title: [Determination of baicalin in banxiaxiexintang decoction different combinations of the by PR-HPLC].
abstract: OBJECTIVE
  To the amount of baicalin in Banxiaxiexintang Decocted of different combinations were determined by PR-HPLC.
  
  
  METHODS
  An YWG C18 column was used with a mobile phase of MeOH-H2O-H3PO4(47:53:0.05) and an UV detector at the wavelength of 274 nm.
  
  
  CONCLUSIONS
  The amount of baicalin decreases when Radix Scutellariae is decocted with Rhizoma Coptidis, Rhizoma Pinelliae and Rhizoma Zingiberis.
