“…The most abundant flavonols were, in most cases, the 3-O-glucosides of myricetin (MyGl) and quercetin (QuGl), and the 3-O-glucuronide of quercetin (QuGr); in most cases, their content was higher than 20 mg/kg grapes, and sometimes exceeded 50 mg/kg grapes. These results are similar to those obtained previously in red grape cultivars [6,7]. Among the other flavonols, their content was usually low, less than 10 mg/kg grapes; the most remarkable exception was wild genotype H-6.1, which presented a remarkable content of QuGal.…”

“…Tables 2 and 3 summarize the quantitative data obtained after the examination of chromatograms obtained for the extracts of berry skins of 16 genotypes of wild grapes, and those obtained for reference grape cultivars (Pinot noir and Tempranillo). Total content of flavonols, taking into account the content of the four flavonols that have not been fully identified, ranged from 26.9 mg/kg grapes (genotype CA-6.1) to 349.7 mg/kg grapes (genotype H-6.1); these results are similar to those reported previously by other authors in red grape cultivars [6,7]. The most abundant flavonols were, in most cases, the 3-O-glucosides of myricetin (MyGl) and quercetin (QuGl), and the 3-O-glucuronide of quercetin (QuGr); in most cases, their content was higher than 20 mg/kg grapes, and sometimes exceeded 50 mg/kg grapes.…”

“…All these flavonols have identified in berries of several red grapevine cultivars [6,7], and their presence in wild grapes should be expected, as wild grapes are red colored. The flavonols tentatively identified were 3-O-galactosides of myricetin (MyGal) and quercetin (QuGal), which have been previously detected in red grape skins [7]. th World Congress of Vine and Wine Table 1.…”

Flavonols in skins of wild grapes (Vitis viniferaL., subsp. sylvestris (Gmelin) Hegi)

Abstract. Flavonols are a group of grape phenolics that play an important role in young red wines, as they are involved in copigmentation of the flavylium form of anthocyanins. A study on the flavonol composition of grape skins in several wild grapevine genotypes from different Iberian natural populations, preserved at El Encin Germoplasm Bank, has been carried out in 2012. Flavonol glycosides contained in grape skins were determined by HPLC-DAD and HPLC-MS, through a previous phase of purification, using ion exchange chromatographic columns to retain anthocyanins and other phenolic compounds, so that flavonols do not suffer co-elution with other components, improving HPLC analysis. Thus, it was possible to separate 12 flavonol glycosides, and eight of them were successfully identified. The major flavonols were quercetin-3-O-glucoside, quercetin-3-O-glucoronide and myricetin-3-O-glucoside. The diversity and number of flavonols differed for each genotype. The total content of flavonols ranged from 25 to 350 mg/kg grapes; the richest genotype was three times richer than Tempranillo grapes, used as a reference. The most significant difference between wild genotypes and reference cultivars was that, in many cases, myricetin-3-O-glucoside or quercetin-3-Oglucuronide predominated in wild genotypes.

“…The genome of each grapevine variety predetermines its typical profi le of anthocyanins, by which individual grapevine cultivars can be diff erentiated (6)(7)(8)(9)(10)(11)(12) and thus the anthocyanin profi le can be used to identify the grape variety used for making varietal wines (13). Consequently, it can also be used for the authentication of red wines, especially in the cases when the grapevine variety is displayed on the label (14).…”

SummaryIn recent years, the importance of wine authenticity specifi cation has signifi cantly infl uenced the world wine market. Nowadays, the importance of terroir is emphasised worldwide. Also in European countries, where varietal wines are produced predominantly, the wine authenticity is given an increasing a ention. Anthocyanin pigments represent an important group of phenolic substances that are used for the evaluation of wine authenticity. In this study, altogether 17 varietal red wines originating from the village Dolní Kounice (wine-growing region Moravia, Czech Republic) are evaluated. The evaluation involved three varieties, viz. Blaufränkisch (Lemberger), Saint Laurent and Blauer Portugieser as well as three terroirs named Karlov, Šibeniční vrch and Na Nivách. Anthocyanin pigments in varietal red wines were estimated by means of the HPLC method. Thanks to the application of chemometric methods, it was possible to determine the grapevine variety and to classify red wines on the basis of delphinidin-3-O-glucoside (DpGl), malvidin-3-O-glucoside (MvGl) and delphinidin-3-O-acetylglucoside (DpGlAc) content. The terroir was discriminated on the basis of DpGl, MvGl and delphinidin-3-O-p-coumarylglucoside (DpGlCm) content.

Analysis of the phenolic composition of fungus‐resistant grape varieties cultivated in Italy and Germany using UHPLC‐MS/MS

The phenolic composition of grape berries grown in Italy (Cabernet Cortis, Johanniter, Solaris, Phoenix, and Regent) and in Germany (Regent and Phoenix) was analyzed using two complementary LC-MS/MS (Liquid Chromatography - Tandem Quadrupole Mass Spectrometry) methods. These five cultivars belong to fungus-resistant grape varieties (PIWI) and little is known about their phenolic profile, although phenolics such as phytoalexins have been recognized, playing a key role in the resistance mechanism. A triple quadruple mass spectrometer detector was used for both identification and quantification, and analytical tools from untargeted metabolomics were applied to check and control the quality of the results. Specifically, biological, technical, and instrumental replications were included in order to study the variability at different levels. The results allowed tuning of the sampling protocol and provided a rich phenolic metabolite profile for the aforementioned PIWI varieties, as compared with Vitis vinifera cultivars, especially in the class of stilbenes.
