Cyanidin 3-malonylglucuronylglucoside in Bellis and cyanidin 3-malonylglucoside in Dendranthema

Phytochemistry, 1988
Abstract -The major anthocyanin of three red cultivars of Dendranthema morifolium has been identified as cyanidin 3- O -(6- O -malonyl-β- d -glucopyranoside) by FABMS and NMR spectroscopy. The major anthocyanin of red flowers of Bellis perennis has been identified as cyanidin 3- O -(6- O -matonyl-4- O -(β- d -glucuronyl)-β- d -glucopyranoside ...

Products of Thermal Degradation of the Anthocyanins Cyanidin‐3‐glucoside, Cyanidin‐3‐rutinoside and Cyanidin‐3‐sophoroside

Food / Nahrung, 1976
AbstractDuring thermal degradation of anthocyanins, cyanidin‐3‐glucoside, cyanidin‐3‐rutinoside, cyanidin‐3‐sophoroside, at 98 °C in model systems of pH = 1, 2.5 3.5 and 4.5, seven compounds were isolated by means of paper chromatography. Among them quercetin, phloroglucin‐aldehyde and protocatechuic acid were identified.

Urinary excretion of cyanidin glycosides

Journal of Biochemical and Biophysical Methods, 2002
Anthocyanins, which are natural plant pigments from the flavonoid family, represent substantial constituents of the human diet. Several fruits (blackcurrant, blue berries, red grape and elderberry) are rich sources of these efficient antioxidant compounds.

Cyanidin and cyanidin 3-O-β-D-glucoside as DNA cleavage protectors and antioxidants

Cell Biology and Toxicology, 2003
Anthocyanins, colored flavonoids, are water-soluble pigments present in the plant kingdom; in fact they are secondary plant metabolites responsible for the blue, purple, and red color of many plant tissues. Present in beans, fruits, vegetables and red wines, considerable amounts of anthocyanins are ingested as constituents of the human diet (180-215 mg

Detection of Cyanidin in Different-colored Peanut Testae and Identification of Peanut Cyanidin 3-sambubioside

Journal of Agricultural and Food Chemistry, 2009
Peanut testae are potent sources of polyphenols. When the water extracts and acid hydrolysates of five different-colored testae were analyzed by HPLC, chromatograms monitored at 280 nm varied remarkably, whereas two major peaks in the chromatograms monitored at 530 nm were detected only in kernels having completely or partially black color.

Antioxidative Activity of the Anthocyanin Pigments Cyanidin 3-O-.beta.-D-Glucoside and Cyanidin

Journal of Agricultural and Food Chemistry, 1994
The antioxidative activity of the anthocyanin pigments cyanidin 3-O-β-D-glucoside (C3G) and cyanidin (Cy) was examined by using linoleic acid autoxidation, liposome, rabbit erythrocyte membrane, and rat liver microsomal systems. C3G and Cy had antioxidative activity in all systems.

Influence of cyanidin glycosylation patterns on carboxypyranoanthocyanin formation

Food Chemistry, 2018
Anthocyanins can condense with compounds having enolizable groups to form pyranoanthocyanins. These pigments are less susceptible to degradation and color changes associated with nucleophilic addition common to anthocyanins. This study aimed to evaluate the impact of glycosylation patterns of anthocyanins on carboxypyranoanthocyanin formation.

DFT investigation of the reaction of cyanidin with hydroxyl radical

2015 IEEE 15th International Conference on Bioinformatics and Bioengineering (BIBE), 2015
Cyanidin, as one important plant pigment, was theoretically (at M05-2X/6-311+G(d, p) level of theory) investigated for its ability to scavenge potentially, highly damaging hydroxyl radical. The applied method successfully reproduces the bond dissociation enthalpy (BDE), the ionization potential (IP) and proton affinity (PA).

‘Leuco-cyanidin’ and Epicatechin

Nature, 1953
Bate-Smith and Swain1 have recently come to the conclusion that the so-called condensed, ‘catechin’, tannins are in many instances identical with the ‘leuco-anthocyanins’ described by Robinson and Robinson2. Recent work here has suggested that the catechins and ‘leuco-anthocyanins’ are extremely closely related.

Adsorption of Flavonoids on Resins:  Cyanidin 3-Glucoside

Journal of Agricultural and Food Chemistry, 2004
Adsorption of cyanidin-3-glucoside in aqueous batch solutions was studied at pH 3.5 and 20 degrees C using 13 commercial resins with different hydrophobicity, surface areas (SA, 330-1200 m2/g), and pore radii (PR, 20-260 A). The solute affinity toward different resins was described in terms of Langmuir and Freundlich parameters; experimental data were ...
