“…Other flavonoid compounds without available standards were identified mainly by comparing molecular ions, product ions, and the elution orders of these compounds with those available in the published literature (Castillo-Muñoz et al, 2009;Liang et al, 2012b).…”

Vernaccia di San Gimignano is a Tuscan white wine, with a great historical tradition, produced mostly from the homonymous grapevine. One of the peculiarities of the vine, apart from producing fruity and sapid young wines, is the ability to generate structured wines, suitable for the aging process of “riserva” type. For a better understanding of the Vernaccia di San Gimignano characteristics, a research protocol has been set up. It specifically concerns the phenolic composition of the grapes observed by HPLC analysis. The hydroxycinnamic acids, the flavanols and the flavonols of the skins, the flavanols of the seeds and the hydroxycinnamic acids of the juice have been determined. The trans-caftaric acid is the predominant form in the juice (70-120 mg/L) and in the skins (5-12 mg/Kg) where there are higher values of quercetin (4-20 mg/Kg) and procyanidins (18-35 mg/Kg). Catechins (30-80 mg/Kg) prevail in the seeds.

“…The content of monomeric anthocyanins in wines decreased markedly during ripening in 2015, contrary to 2014. The anthocyanin synthesis and content of monomeric anthocyanins were affected by the temperatures, for example, in the cold year (2014), levels were significantly higher than in the hot and dry year (Liang et al, 2012). As indicated in Table 5, the contents of malvidin-3-O-glucoside were highest in MW-3.…”

Due to the special climate conditions in the Qingtongxia region, grapes are high in sugar and low in titratable acidity from the stages of ripening. Therefore, the common methods used for determining the maturity of grapes, which depend on the ratio of sugar and titratable acidity in other regions, are inappropriate in Qingtongxia. This research was done in order to seek for a simple and convenient method of determining the optimal harvest time of grapes, further providing some theoretical basis for improving the quality of wine in Qingtongxia. Phenolic contents and some basic physico-chemical parameters of Merlot and Pinot Noir were evaluated during different ripening stages. The results showed that a different harvest time significantly affects the phenolic contents and physico-chemical parameters of Merlot and Pinot Noir. The total contents of anthocyanins in skins and total contents of phenolic in seeds was screen out as two important indexes to evaluate the maturity of polyphenols, in order to better improve the quality of grape and wine.
