title: [Study on quality standard for qiangnaosu capsule].
abstract: OBJECTIVE
  To establish the quality standard for Qiangnaosu capsule.
  
  
  METHODS
  TLC was used for the qualitative identification of Saposhnikoviae Radix, Chuanxiong Rhizoma, Chrysanthemum Flos, Fructus Viticis. HPLC was used to determine the content of ferulic acid.
  
  
  RESULTS
  TLC spots were clear, well-separated and specific. The linear range of ferulic acid was 2.93 - 20.50 microg/mL (r = 0.9996). The average recovery was 98.1% and RSD was 1.42%.
  
  
  CONCLUSIONS
  The method is reliable and specific. It can be used for the quality control of Qiangnaosu capsule.
