  journal={Food Chemistry},
Six raisin grape cultivars and 10 new raisin grape selections were analyzed for antioxidant activity (ABTS assay) and for total and individual phenolic compounds. Samples were freeze–dried and values are reported on a dry weight basis. Antioxidant activity across the 16 samples ranged from 7.7 to 60.9 lmol Trolox/g DW, with A95-27 exhibiting the greatest activity. Total phenolic content, determined in gallic acid equivalents using the Folin–Ciocalteau assay, ranged from 316.3 to 1141.3 mg… Expand

Analysis of commercial grape raisins: phenolic content, antioxidant capacity and radical scavenger activity
Seven different commercial grape raisins from the Spanish market were evaluated for total phenolic composition, antioxidant potential and scavenger activity. Commercial red raisins (from the CardinalExpand
Comparison of phenolic profiles and antioxidant activities in skins and pulps of eleven grape cultivars (Vitis vinifera L.)
Abstract Eleven grape cultivars were analysed to explore the variety differences of fresh grape phenolic profiles. The results showed that free phenolics were predominant in grape skins and pulps,Expand
Changes in the phenolic profile of Argentinean fresh grapes during production of sun-dried raisins
Abstract Changes in the phenolic profile of ‘Arizul’, ‘Sultanina’, ‘Superior’, and ‘Flame’ grapes from the Province of San Juan (Argentina) caused by sun drying were evaluated. Our main goal was toExpand
Phytochemical Content, Antioxidant Properties, and Phenolic Profile of Tunisian Raisin Varieties (Vitis Vinifera L.)
Four raisin (Vitis vinifera L.) varieties, Chriha, Razeki, Assli, and Meski, were evaluated for total phenolic content, total o-diphenol content, total flavonoid content, total condensed tannin,Expand
Recovery of Bioactive Compounds from Unripe Red Grapes (cv. Sangiovese) through a Green Extraction
An efficient industrial-scale “green” extraction method was developed to obtain a safe extract with a high concentration of bioactive compounds and the antioxidant activity of the extract from unripe Sangiovese grapes was positively correlated with all the phenol compounds. Expand
Antioxidant activities of some dried fruits consumed in Algeria
Dried fruits such as prune, apricots, raisins and figs are an important source of different antioxidants which can inhibit the harmful effects of the free radicals. They receive increasing attentionExpand
Antioxidant capacity and phenolic profile of berry, seed, and skin of Ekşikara (vitis vinifera L) grape: Influence of harvest year and altitude
Ekşikara is a poorly known native Turkish grape cultivar, which is being cultivated for thousands of years for table consumption, raisin, and grape molasses production, and the effect of harvesting year and altitude of the vineyard location was investigated. Expand
SUMMARY Seven different commercial grape raisins from the Spanish market were evaluated for total phenolic composition, antioxidant potential and scavenger activity. Commercial red raisins (from theExpand
Comparative evaluation of the phenolic content and antioxidant capacity of sun-dried raisins.
Strong correlations between antioxidative capacity and phenolic content and between antioxidants and flavonol content were noticed and the total phenolic and anthocyanins content vary widely among different raisins. Expand
Determination of phenolic substances and antioxidant activities in some grape cultivars by HPLC.
While different values of phenolic substances were detected for different cultivars, the highest antioxidant activities were identified in Kis Kirmizisi, and Gallic acid was only detected in cv. Expand


Phenolic content and antioxidant capacity of muscadine grapes.
According to previous results, ellagic acid and not resveratrol was the major phenolic in muscadine grapes, but reported here for the first time are the phenolic content and antioxidant capacity of mus cadine leaves. Expand

Antioxidant properties and bioactive components of Norton (Vitis aestivalis) and Cabernet Franc (Vitis vinifera) wine grapes
Abstract Three wine grapes, Norton ( Vitis aestivalis ), Cabernet Franc clone1, and Cabernet Franc clone313 ( Vitis vinifera ), collected from a Virginia vineyard were evaluated and compared forExpand
Polyphenolic composition of raisins.
Golden raisins had the highest amount of hydroxycinnamic acids and the highest lightness values and formation of hydroxymethylfurfural and loss of amino acids in sun-dried and dipped raisin samples are ascribed to Maillard browning reactions. Expand
Polyphenol screening of pomace from red and white grape varieties (Vitis vinifera L.) by HPLC-DAD-MS/MS.
It is confirmed that both skins and seeds of most grape cultivars constitute a promising source of polyphenolics, and this is the first study presenting comprehensive data on the contents of individual phenolic compounds comprising all polyphenolic subclasses of grapes. Expand
Caftaric and coutaric acids in fruit of Vitis
The proportion of coutaric acid appeared quite variable (3-33 % of the caftaric content in the vinifera cultivars) by variety and was apparently genetically controlled. Expand
