“…The anthocyanin profile under this study was mainly formed by the related monoglucosides and acylated with either acetic, or p-coumaric from the five anthocyanidin structures (Lingua et al, 2016). As can be seen in Table 4, malvidin derivatives presented the highest concentration among all anthocyanins detected in grapes and wines, being malvidin-3-O-glucoside the main anthocyanins, which was consistent with many authors (Portu et al, 2016;Lingua et al, 2016). This is because malvidin is the terminal anthocyanidin in biosynthesis of anthocyanins (Núñez et al, 2004).…”

A comprehensive investigation was conducted to determine the effects of exogenous melatonin treatment of pre-veraison grapes on phenolic components and antioxidants of grape berries and wine. The results showed an increase in the concentration of cyanin-3-O-glucoside, peonidin derivatives, and two flavanols [namely (+)-catechins and (−)-epicatechins] of grapes, as well as flavonols in both grapes and wine due to the application of melatonin. These compounds are derivatives of the catalysate of flavonoid 3'-hydroxylase (F3'H) in the flavonoid synthesis pathway of plants. Ot can be inferred that melatonin increased the activity of F3'H or expression of VvF3'H during grape berry maturation. On addition, two melatonin treatments of pre-veraison grape berries reduced the DPPH radical-scavenging ability and copper ion-reducing power of grapes and wine, whereas one melatonin treatment just reduced those in wine. This study will provide a practical strategy to change the phenolic composition of grapes and wine.Keywords: melatonin; grape; wine; phenolics; antioxidant activity.Practical Application: This study will facilitate the production of quality wine using melatonin.

“…Therefore, it is possible that colder climates provide a slow ripening of grapes allowing a synthesis of flavanols and HCAs in grapes. trans-Piceid found in 'Carignan' grapes is higher than to those exposed by some authors (López-Hernández and Rodríguez-Bernaldo de Quirós, 2016;Portu et al, 2016), mainly in the grapes collected from Peu site. It has been showed that the concentration of stilbenes increased after plant diseases (Chong et al, 2009).…”

Among the forgotten varieties within the Chilean wine industry, 'Carignan' grapevines (Vitis vinifera L.) in the Maule Valley, Chile, have been rediscovered by viticulturist and winemakers, producing very interesting wines and well recognized worldwide. Phenolic compounds are secondary metabolites, and there has been much interest in potential health benefits of polyphenols as antioxidants. The aim of this work was to study grape phenolic composition from 'Carignan' vineyards growing in eight different sites of the Maule Valley during the 2016 vintage. Phenolic compounds were analyzed by HPLC-DAD. The results showed that, as expected, the most abundant anthocyanin, flavonol, flavanol and hydroxycinnamic acid in 'Carignan' grapes were malvidin-3-glc varying from 279.56 to 428.68 mg kg -1 , quercetin-3-glucoside+rutin ranging from 27.64 to 82.69 mg kg -1 , procyanidin B1 varying from 39.13 to 72.84 mg kg -1 and trans-coutaric acid varying from 27.14 to 72.76 mg kg -1 , respectively. transPiceid was the only stilbene identified, which ranged from 1.06 to 7.67 mg kg -1 . Climate conditions more than soil characteristics affected grape ripening. Generally, grapes from Curtiduría (Cur) and El Peumal (Peu) presented a faster ripening, in terms of technological maturity, than grapes harvested from the rest of the sites, regarding day of season. In most of the phenolic compounds, grapes from Peu, presented higher concentration than grapes from the rest of the sites. Thus, location conditioned phenolic composition in grapes. These findings are of importance for the Chilean wine industry in relation to the viticultural management of the 'Carignan' variety, regarding climatic conditions, soil characteristics and ripening within the Maule Valley.

“…Chitosan and yeast extracts have been applied to grapevines as elicitors, with the aim of improving the synthesis of phenolic amino acids and volatile compounds in grape berries, and subsequently in the wines. Foliar treatments of methyl jasmonate and yeast extracts applied to Tempranillo grapevines improved the grape and wine anthocyanin concentrations . In addition, yeast extracts improved the stilbene concentrations in the grapes .…”

Foliar application of biostimulants (including resistance inducers or elicitors) in the vineyard has become an interesting strategy to prevent plant diseases and improve grape quality on the grapevine. This also represents a partial alternative to soil fertilisation, avoiding some of the negative effects to the environment from leaching of nutrients into the groundwater. The foliar applications that most promote the synthesis of secondary metabolites in grape berries are treatments with nitrogen, elicitors, other biostimulants, and waste from the agricultural industry. However, the impact of their use in the vineyard depends on a number of conditions, including mainly the type of compound, application rate, timing and number of applications, and cultivar. This review thus summarises the influence of biostimulants as foliar applications to grapevines on grape amino acids and their phenolic and volatile concentrations, to define the most important factors in their effectiveness. © 2018 Society of Chemical Industry.
