Comparison of phenolic and chromatic characteristics of dry red wines made from native Chinese grape species and vitis vinifera

The phenolic and chromatic characteristics of dry red wines made from native Chinese species (Vitis amurensis and its hybrids, and V. davidii) and V. vinifera were evaluated by high-performance liquid chromatography/triple-quadrupole tandem mass spectrometry and spectrophotometer, respectively. V. amurensis and its hybrids wines had higher phenolic percentage of non-coumaroylated 3, 5-O-diglucosidic anthocyanins, V. davidii wines had higher phenolic percentage of coumaroylated 3, 5-O-diglucosidic anthocyanins, kaempferol-3-O-glucoside, and quercetin-3-O-rhamnoside, V. vinifera wines had higher phenolic percentage offlavan-3-ols and 3-O-monoglucosidic anthocyanins. Wines of native Chinese species had relatively higher blue % value and lower red % value. By the use of principal component analysis and Pearson correlation analysis, specific phenolic compounds could be recognized as phenolic fingerprints of different wines, which not only play an important role in wine differentiation, but also explain their chromatic differences.
