title: [Determination of 2,3,5,4'-tetrahydroxystilbene-2-O-beta-D-glucoside in yangan oral liquid by HPLC].
abstract: OBJECTIVE
  To establish the determination method of 2,3,5,4'-tetrahydroxystilbene-2-O-beta-D-glucoside in Yangan Oral Liquid.
  
  
  METHODS
  2,3,5,4'-tetrahydroxystilbene-2-O-beta-D-glucoside was determined by HPLC on C18 column, in acetonitrile-water (14:86) solution as a mobile phase, detection wavelength as 320 nm.
  
  
  RESULTS
  This method showed a good linear relationship. The average recovery was 99.05% and RSD was 1.31%.
  
  
  CONCLUSIONS
  The method was simple with styong specificity and good repriducibility and can be used for quality control for Yangan Oral Liquid.
