title: [Selection of optimal extraction process for huolisu capsule by orthogonal design].
abstract: OBJECTIVE
  To find out the optimal extraction process for Huolisu capsule.
  
  
  METHODS
  The extraction process was studied by orthogonal design with yield of the extracted ginsenoside Re and anthraquinone content determined by RP-HPLC as indexes.
  
  
  RESULTS
  The result showed that the optimal extraction process was 50% alcohol, 8 times the amount of herbs, refluxing for 2 times, each time 2 hours.
