Study on Separation and Purification of Resveratrol in Wine Grape Residue with Aqueous Two Phase Extraction Method

Abstract:

The separation and purification of resveratrol in wine grape residue with aqueous two phase extraction method were studied in this paper. Used identified ethanol - ammonium sulfate - water as the aqueous two-phase system, the wine grape residue extract substances separated well. By TLC and HPLC analysis, resveratrol content (13.3μg/ml) in aqueous two-phase extraction was higher than the results (2.342μg/ml) in organic solvent extraction. The results showed that the aqueous two phase extraction method could be used in primary separation and purification of resveratrol in wine grape residue.
