文摘
Polyphenols from the ethyl acetate extracts of red wine were successfully fractionated using a four-step process (solvent extraction, ion-exchange column chromatography, centrifugal partitionchromatography, and semipreparative HPLC), which resulted in the isolation of 22 compoundsbelonging to different classes of polyphenols (stilbenes, cinnamic acids, flavonoids). Five of themare red wine constituents reported for the first time. The newly isolated compounds includeresveratrol dimers, dihydroflavonols, and a cinnamic derivative.Keywords: Red wine; stilbenes; dihydroflavonols; centrifugal partition chromatography
