Glyceraldehyde Bridging between Flavanols and Malvidin-3-glucoside in Model Solutions [PDF]

open access: yesJournal of Agricultural and Food Chemistry, 2006
Hydroxyl radicals (.OH) seem to have an important role in the oxidation of wine constituents and the production of important electrophilic aldehydes and ketones. In this experiment, glyceraldehyde, a .OH oxidation product of glycerol, recently described in wine, reacts with (+)-catechin, (-)-epicatechin, and malvidin-3-glucoside (Mv3gl), in model ...

Malvidin Protects against and Repairs Peptic Ulcers in Mice by Alleviating Oxidative Stress and Inflammation [PDF]

open access: yes, 2021
Peptic ulcer episodes cause damage to the stomach and intestine, with inflammatory cell infiltration and oxidative stress as the main players. In this study, we investigated the potential of anthocyanidin malvidin for preventive and curative peptic ulcer

Effects of monoglucoside and diglucoside anthocyanins from Yan 73 (Vitis vinifera L.) and spine grape (Vitis davidii Foex) skin on intestinal microbiota in vitro

open access: yesFood Chemistry: X, 2022
Yan 73 anthocyanin extracts and spine grape anthocyanin extracts, along with anthocyanin standards (malvidin-3-O-glucoside; malvidin-3,5-O-diglucoside), were used to investigate the role of anthocyanins and their structures (monoglucoside, diglucoside ...

Influence of Different Phenolic Copigments on the Color of Malvidin 3-Glucoside [PDF]

open access: yesJournal of Agricultural and Food Chemistry, 2006
The effectiveness of seven phenolic compounds (catechin, epicatechin, procyanidin B2, caffeic acid, p-coumaric acid, myricitrin, and quercitrin) as copigments of malvidin 3-glucoside, the major anthocyanin in red wines from Vitis vinifera, using a copigment/pigment molar ratio of 1:1 was assayed in model wine solutions under the same conditions (pH=3.6,

Effect of Lachancea thermotolerans on the Formation of Polymeric Pigments during Sequential Fermentation with Schizosaccharosmyces pombe and Saccharomyces cerevisiae

open access: yesMolecules, 2018
Anthocyanins in red grape musts may evolve during the winemaking process and wine aging for several different reasons; colour stability and evolution is a complex process that may depend on grape variety, winemaking technology, fermentative yeast ...

Effect of Vintage and Viticultural Practices on the Phenolic Content of Hybrid Winegrapes in Very Cool Climate

open access: yesAgriculture, 2020
Vine growing and wine production is gaining in popularity around the Baltic Sea Region. The first aim of the experiment was to determine the variability of the total phenolic and anthocyanin content (from 2010 to 2018) and of individual anthocyanin ...

Inhibition of Enzymes by the Anthocyanin Malvidin-3-Monoglucoside.

open access: yesExperimental Biology and Medicine, 1967
SummaryThe cytoplasmic, particulate, and cell wall fractions were isolated from disrupted bacterial cells and assayed for MADH, GDH, HX, and GLD enzymes in absence of pigment (control) and presence of various M-3-G concentrations. The magnitude of enzymatic inhibition due to increasing concentrations of M-3-G (1 to 4 μM) was not the same for each ...

Anthocyanins—Nature’s Bold, Beautiful, and Health-Promoting Colors

open access: yesFoods, 2019
Anthocyanins are among the most interesting and vigorously studied plant compounds, representing a large class of over 700 polyphenolic pigments within the flavonoid family that exist ubiquitously in the human diet. They are “nature’s colors,&

Hypoglycemic and hypolipidemic effects of blueberry anthocyanins by AMPK activation: In vitro and in vivo studies

open access: yesRedox Biology, 2021
Blueberries are rich in bioactive anthocyanins, with a high level of malvidin, which is associated with antioxidant benefits that contribute to reducing the risk of diabetes.

Colour and antioxidant properties of malvidin-3-glucoside and Vitisin A [PDF]

open access: yesActa Alimentaria, 2016
This study presents findings from comparing the properties of anthocyanin pigments: i. malvidin-3-glucoside (Mal-3-G), the most significant anthocyanin present in young red wine; ii. Vitisin A (5-carboxypyranomalvidin-3-glucoside), a major product from a reaction induced in red wine between Mal-3-G and pyruvic acid during its ageing.
