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 کاملAntioxidant Activity, Antiproliferation of Colon Cancer Cells, and Chemical Composition of Grape Pomace
Chardonnay and Tinta Cao grape pomaces were generated by the winemaking process. The pomaces were extracted with 50% acetone and tested for antioxidant capacities using the oxygen radical absorbance capacity (ORAC) assay, 50 EC , and ABTS •+ scavenging capacity tests. Cytotoxicity and antiproliferative activities against Caco-2 and HT-29 human colon cancer cell lines were also analyzed. The qua...
متن کاملChanges of the Anthocyanins and Antioxidant properties of Concord Grape (Vitis labrusca) Pomace After Acid Hydrolysis
Grape pomace contains high levels of valuable antioxidants such as anthocyanins and phenolic compounds that help prevent chronic diseases such as cardiovascular problems and cancers. In this study, Concord grape pomace was soaked in acidic solutions at different time intervals and pHs in a water bath at 80 o C. Five kinds of anthocyanins were released and identified in the pomace after acid hyd...
متن کاملGrape pomace extract exerts antioxidant effects through an increase in GCS levels and GST activity in muscle and endothelial cells
In a previous study, we demonstrated that a grape pomace extract (GPE) exerted antioxidant activity in endothelial (EA.hy926) and muscle (C2C12) cells through an increase in glutathione (GSH) levels. In the present study, in order to elucidate the mechanisms responsible for the antioxidant activity of GPE, its effects on the expression of critical antioxidant enzymes, such as catalase (CAT), su...
