Phenolic compound profiles in berry skins from nine red wine grape cultivars in northwest China.
Phenolic compound profiles were investigated by HPLC-MS in two consecutive years to assess genotypic variation in berry skins of nine red Vitis vinifera cultivars. The results showed that the types and levels of phenolic compounds greatly varied with cultivar. Common wine grape cultivars such as Syrah, Cabernet Sauvignon, Cabernet Gernischt and Merlot contained more types of anthocyanins, flavo...
متن کاملTissue-Specific Expression Analysis of Anthocyanin Biosynthetic Genes in White- and Red-Fleshed Grape Cultivars.
Yan73, a teinturier (dyer) grape variety in China, is one of the few Vitis vinifera cultivars with red-coloured berry flesh. To examine the tissue-specific expression of genes associated with berry colour in Yan73, we analysed the differential accumulation of anthocyanins in the skin and flesh tissues of two red-skinned grape varieties with either red (Yan73) or white flesh (Muscat Hamburg) bas...
متن کاملCharacterization of Phenolic Profile and Antioxidant Potential of Some Algerian Olive Oils Cultivars
Background: Olive oil is a source of antioxidants and poses positive effects on human health. The objective of this study was firstly to identify and quantify the phenolics of some Algerian olive oils; secondly, the antioxidant activity of the samples was assessed. Methods: The virgin olive oils used in this study were derived from three Algerian cultivars, including Azeradj, Bouchouk, and Che...

Guo D.-L., Zhang Q., Zhang G.-H. (2013): Characterization of grape cultivars from China using microsatellite markers. Czech J. Genet. Plant Breed., 49: 164–170. A total of 32 different grape cultivars including representatives of local Chinese cultivars, some important and widely grown Chinese cultivars and international reference cultivars were genotyped at nine microsatellite loci in order to...
متن کاملIsolation of flavanol-anthocyanin adducts by countercurrent chromatography.
Pigments of the flavanol-anthocyanin (F-A+) type detected earlier in wine are synthesized using a protocol adapted from the synthesis of procyanidin dimers. The F-A+ adduct thus obtained is purified by countercurrent liquid-liquid partition, currently referred to as countercurrent chromatography (CCC). The solvent system consists of tert-butyl methyl ether-n-butanol-acetonitrile-water (2:2:1:5,...
