title: [Comparative study of extraction of corn stigma polysaccharide].
abstract: OBJECTIVE
  To study enzyme treatment, transonic and a combination of the two processes for the extraction of corn stigma polysaccharide.
  
  
  METHODS
  Enzyme and ultrasound-assisted extraction conditions were optimized respectively through orthogonal test. A combination of the two methods was investigated.
  
  
  RESULTS
  The combined method was more efficient than the enzyme treatment and transonic individually. The enzyme-assisted process was in the medium level in compare of the other two.
  
  
  CONCLUSIONS
  The combined method was the most favourable one.
