Structure of a new dimeric acetaldehyde malvidin 3-glucoside condensation product
Tetrahedron Letters, 2002A new pigment was detected in wine-like model solution containing malvidin 3-O-glucoside and acetaldehyde. This compound was isolated, and its structure was investigated by UV, MS and NMR spectroscopies. The analytical data allowed identification of it to 8,8 methyl methine-linked malvidin 3-O-glucoside dimer.

Structural Characterization of New Malvidin 3-Glucoside−Catechin Aryl/Alkyl-Linked Pigments
Journal of Agricultural and Food Chemistry, 2004The condensation reaction between malvidin 3-glucoside and catechin mediated by isobutyraldehyde, benzaldehyde, and isovaleraldehyde was conducted in model solutions at two pH values (1.5 and 3.2). The formation of new alkyl/aryl-linked adducts corresponding to the structures malvidin 3-glucoside-isobutylcatechin, malvidin 3-glucoside-benzylcatechin ...

Malvidin 3-Glucoside–Fatty Acid Conjugates: From Hydrophilic toward Novel Lipophilic Derivatives
Journal of Agricultural and Food Chemistry, 2017This work describes the lipophilization reactions of malvidin 3-glucoside with different saturated fatty acid chain lengths using an enzymatic synthesis and the study of their physical-chemical and antioxidant properties. The lipophilic anthocyanins were obtained with satisfactory yields (22-40%) after column chromatography purifications, and they ...

An unusual acylated malvidin 3-glucoside from flowers of Impatiens textori Miq. (Balsaminaceae)
Phytochemistry, 2009 Acylated malvidin 3-glucoside was isolated from the purple flowers of Impatiens textori Miq. as a major anthocyanin component along with malvidin 3-(6''-malonyl-glucoside). Its structure was elucidated to be malvidin 3-O-[6-O-(3-hydroxy-3-methylglutaryl)-beta-glucopyranoside] by chemical and spectroscopic methods.

Synthesis of malvidin and petunidin in pigmented tissue cultures ofPetunia hybrida
Protoplasma, 1981In 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

Anthocyanone A: A Quinone Methide Derivative Resulting from Malvidin 3-O-Glucoside Degradation
Journal of Agricultural and Food Chemistry, 2007A new compound resulting from the oxidative degradation of maldivin 3-O-glucoside under acid conditions was detected in a wine model solution stored under 90 and 25 degrees C. It was isolated by semipreparative HPLC, and its structure was elucidated by UV-vis spectra, mass spectrometry (LC/MS), and NMR spectroscopy (1-D and 2-D).

Metabolic pathways of degradation of malvidin-3-O-monoglucoside by Candida oleophila
International Biodeterioration & Biodegradation, 2019Abstract This work proposes an initial approach to the biodegradation pathway of coloured monomeric compounds found in wine, specifically malvidin-3-O-monoglucoside (Mv3G) using a Candida oleophila isolate, and the identification of the resulting degradation products.
