The present study was aimed to evaluate the malvidin's protective effects on damage induced by 30 min bilateral common carotid artery occlusion (BCCAO) and 60 min reperfusion (RE) in rat pial microcirculation. Rat pial microcirculation was observed using fluorescence microscopy through a closed cranial window. Western blotting analysis was performed to investigate the endothelial nitric oxide s...

An efficient process for the purification of anthocyanin monomeric isomers from wild blueberries of Lake Saint-Jean region (Quebec, Canada) was developed and easy scalable at industrial purpose. The blueberries were soaked in acidified ethanol, filtered, and the filtrate was cleaned by solid phase extraction using silica gel C-18 and DSC-SCX cation-exchange resin. Anthocyanin-enriched elutes (8...

In our previous work, we have identified, in a model wine solution containing malvidin 3-glucoside, epicatechin and acetaldehyde, a new condensation product--hydroxylethyl-malvidin-3-glucoside-ethyl-epicatechin. The objective of this work was to verify the presence of such new condensation products in red wine. For this purpose, red wine was fractionated into various fractions by column chromat...

Anthocyanins are flavonoid-derived compounds that can reduce blood pressure. This study aims to determine the affinity value of compound bind Angiotensin Converting Enzyme (ACE) and II type 1 Receptor (AT1R) distance shape bond occurs. The results anthocyanin-derived Delphinidin, Petunidin, Malvidin, Cyanidin, Peonidin, Pelargonidin have anti-hypertensive potential through Renin Aldosterone (RA...

The anthocyanins of Siahe Sardasht variety (Vitis vinifera L. var. S.S.) were extracted from freezed samples and were purified by adsorption on cation-exchange resin column. Individual pigments were separated by TLC on cellulose plates. Monomeric anthocyanin content that was determined by pH-differential, was 1740.11±3.58 mgL?1 (based on malvidin 3-glucose). Five major pigments were identified ...

Double pruning extended the harvest season of wine grape (Vitis vinifera L.) to dry winter, enabling production high quality wines in southeastern Brazil. Winter allows grapes fulfill not only technological maturation, but also phenolic ripeness. from Syrah harvested eight vineyards Brazil during three harvests were analyzed for their chemical and aromatic composition after bottling ageing 20, ...

The phenolic composition of wine is mostly determined by the accumulation compounds in grapes, as well their extraction into wine. To increase concentration yield reduction usually performed pruning, while to wines, maceration on skins extended for longer periods time. present study focuses possibilities apply both strategies improve polyphenol organic red wines Romanian variety ‘Fetească neagr...

Background: Spine grape has gained attention in the field of wine science due to its good growth characteristics. Spine grape wine has been made by local residents for a long time. However, the scientific evaluation of spine wine has not been systemically documented compared to Vitis vinifera grape wines Methods: We compared 11 spine wines from south China (W1-W11) with 7 high-quality internati...
