title: [Response surface analysis for optimization of comprehensive extraction of flavonoid and polysaccharide in fermented Ampelopsis grossedentata].
abstract: OBJECTIVE
  To explore the comprehensive extraction conditions of flavonoid and polysaccharide in fermented Ampelopsis grossedentata.
  
  
  METHODS
  On the basis of single factor experiments, response surface analysis (RSA) was used to optimize the extraction of flavonoid and polysaccharide in fermented Ampelopsis grossedentata.
  
  
  RESULTS
  The optimal conditions were as follows: temperature 96 degrees C, time 1.6 h, solid-liquid ratio 1:21. Under these conditions, the total flavonoids extraction yield was 22.94%, the polysaccharide extraction yield was 2.13%.
  
  
  CONCLUSIONS
  This study provides a reference for the comprehensive extraction of flavonoid and polysaccharide in fermented Ampelopsis grossedentata, and lays a foundation for the comprehensive development and utilization of Ampelopsis grossedentata.
