title: [Study on the extraction of polyphenol from Scindapsus officinalis with ultrasonic wave technology optimized by central composite design-response surface method].
abstract: OBJECTIVE
  To optimize ultrasonic extraction technology process conditions of polyphenol from Scindapsus officinalis by the response surface method.
  
  
  METHODS
  Based on ethanol concentration, ultrasonic time, the liquid-solid ratio of single factor experiment, the principle of design for 3 star factor 3 level response surface methodology was applied. With FC extraction method for determination of polyphenols, the response surface optimization extraction conditions were studied.
  
  
  RESULTS
  The ethanol concentration of 61.14%, ultrasonic wave extracting time of 59.73 min and the ratio of solvent volume of 27.72:1 (Extract 3 times) were selected as the optimum conditions,the extraction yield of polyphenols was 1.352%, with the theoretical 1.361% for the relative error of -0.66%.
  
  
  CONCLUSIONS
  Ultrasonic extraction is a good method for saving time, energy and material,and can be applied to the polyphenols extraction. Central composite design-response surface optimization can get better ecasting results.
