title: [Experimental studies on compound Duzhong Jiangya prescription by semi-bionic extraction].
abstract: OBJECTIVE
  Optimize the technic condition of Duzhong Jiangya prescription with Semi-bionic Extraction.
  
  
  METHODS
  Using homogeneous design, under the same materials granularity, decoction temperature, consumption of water, filtration, concentration, and taking aucubin, hydrochloric acid stachydrine, maloicacid, baicalin, ethanol extract, dry extract as the indexes, the results were comprehensive considered to optimize the semi-bionic extraction condtions.
  
  
  RESULTS
  The optimized SBE extraction conditions are the following: pH values of the water for the thrice extraction is 5.845 3, 7.496 1, 8.011 7, and the total extraction time is 3.418 0 h.
  
  
  CONCLUSIONS
  Considering the fact of manufacture, the SBE extraction conditions are the following: pH values of the water for the thrice extraction is 6.0, 7.5, 8.0, and the thrice extraction time is 1.5, 1.0, 1.0 h.
