Antioxidant and anti-inflammatory effects in RAW264.7 macrophages of malvidin, a major red wine polyphenol. [PDF]

PLoS ONE, 2013
Red wine polyphenols can prevent cardiovascular and inflammatory diseases. Resveratrol, the most extensively studied constituent, is unlikely to solely account for these beneficial effects because of its rather low abundance and bioavailability. Malvidin

Charge equilibria and pKa of malvidin-3-glucoside by electrophoresis

Analytical Biochemistry, 2003
Paper electrophoresis has been used over the pH range 1.2 to 10.4 to measure apparent pK(a) values for malvidin-3-O-glucoside of pK(a(1)) 1.76+/-0.07, pK(a(2)) 5.36+/-0.04, and pK(a(3)) 8.39+/-0.07. Using solvent partitioning between buffered aqueous solutions and n-octanol, several micro-pK(a) constants for malvidin-3-O-glucoside were also identified,

Influence of oenological tannins on malvidin-3-O-monoglucoside copigmentation in a model wine solution

OENO One, 2019
Aim: The aim of the study was to evaluate the effects of five different oenological tannins on the color of a malvidin-3-O-monoglucoside solution, and thereby assess the effectiveness of these tannins as copigments.

The Absence of Malvidin-3-Glucoside in Petiole Tissue Predicts Rare Red-Type Flower of Eastern Redbud (Cercis canadensis L.)

Agriculture, 2023
Eastern redbud, Cercis canadensis L., is a popular ornamental tree in the U.S. and has flower colors of purple-type, red-type, and white-type. Most redbuds cultivars have purple-type flowers. Red-types and white-types are much less common.

OsUGT88C3 Encodes a UDP-Glycosyltransferase Responsible for Biosynthesis of Malvidin 3-O-Galactoside in Rice

Plants
The diversity of anthocyanins is largely due to the action of glycosyltransferases, which add sugar moieties to anthocyanidins. Although a number of glycosyltransferases have been identified to glycosylate anthocyanidin in plants, the enzyme that ...

Optimization of the Enzymatic Acylation Reaction Conditions of Vitis davidii Malvidin

Shipin gongye ke-ji, 2022
In order to increase the structural stability of anthocyanins, taking Vitis davidii malvidin as sample and the lipase CAL-B as catalyst, the effects of reaction time, temperature, and substrate molar ratio on enzymatic acylation were investigated.

Malvidin-3-O-glucoside Chemical Behavior in the Wine pH Range

Journal of Agricultural and Food Chemistry, 2019
Anthocyanins are natural pigments responsible for the typical color of red wines and are critically associated with the wine commercial value and longevity. Thus, understanding the molecular bases of the anthocyanin chemical behavior in the complex wine environment is a central issue to the enological sector.
