abstract: OBJECTIVE
  To establish the quality standards for fuyanke(FYK) granule.
  
  
  METHODS
  The phellodendron Chinese schneid, polygonum cuspidatum, sieb. et Zucc and glycyrrihza uralensis fisch in FYK granule were identified by thin-layer chromatography(TLC). The contents of berberine were determined by thin-layer chromatographic scanning(TLCs).
  
  
  RESULTS
  The average recovery rate was 97.86%, and the relative standard deviation 1.96%.
  
  
  CONCLUSIONS
  The method is simple, accurate and reliable.
