Stability of Anthocyanins from Red Grape Skins under Pressurized Liquid Extraction and Ultrasound-Assisted Extraction Conditions

open access: yesMolecules, 2014
The stability of anthocyanins from grape skins after applying different extraction techniques has been determined. The following compounds, previously extracted from real samples, were assessed: delphinidin 3-glucoside, cyanidin 3-glucoside, petunidin 3 ...

Theoretical Study of D-π-A Structured Malvidin for DSSC Application

open access: yesAsian Journal of Chemistry, 2023
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.

Non-Thermal Ultrasonic Extraction of Polyphenolic Compounds from Red Wine Lees

open access: yesFoods, 2020
This study presents the results of conventional aqueous (CE) and non-conventional ultrasound-assisted (UAE) extractions of polyphenolic compounds from lees extracts of red wine varieties (Merlot and Vranac). The effect of ultrasound extraction time (t, s)

Effect of ellagitannins, ellagic acid and volatile compounds from oak wood on the (+)-catechin, procyanidin B1 and malvidin-3-glucoside content of model wines [PDF]

open access: yes, 2008
Background and Aims: During ageing in oak barrels, wine undergoes changes because of the release of polyphenols and other molecules from wood. The aim of this study was to evaluate the influence of some oak wood-derived volatile compounds, ellagic acid

Malvidin and its Glycosides from Improve Endothelial Function by Anti-inflammatory and Angiotensin I-Converting Enzyme Inhibitory Effects

open access: yesNatural Product Communications, 2018
Protective effects of malvidin and the glycosides from Vaccinium ashei on endothelial cells were investigated. The results showed that malvidin, malvidin-3-glucoside, malvidin-3-galactoside, and their mixture could defend endothelial cells from damage ...

Comparison of the anthocyanins composition of five wine-making grape cultivars cultivated in the Wujiaqu area of Xinjiang, China

open access: yesOENO One, 2019
Anthocyanins biosynthesis are essentially determined by grape cultivar genotype. However, specific environmental and vine management conditions could alter the accumulation of anthocyanins.

Antiamnesic Potential of Malvidin on Aluminum Chloride Activated by the Free Radical Scavenging Property

open access: yesACS Omega, 2022
Objectives: Malvidin, a dietary anthocyanin can be a potent drug for the treatment of neuronal toxicity. The investigation was aimed to study the antioxidant role of malvidin against aluminum chloride (AlCl3)-induced neurotoxicity in rats. Methods: To evaluate the neuroprotective role of malvidin, the rats were divided into four different groups: group
