title: [Study on quality standard for heshouwu dispensing granule].
abstract: OBJECTIVE
  To study the quality standard for Heshouwu dispensing granule.
  
  
  METHODS
  Heshouwu dispensing granule was identified by TLC and 2,3,5,4'-tetrahydroxy-stilbene-2-O-beta-D-glucoside in Heshouwu dispensing granule were determined by HPLC.
  
  
  RESULTS
  The linear relationship was at the range of 0.4028-3.6252 micrograms and the average recovery was 101.15%, RSD = 2.00% for 2,3,5,4'-tetrahydroxy-stilbene-2-O-beta-D-glucoside.
  
  
  CONCLUSIONS
  The methods were available with a good reproducibility and can be used to control the quality of Heshouwu dispensing granule.
