ZusammenfassungNach neueren Ergebnissen kann das Vorkommen vontrans-Resveratrol (trans-3,5,4′-Trihydroxystilben) in Rotweinen eine therapeutische Bedeutung haben. Eine wichtige Voraussetzung ist deshalb eine möglichst schnelle und zuverlässige Bestimmungsmethode. Für die Anreicherung und Vortrennung dieser Komponente aus Wein wurde eine Fest-Phasen-Extraktion mit C18-Umkehr-Kartuschen ausgearbeitet. Die anschließende HPLC-Analyse unter Anwendung der internen Standard-Auswertemethode und einem… Expand
High performance liquid chromatography-diode array detector (HPLC-DAD) detection of trans-resveratrol: Evolution during ripening in grape berry skins
Trans-resveratrol (3, 5, 4' – trihydroxy-trans-stilbene) is a stilbene naturally present in a number of plant families. Berry skins of grape (Vitis vinifera L.), Alicante, Black Malvasia, Nerello andExpand
Occurrence of a resveratrol ß-D-glucoside in wine : Preliminary sturlies
Introduction: Much interest had been focused upon resveratrol (trans-3,5,4'-trihydroxystilbene, Fig. 1), a phytoalexin present in some grape species whose synthesis is induced upon fungal infectionExpand
Gas chromatography and high‐pressure liquid chromatography determination of resveratrol in Italian red wines
Resveratrol (trans‐3,5,4'‐trihydroxystilbene) is a phenolic compound naturally produced by different plants, including grapes. Its presence is quite common in red wines, while very much lowerExpand
Effect of Enological Practices on the Resveratrol Isomer Content of Wine
Resveratrol (trans-3,5,4'-trihydroxystilbene) is a phytoalexin produced by grapevines in response to fungal infection, particularly to Botrytis cinerea, the causal organism for gray mold. ThisExpand
Constitutive stilbene contents of grapevine cluster stems as potential source of resveratrol in wine
Ripe clusters of 8 Vitis vinifera L. varieties (Cabernet franc, Gewurztraminer, Marzemino, Merlot, Moscato, Pinot gris, Sauvignon, Tocai friulano) were analysed to determine the constitutional levelsExpand
Glucosylation of Smoke-Derived Volatiles in Grapevine (Vitis vinifera) is Catalyzed by a Promiscuous Resveratrol/Guaiacol Glucosyltransferase.
TLDR
To identify glycosyltransferases involved in the formation of glycosidically bound smoke-derived volatiles, gene expression analysis of candidate GTs in different grapevine tissues will help to design strategies for managing the risk of producing smoke-affected wines. Expand
Comparison of polyphenols and aroma in red wines from Portuguese mainland versus Azores Islands
Abstract trans-Resveratrol (trans-3,5,4′.trihydroxystilbene), piceid (resveratrol 3-O-β-D-glucopyranoside), together with their isomers and quercetin were measured in red wines from cultivars grownExpand
Comparative Analysis of Concentrations of trans-and cis-Resveratrol in Must and Wine from Eleven Different Grapevines Grown in Hokkaido, Northern Japan
It has been suggested that resveratrol (RT) has a protective effect against cardiovascular diseases. We analyzed the concentration of RT in must and wine samples made from nine varieties of red andExpand
Resveratrol: a molecule whose time has come? And gone?
TLDR
Up to the present, conclusive evidence for its absorption by human subjectsin biologically significant amounts is lacking, and it is questionable that its powerful and beneficial in vitro activities are reproduced as a consequence of sustained moderate red wine consumption. Expand
Benzothiadiazole enhances resveratrol and anthocyanin biosynthesis in grapevine, meanwhile improving resistance to Botrytis cinerea.
TLDR
Results indicate that BTH treatments, besides improving the content of two important classes of nutraceuticals, with their well-known antioxidant, antitumoral, and phytoestrogenic activities, could be exploited in vineyard to protect grape against gray mould infection, thereby limiting an excessive use of fungicides.

The Production of Resveratrol (3,5,4'-trihydroxystilbene) by Grape Berries in Different Developmental Stages
TLDR
The decrease of resveratrol production during maturation was confirmed by the fact that there is a clear negative correlation between the resver atrol content of grape skin and the developmental stage of berries measured by the sugar concentration of juice. Expand
Effects of stilbene components of roots of Polygonum ssp. on liver injury in peroxidized oil-fed rats.
TLDR
Resveratrol, piceid and 2,3,5,4′-tetrahydroxy stilbene-2-O-D-glucoside were found to inhibit lipid peroxidation induced by ADP and NADPH in rat liver microsomes. Expand

Abstract The effects of various stilbenes (i.e, 3,4',5-trihydroxystilbene, 3,4',5-trihydroxystilbene 3-O- d -glucoside and 2,3,4',5-tetrahydroxystilbene 2-O- d -glucoside ) isolated from the roots ofExpand
The chromatographic and spectral properties of stilbene derivatives.
TLDR
The RF of 26 stilbene aglycones and glucosides have been determined in several systems by means of paper Chromatography and thin-layer chromatography and interpretation of the spectral changes have been made in terms of the structure of stilbenes which also can be divided into several groups due to spectral changes with added sodium ethylate.

The significance of stilbene phytoalexins in the Plasmopara viticola-grapevine interaction
TLDR
Results suggest that reservatrol is more important for the regulation of the Plasmopara viticola -grapevine interaction than e-viniferin and that phytoalexin response of the host was dependent on inoculum density. Expand
Disease resistance of Vitis spp. and the production of the stress metabolites resveratrol, ε-viniferin, α-viniferin and pterostilbene
TLDR
Attempts to determine the times, local sites and concentration at which stress metabolites accumulate in relation to growth of the pathogen suggest that these stress metabolites are responsible for inhibiting Growth of the pathogens in resistant interactions. Expand

Abstract Trans -resveratrol (4,3′,5′-trihydroxy stilbene) has been identified as the major component responsible for the blue fluorescence of grapevine leaf tissue following fungal infection orExpand
Concentration of the Phytoalexin Resveratrol in Wine
Resveratrol is a phytoalexin found in grapes. Recent research had shown that orally administered resveratrol lowered lipid levels in the liver of rats. Wine had been shown to lower serum lipid levelsExpand
