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

Several reports on the biological activity of anthocyanin-rich extracts have been made. However, despite the association of said activity with their anthocyanin content, to the best of our knowledge, there are no previous works regarding the antimicrobial, antibiofilm and/or antiadhesive properties of anthocyanins alone.

Physico-Chemical and Chromatic Characterization of Malvidin 3-Glucoside-vinylcatechol and Malvidin 3-Glucoside-vinylguaiacol Wine Pigments [PDF]
The physicochemical and chromatic features of malvidin 3-glucoside-vinylcatechol (PA1) and malvidin 3-glucoside-vinylguaiacol (PA2) adducts were investigated. Important differences between both pigments were observed. In the investigated pH range (2.0-4.5), our results suggest that PA1 could be considered as a noncovalent dimer of two pyranoflavylium ...

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

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

Effect of Blueberry Anthocyanins Malvidin and Glycosides on the Antioxidant Properties in Endothelial Cells [PDF]
The objective of this research was to survey the antioxidant functional role of the main anthocyanins of blueberries in endothelial cells. Changes on the reactive oxygen species (ROS), xanthine oxidase‐1 (XO‐1), superoxide dismutase (SOD), and heme oxygenase‐1 (HO‐1) in cells of malvidin and the two glycosides were investigated. The results showed that

The Effect of the Storage on the Content of the Malvidin-3-Glucoside in Red Wine [PDF]
Abstract Anthocyanins are plant dyes responsible for the colour of red wine. Of these, malvidin-3-glucoside is the most significant member and its content was monitored in wines that were first left to age in oak barrels for 12 months, subsequently bottled and sealed with plastic/cork stoppers.

Theoretical Study of D-π-A Structured Malvidin for DSSC Application
Six novel dye molecules were developed from D-π-A system and their suitability for dye sensitized solar cells (DSSCs) was evaluated using density functional theory (DFT). All the calculation were performed using B3LYP/6-311++ G (d,p) level basis set. The intermolecular charge transfer was examined using Frontier molecular orbitals.

Chemical characterization of an encapsulated red wine powder and its effects on neuronal cells [PDF]
Red wine polyphenols are known for their implications for human health protection, although they suffer from high instability. For this reason, a red wine powder was prepared by freeze-drying encapsulation in maltodextrin/arabic gum matrix, and its ...
