5% +/- 0.26% (n=3).
  
  
  CONCLUSIONS
  The method was simple, rapid and accurate.
