Abstract
In this research, the optimum extracting solvent of proanthocyanidins from grape seed was selected in methanol, ethanol, acetone, water. The results showed acetone is the optimum extracting solvent. Then, through single factor test, on the base of orthogonal test, the optimum extracting conditions were determined. The results were as the following: temperature 60 ℃, concentration of acetone 50%, extraction time 60 min, rate of solution to solid 6:1.
