title: [Studies on extraction process optimization of patrinia scabra Bunge saponins].
abstract: OBJECTIVE
  To optimize the conditions for the extraction of Patrinia scabra Bunge saponins.
  
  
  METHODS
  Orthogonal experimental design and ultrasonic method were employed to examine the conditions for the extraction by determination of saponins.
  
  
  RESULTS
  The optimun condition for the extraction of Patrinia scabra Bunge saponins was as follows: 65% ethanol for 40 minutes, 55 degrees C and 210 watt of ultrasonic efficinecy.
  
  
  CONCLUSIONS
  The extraction method of Patrinia scabra Bunge sponins is simple and efficient.
