OBJECTIVE Grape virus diseases are a serious problem in Iran. Leaves and fruits of grape have been used for different purposes like cooking in Iran. The present investigation was carried out to study on the cytotoxic-activities of extracts of fruits and leaves of Vitis vinifera from both virus-free and virus-infected grape cultivars against breast cancer cell line (MDAMB- 231) and human embryon...

The genus Vitis (the grapevine) is a group of highly diverse, diploid woody perennial vines consisting of approximately 60 species from across the northern hemisphere. It is the world's most valuable horticultural crop with ~8 million hectares planted, most of which is processed into wine. To gain insights into the use of wild Vitis species during the past century of interspecific grape breedin...

Margarodes vitis es un hemíptero que causa daños severos en la productividad de los viñedos del valle central Chile. Existen escasas formas control esta plaga, debido principalmente a su hábito subterráneo, donde parasita raíces, comprometiendo viabilidad vid. El objetivo este estudio fue evaluar el efecto distintas concentraciones extracto ajo morado sobre mortalidad quistes M. vides variedad ...

Objective: Scientificstudies have shown that Vitis vinifera (V. vinifera) contains flavonoids and stillbenoids. Flavonoids are well known to possess anxiolytic activities. In view of the idea that flavonoids present in V. vinifera could be useful in anxiety, we evaluated anxiolytic-like activity of V. vinifera juice (VVJ). Materials and Methods: Light/dark box and the open field test were used ...

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 ...

different grapevine cultures that were inoculated with Plasmopara viticola as a host pathogen and Pseudoperonospora cubensis as a non-host pathogen. The results of the expression analysis showed that the PR1 mRNA level in Vitis vinifera cv. Riesling and Vitis riparia cv. Gloire de Montpellier is mainly affected by the culture system. PR1 is constitutively expressed in callus cultures. In vitro ...

Viticulture and wine production are indispensable elements of Europe’s cultural civilizational identity. The study aimed to characterize raw materials obtained from the common grape vine Vitis vinifera L., their use in cosmetology, presentation vinotherapy as an interesting, cosmetically useful approach utilize body care human well-being improvement. In Poland, treatments becoming a popular sup...

The necrotrophic fungus Botrytis cinerea is a major threat to grapevine cultivation worldwide. A screen of 41 Vitis genotypes for leaf resistance to B. cinerea suggested species independent variation and revealed 18 resistant Chinese wild Vitis genotypes, while most investigated V. vinifera, or its hybrids, were susceptible. A particularly resistant Chinese wild Vitis, "Pingli-5" (V. sp. [Qinli...

Anthocyanins in grapes. Red wine color is incredibly complex. Any given wine is composed of hundreds of dynamic chemicals that are interacting and changing during the winemaking process. While evolution of color from purple-red to brick red in Vitis vinifera wines is familiar to both winemaking and scientific communities, the color of hybrid wines is less predictable, and often varies from the ...

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...
