title: [Studies on quality control standard of zhishidaozhi tabloid pills].
abstract: OBJECTIVE
  To develop the quality control standard of Zhishidaozhi Tabloid Pills.
  
  
  METHODS
  Applying TLC to identify Radix et Rhizoma Rhei, Fructus Aurantii Immaturus, Rhizoma Coptidis, Radix Scutellariae, and HPLC to determine the content of emodin of Radix et Rhizoma Rhei.
  
  
  RESULTS
  Radix et Rhizoma Rhei, Fructus Aurantii Immaturus, Rhizoma Coptidis and Radix Scutellariae could be indentified by TLC. Emodin showed a good linear relationship at a rang of 0.0612-0.612 microgram, r = 0.9999. The average recovery was 97.9%, and RSD was 2.1%.
  
  
  CONCLUSIONS
  The methods are accurate and quick, and can be used for the quality control of Zhishidaozhi Tabloid Pills.
