Grapevines exhibit a wide spectrum of resistance to the powdery mildew fungus (PM), Erysiphe necator (Schw.) Burr., but little is known about the transcriptional basis of the defense to PM. Our microscopic observations showed that PM produced less hyphal growth and induced more brown-colored epidermal cells on leaves of PM-resistant Vitis aestivalis 'Norton' than on leaves of PM-susceptible Vit...

Vitis vinifera L.is a traditional Asian herb widely used for different health problems. In thepresent research, the ethanolic and the aqueous extracts of Vitis vinifera L. leaves collected fromshrub, grown in Tunisia, were prepared and evaluated for the antileishmanial activity againstLeishmani ainfantum promastigotes. The inhibitory concentration 50 (IC50) was determined andthe results showed ...

Reports have shown the antioxidant, hypotensive, hypolipidemic and vasodilatory effects of grape (Vitis vinifera L.) seed extract. We have recently shown the relaxatory effect of grape leaf extract on rat uterus and reduction of frog heart rate and contractility. The aim of the present study was to investigate the relaxant effect of Vitis vinifera leaf hydroalcoholic extract (VLHE) on rat thora...

The aerial parts of Vitis vinifera Linn. (Common grape, Hindi ⎯ Angur) have been widely used in Ayurveda to treat a variety of common and stress related disorders. The seed extract of grapes was evaluated by Sreemantula and others for antistress activity in normal and stress induced rats. Furthermore, the extract was studied for nootropic activity in rats and in vitro antioxidant potential to c...

Among the food plants, the presence of melatonin in grapes (Vitis vinifera L.) deserves particular attention because of the production of wine, an alcoholic beverage of economic relevance and with putative healthy effects. Furthermore, melatonin isomers have been detected in wine too. Recently, one of these isomers has been identified as tryptophan-ethylester, a compound with the same molecular...
