Enzymatic synthesis of [3'-O-methyl-(3)H]malvidin-3-glucoside from petunidin-3-glucoside.
Malvidin-3-glucoside has been labeled by enzymatic synthesis in a single-step experiment. Catechol-O-methyl transferase catalyzed the B-ring methylation of petunidin-3-glucoside, and S-Adenosyl-L-[methyl-(3)H] methionine was the methyl donor. Solid phase extraction and preparative high-performance liquid chromatography were necessary to separate [3'-O-methyl-(3)H]malvidin-3-glucoside from an is...
متن کاملAnti-inflammatory effect of the blueberry anthocyanins malvidin-3-glucoside and malvidin-3-galactoside in endothelial cells.
Blueberry fruits have a wide range of health benefits because of their abundant anthocyanins, which are natural antioxidants. The purpose of this study was to investigate the inhibitory effect of blueberry's two main anthocyanins (malvidin-3-glucoside and malvidin-3-galactoside) on inflammatory response in endothelial cells. These two malvidin glycosides could inhibit tumor necrosis factor-alph...
متن کاملLiquid Chromatographic Determination of Malvidin-3-O-Glucoside and Malvidin 3, 5-O-Diglucoside in Wine Samples by Direct Injection
A method for the determination of malvidin 3-O-glucoside (Oenin), and malvidin 3, 5-O-diglucoside (Malvin) in wines by on line HPLC coupled with UV, and fluorescence detectors is described. With the proposed method the samples were analysed by direct injection without a previous treatment. For method validation, satisfactory recoveries (> 95%) and suitable repeatabilities (within day: R.S.D. (n...
متن کاملGlyceraldehyde bridging between flavanols and malvidin-3-glucoside in model solutions.
Hydroxyl radicals (.OH) seem to have an important role in the oxidation of wine constituents and the production of important electrophilic aldehydes and ketones. In this experiment, glyceraldehyde, a .OH oxidation product of glycerol, recently described in wine, reacts with (+)-catechin, (-)-epicatechin, and malvidin-3-glucoside (Mv3gl), in model solutions, yielding new condensed phenolic compo...
