Anthocyanin content is a trait of major interest in Vitis vinifera L. These compounds affect grape and wine quality, and have beneficial effects on human health. A candidate-gene approach was used to identify genetic variants associated with anthocyanin content in grape berries. A total of 445 polymorphisms were identified in 5 genes encoding transcription factors and 10 genes involved in eithe...

Plants growing in high-light environments during winter often exhibit leaf reddening due to synthesis of anthocyanin pigments, which are thought to alleviate photooxidative stress associated with low-temperature photoinhibition through light attenuation and/or antioxidant activity. Seasonal high-light stress can be further exacerbated by a limited photosynthetic capacity, such as nitrogen-defic...

Anthocyanins are responsible for the color of grapes and wine, an important attribute of their quality. Many authors have used anthocyanins profile to classify the grape cultivars and wine authenticity. The anthocyanin profiles of grape berries of Vitis amurensis, its hybrids and their wines were analyzed by HPLC-ESI-MS/MS. The results identified 17 anthocyanins in these grape cultivars, includ...

The anthocyanin and chlorophyll contents in leaves provide valuable information about the physiological status of plants. Thus, there is a need for accurate, efficient, and practical methodologies to estimate these biochemical parameters of vegetation. In this study, we tested the performance and accuracy of several nondestructive, reflectance-based techniques for estimating anthocyanin and chl...

A dynamic human gastrointestinal (GI) model was used to digest cooked tubers from purple-fleshed Amachi and Leona potato cultivars to study anthocyanin biotransformation in the stomach, small intestine and colonic vessels. Colonic Caco-2 cancer cells and non-tumorigenic colonic CCD-112CoN cells were tested for cytotoxicity and cell viability after 24 h exposure to colonic fecal water (FW) diges...

Background: Cornus sanguinea L subsp australis (C.A. Mey.) Jáv. (Cornaceae) is a native species in north and northwest of Iran. It is locally named Siah-al. The genus Cornus is rich source of anthocyanins. Objective: In this study the antioxidant activity, total phenol and total anthocyanin contents of different extracts of C. sanguinea L subsp australis. were investigated for the first time. ...

E-mail addresses: [email protected] Lingonberries and their products are popular and generally accessible in Europe, though in the US they are uncommon and considered a minor berry/fruit crop. The on-going interest in potential health benefits from berry ...

Background and Objectives: Black mulberry is a juicy and dark purple to black fruit with a good balance of sweetness and tartness. This fruit is highly interested due to high quantities of anthocyanins. The bioactive compounds are often present in fruit tissues and should be released. The aim of this study was to extract bioactive compounds of black mulberries and assessment of heating process ...

grapes are significant sources of nutritional antioxidants as well as biologically active dietary components. this study was carried out to determine the amount of total phenols, anthocyanins and antioxidant activity of 35 grapevine (vitis vinifera l.) cultivars grown in fars province (iran). ripened bunches were randomly harvested from grapevine collection in zarghan (fars province, iran) agri...

rashe grape cultivar grows in kurdistan province in rain fed conditions. microclimate conditions have a great effect on grape berry quality. information about changes in grape berry composition in the relation to climate changes is limited. in order to measure the effects of slope and altitude on some grape berry chemical composition, a study was conducted on grape cv. ‘rasheh’ in university of...
