Ultraviolet Fluorescence of Cyanidin and Malvidin Glycosides in Aqueous Environment

Spectroscopy Letters, 2007
Abstract The fluorescence of cyanidin 3‐glucoside (Cy 3‐glc), cyanidin 3,5‐diglucoside (Cy 3,5‐diglc) and malvidin 3,5‐diglucoside (Mv 3,5‐diglc) in binary solvents (water–methanol, 1∶1, v/v) and in water at pH 4–5.5 has been studied. The absorption spectra, steady‐state fluorescence spectra, and fluorescence excitation spectra have been measured ...

Interactions between catechin and malvidin-3-monoglucoside in model solutions

Zeitschrift f�r Lebensmittel-Untersuchung und -Forschung, 1995
The interaction between (+)-catechin and malvidin-3-monoglucoside was studied in model solutions at pH values of 3.2 and 4 over a 30-day period at 32 °C. With time, a progressive browning, accompanied by a hypso-chromic shift in their visible absorption maxima, was observed in the solutions.

Kinetics of Malvidin‐3‐Glucoside Condensation in Wine Model Systems

Journal of Food Science, 1983
ABSTRACT Wine model systems containing equimolar quantities of malvidin‐3‐glucoside and d‐catechin, with and without acetaldehyde, were stored anaerobically at 22, 32, 42, and 52°C. Malvidin‐3‐glucoside and d‐catechin disappearance and polymer appearance were monitored by HPLC and colorimetric methods.

Synthesis of malvidin and petunidin in pigmented tissue cultures ofPetunia hybrida

Protoplasma, 1981
In petunia cells culturedin vitro anthocyanin synthesis is usually repressed resulting in white/ yellow cells. However, we observed that in petunia strain AK-5000 purple cells appeared at a frequency of about 5 × 10−5. Analysis of the pigments showed that these cells contained the same anthocyanidins (petunidin and malvidin) as found in corollas of the

Kinetics of Thermal Degradation of the Anthocyanins Delphinidin‐3‐rutinoside and Malvidin‐3‐glucoside

Food / Nahrung, 1974
AbstractThe kinetics of the thermal degradation of the two anthocyanins delphinidin‐3‐rutinoside and malvidin‐3‐glucoside at 78, 88, 98 and 108 °C, depending on the pH and the type of solvent has been investigated. The first order reaction of delphinidin‐3‐rutinoside and malvidin‐3‐glucoside degradation has been established.

Effect of malvidin-3-monoglucoside on the browning of monomeric and dimeric flavanols

Zeitschrift f�r Lebensmitteluntersuchung und -Forschung A, 1998
The behaviour of (+)-catechin (cat), (–)-epicatechin (epi) and the procyanidin dimers B2 [epi-(4→8)-epi] and B3 [cat-(4→8)-cat], alone and in the presence of malvidin-3-monoglucoside, was studied in hydro-alcoholic solutions at pH 3.2 maintained at 32 °C for 120 days.

Malvidin-3-O-glucoside and Malvidin-3,5-O-diglucoside Alleviate Glycolipid Metabolic Disorder by Modulating Pancreas and Liver Functions and Gut Microbiota

Journal of Agricultural and Food Chemistry
The anthocyanins malvidin-3-O-glucoside (M3G) and malvidin-3,5-O-diglucoside (M35G) were purified from the grape varieties Vitis vinifera L. and Vitis davidii Foex peels, respectively, and their effects on glycolipid metabolic disorders (GLMDs) were investigated using a mouse model.
