title: [Study on qualitative and quantitative methods for yinhuang liangxiao granule].
abstract: OBJECTIVE
  To establish the quality standard of yinhuang langxiao granule.
  
  
  METHODS
  The Panax notoginseng, Arnebia euchromq, Cornus officinalis, Lonicera japonica, Artemisiae annua were identified by TLC. The content of chrysophanol in granule was determined by HPLC.
  
  
  RESULTS
  Spots of samples on TLC can be well separated and the method had good specificity. The average recovery of chrysophanol was 98.7% and RSD was 0.67%.
  
  
  CONCLUSIONS
  An accurate, simple and effective quality-controlling method has been developed, which can be used for quality control for yinhuang langxiao granule.
