Abstract

Abstract Astilbin (dihydroquercetin 3-rhamnoside) and engeletin (dihydrokaempferol 3-rhamnoside) were isolated for the first time from grapes. Details of their identification include nonderivatized 1H NMR spectra. These flavanonol glycosides were concentrated in the skins of white grapes, and were also present in white wines as shown by HPLC. Amounts and relative amounts differed by cultivar. They may be involved in certain discoloration problems during wine processing.
