Variability in chemical composition of Vitis vinifera cv Mencía from different geographic areas and vintages in Ribeira Sacra (NW Spain)

Anthocyanin composition of grapes from three different soil types in cv. Tempranillo A.O.C. Rioja vineyards

“…Ribera de Duero (Spain), the highest total anthocyanin and extractable anthocyanin concentrations during the wet as opposed to the dry seasons throughout the period 2004–2013. In their work, Vilanova et al observed in 15 vineyards of Mencía significant differences in grape anthocyanin composition among the vintages 2009–2012 in four of the Ribeira Sacra A.O.C. (Galicia, NW Spain) geographic areas studied.…”

Grapes and Atherosclerosis

“…2 Grape polyphenols have been shown to have anti-oxidative, anti-inflammatory, and vasodilation properties using animal models and cell studies. For the anti-oxidative properties, they have been shown to decrease LDL oxidation (Castilla et al 2006;Vilanova et al 2015) and oxidative stress (Fuhrman et al 2005), reduce reactive oxygen species (ROS) (Ramprasath and Jones 2010;Vinson 2001), and reduce cyclooxygenase (COX) activity (Fan et al 2008). The antiinflammatory properties that have been reported are decreased NF-κB binding to DNA (Sankatsing et al 2005;Fan et al 2008), decreases in leukocyte adhesion (Suh et al 2011), reduction in tissue factor (TF) expression (Décordé et al 2008), reduction in platelet aggregation (Seymour et al 2010), and reduced metalloproteinase-2 (MM2) (Lekakis et al 2005;Cui et al 2012).…”

“…Other studies have evaluated the effects of resveratrol, a stilbene present in grapes (Vilanova et al 2015), mainly in the skin of these fruits (Bertelli and Das 2009). Resveratrol has been recognized as having pleiotropic effects on chronic disease including cancer, diabetes, and atherosclerosis (Ramprasath and Jones 2010).…”

The stilbene profile in edible berries

“…Many analytical methods with various detection techniques are reported for the separation and identification of individual stilbenes in edible berries, such as liquid chromatography-tandem mass spectrometry (LC-MS/MS) (Vrhovsek et al 2012), liquid chromatography-mass spectrometry (LC-MS) (Može et al 2011), liquid chromatography with dual detection by a photodiode array and quadrupole time-of-flight mass spectrometry (LC-PDA-QTOF/MS) (Samoticha et al 2017), high-pressure liquid chromatography-mass spectrometry (HPLC-MS) (Bavaresco et al 2002;Jiang et al 2012;Kiselev et al 2017), high-pressure liquid chromatography with diode array detection (HPLC-DAD) (Bavaresco et al 2002;Sun et al 2006;Vilanova et al 2015;Guerrero et al 2010aGuerrero et al , 2016, high-pressure liquid chromatography with UV detection (HPLC-UV) (Vincenzi et al 2013;Kawakami et al 2014;He et al 2009a), ultra-high-pressure liquid chromatography quadrupole time-of-flight mass spectrometry (UHPLC/QTOF/MS) (Flamini et al 2016;De Rosso et al 2016), ultra-performance liquid chromatography with dual detection by a photodiode array and fluorescence detectors (UPLC/DAD/FL) (Samoticha et al 2017), ultra-performance liquid chromatography with dual detection by a diode array and tandem quadrupole mass spectrometry (UPLC/ DAD/TQD) (Guerrero et al 2010a), gas chromatography-mass spectrometry (GC-MS) (Ragab et al 2006;Viñas et al 2009Viñas et al , 2011, gas chromatographymass spectrometry with selected ion monitoring (GC-MS SIM) (Rimando and Cody 2005), gas-liquid chromatography with flame ionization detection (GLC-FID) (Moriartry et al 2001), capillary electrophoresis (CE) (Ehala et al 2005) and high-speed counter-current chromatography (HSCC) (He et al 2009b). Various methods are used for analyses of stilbenes contents in the edible berries are different which could also contribute to the observed variability in the published results.…”
