Abstract
Polyphenols were extracted by ethanol solvent from blueberry marc.The results of single factor experiment on extraction conditions were designed by Design-Expert 7.0 software and optimized by experiments of Plackett-Burman and response surface methodology.The best extraction conditions were confirmed as follow:ethanol concentration was 60%,solvent/material ratio was 20(mL/g),extraction temperature was 80℃,pH was 2.Under these conditions,the percent of extracted polyphenols was 97.01%.
