| Abstract: | Extraction of total flavonoids from grape residues by ethanol reflux method was discussed. The quantity of total flavonoids extracted was determined. Optimum extraction conditions determined by orthogonal method were solvent 80% ethanol, duration 105 min, temperature 65 ℃, ratio of material to solvent of 1 ： 50, and operation 2 times and the content of total flavonoids was up to 54.42 mg/g. |
