Graphical Abstract

Abstract

Abstract

Accelerated solvent extraction(ASE) system was used to optimize polyphenol extraction from seeds of a new grape cultivar “ Meili ” through orthogonal test. The results showed that the optimum extraction conditions were as follows : extraction time 30 min, temperature 50 ℃, pressure 8.97 MPa and ethanol concentration 80%. The yield of extraction was 28.89 mg/g. The ASE method could effectively reduce the operation time.
