Potential Cancer-Chemopreventive Activities of Wine Stilbenoids and Flavans Extracted From Grape (Vitis vinifera) Cell Cultures

The Evolutionary Genomics of Grape (Vitis vinifera ssp. vinifera) Domestication

Evolutionary genomics of grape (Vitis vinifera ssp. vinifera) domestication

We gathered genomic data from grapes (Vitis vinifera ssp. vinifera), a clonally propagated perennial crop, to address three ongoing mysteries about plant domestication. The first is the duration of domestication; archaeological evidence suggests that domestication occurs over millennia, but genetic evidence indicates that it can occur rapidly. We estimated that our wild and cultivated grape sam...

Antimutagenic and DNA Damage Protective Activities of a Grape Extract from Vitis vinifera

Antimutagenic and DNA protective effect of an extract VinOserae from Vitis vinifera grapes on oxidative DNA damage was investigated. The extract’s ability to inhibit mutagenicity induced by tert-butyl hydroperoxide (t-BHP) and hydrogen peroxide (H2O2) was determined with Ames test using Salmonella typhimurium His− TA102 strain. Inhibition values of 44.2% and 67.0% were detected for t-BHP and H2...

Influence of vine vigor on grape (Vitis vinifera L. Cv. Pinot Noir) and wine proanthocyanidins.

The relationships between variations in grapevine (Vitis vinifera L. cv. Pinot noir) growth and resulting fruit and wine phenolic composition were investigated. The study was conducted in a commercial vineyard consisting of the same clone, rootstock, age, and vineyard management practices. The experimental design involved monitoring soil, vine growth, yield components, and fruit composition (so...

Adaptogenic and nootropic activities of aqueous extract of Vitis vinifera (grape seed)

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...
