title: [Study on preparaion of nongsuo danggui dispersible tablets and determination of its dissolution].
abstract: OBJECTIVE
  To prepare nongsuo danggui dispersible tablets and determine its dissolution.
  
  
  METHODS
  The dissolution of the tablets was determined by HPLC.
  
  
  RESULTS
  The linear range of ferulic acid was 0.0557 - 0.557 microg (r = 0.9998). The average recoveries met the requirement. Phosphate solution of pH 6. 8 was the dissolution medium.
  
  
  CONCLUSIONS
  The method is simple, accurate and has stronge specificity and can be used for the quality control of nongsuo danggui dissolveing tablets.
