title: [Study on preparation technological process of huangqin qingfei koufuye].
abstract: OBJECTIVE
  To study the optimum preparation technological process of Huangqin Qingfei Koufuye for mass production.
  
  
  METHODS
  The optimum technology of extraction HCN from Semen Armeniacae Amarum was selected by experiments; The optimum conditions for the extraction process was selected with orthogonal design, and the content of baicalin in the extract as marker was determined.
  
  
  RESULTS
  The optimum technology of extraction HCN from Semen Armeniacae Amarum was as follows: crushing to pieces, adding 3 times amount of 37 degrees C water and soaking overnight, extracting and collecting 1.33 times amount of extract; the optimum extraction process wasas follows: extracting 2 times, each time adding 12 times amount of water and extracting 1 h.
  
  
  CONCLUSIONS
  The preparation technological process can be used for mass production.
