title: [Studies of preparing procedures of Yuhuangliang].
abstract: OBJECTIVE
  To optimize preparing procedures of Yuhuangliang.
  
  
  METHODS
  The single factor experimets and the L9 (3(4)) orthogonal design were used to optimize the preparing procedures of Yuhuangliang with contents of berberine and total alkaloids as evalustion index.
  
  
  RESULTS
  The optimal preparing method was Rhizoma Coptidis adding amount of 10 mL (0.2 g/mL) juice of wuzhuyu mixed thoroughly, baking at 100 degrees C, for 15 min.
  
  
  CONCLUSIONS
  The preparing procedure is effective, stable and reliable.
