Characterisation of Mediterranean grape pomace seed and skin extracts: polyphenolic content and antioxidant activity.
Grape pomace seeds and skins from different Mediterranean varieties (Grenache [GRE], Syrah [SYR], Carignan [CAR], Mourvèdre [MOU] and Alicante [ALI]) were extracted using water and water/ethanol 70% in order to develop edible extracts (an aqueous extract [EAQ] and a 70% hydro-alcoholic extract [EA70]) for potential use in nutraceutical or cosmetic formulations. In this study, global content (to...
متن کاملPolyphenolic Contents and Antioxidant Properties of Different Grape (V. vinifera, V. labrusca, and V. hybrid) Cultivars
The polyphenolic contents and the antioxidant activity of the skins and pulps of different grape cultivars were estimated using HPLC and DPPH antioxidant assay, respectively. The phenolics and flavonoids identified were quercetin, kaempferol, caffeic acid, p-coumaric acid, cinnamic acid, and (-)-epicatechin. The total phenolic contents were found to be the highest in the grape skin of Flouxa (>...
متن کاملBiological activities of Vitis vinifera L. leaves
The fractions of different polarity, namely chloroform, ethylacetate, n-butanol, and remaining water fractions, were fractionated from an aqueous extract of V. vinifera leaves. The antibacterial, antifungal, antiviral, antioxidant activities, and total phenolic content of these fractions were investigated. The chloroform fraction showed a promising effect against Herpes simplex virus type-1 (HS...

ABSTARCT Grape (Vitis vinifera) seed extract found to be exhibits wide range of beneficial effects insights to screen the potential compounds which includes polyphenolic compounds both flavonoids and non-flavonoids that show antioxidant effects. In this present study phytochemical screening of alkaloids, flavonoids, glycosides, polyphenol and flavonoids, tannins, and sterols were presented in t...
متن کاملGenetic structure and differentiation in cultivated grape, Vitis vinifera L.
222 cultivated (Vitis vinifera) and 22 wild (V. vinifera ssp. sylvestris) grape accessions were analysed for genetic diversity and differentiation at eight microsatellite loci. A total of 94 alleles were detected, with extensive polymorphism among the accessions. Multivariate relationships among accessions revealed 16 genetic groups structured into three clusters, supporting the classical eco-g...
