Abstract
Extraction of total flavonoids from grape residues by supersonic method were discussed.The quantity of total flavonoids extracted was determined.Optimum conditions of extraction were determined by orthogonal method: the ratio of material over solvent is 1∶40 using 95% ethanol as solvent,and the extracting time is about 90min at the temperature of 60℃ by 2 times.The content of total flavonoids was up to 78.12mg/g.
