pH-induced structural forms of cyanidin and cyanidin 3-O-β-glucopyranoside

Dyes and Pigments, 2019
Abstract The structural forms of cyanidin and cyanidin 3-O-β-glucopyranoside (Cy3Glc) were investigated in the pH range from 0.4 to 13.5 for cyanidin and 0.4 to 13.2 for Cy3Glc. The 3-glucosidic substitution in cyanidin 3-O-β-glucopyranoside at pH values lower than 4.0 was manifested in a large hyperchromic effect, while at pH values higher than 4.0 ...

Cyanidin-3-O-Glucoside and Cyanidin Protect Against Intestinal Barrier Damage and 2,4,6-Trinitrobenzenesulfonic Acid-Induced Colitis.

Journal of Medicinal Food, 2020
Anthocyanin-rich extracts have shown anti-inflammation activity in mouse colitis models. Cyanidin-3-glucoside (C3G) is one of the widespread anthocyanins in plants, and cyanidin (Cy) is the aglycone of C3G that can be generated in intestine under gut ...

Cyanidin 3-Rutinoside and Cyanidin 3-Xylosylrutinoside as Primary Phenolic Antioxidants in Black Raspberry

Journal of Agricultural and Food Chemistry, 2008
Anthocyanin constituents in black raspberries (Rubus occidentalis L.) were investigated by HPLC-DAD, and their involvement as potent, significant antioxidants in black raspberries was demonstrated by three common antioxidant assays (FRAP, DPPH, ABTS) in this study. Five anthocyanins were present in black raspberries: cyanidin 3-sambubioside, cyanidin 3-

Anthocyanin profiling of maize grains using DIESI-MSQD reveals that cyanidin-based derivatives predominate in purple corn, whereas pelargonidin-based molecules occur in red-pink varieties from Mexico.

Journal of Agricultural and Food Chemistry, 2020
Corn seeds contain natural pigments and antioxidants, such as the molecular variants of flavonoids and carotenoids. The aleurone and pericarp tissue from pigmented genotypes were extracted for metabolic fingerprinting and evaluated using UV-VIS and mass ...

Interactions of cyanidin and cyanidin 3-O-β-glucopyranoside with model lipid membranes

Journal of Thermal Analysis and Calorimetry, 2016
Cyanidin and cyanidin 3-O-β-glucopyranoside (Cy3Glc) are flavonoids that have several biological properties, including as antioxidants. The interactions of cyanidin and Cy3Glc with model lipid membranes differing in surface charge and phase state were investigated using differential scanning calorimetry and fluorescence emission polarization ...

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.

Enhanced chemical stability, intestinal absorption, and intracellular antioxidant activity of cyanidin-3-O-glucoside by composite nanogel encapsulation.

Journal of Agricultural and Food Chemistry, 2019
A composite nanogel was developed for cyanidin-3-O-glucoside (C3G) delivery by combining Maillard reaction and heat-gelation. The starting materials utilized were ovalbumin, dextran, and pectin. C3G-loaded nanogel was spherical with a diameter of ~185 nm,

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.

Identification of cyanidin-3-arabinoside extracted from blueberry as selective PTP1B inhibitor.

Journal of Agricultural and Food Chemistry, 2019
Protein tyrosine phosphatase 1 B (PTP1B) is an important target for type 2 diabetes. PTP1B inhibitors can reduce blood glucose level by increasing insulin sensitivity.
