Introduction: Exposure to ionizing radiation can trigger adverse biological effects on healthy tissues, such as causing hematological toxicity and potential injury to different organs. Ionizing radiation has sufficient energy to liberate electrons from atoms leaving them with unpaired electrons; hence ionizing them and producing free radicals. In the current study, the...

Modern medicinal agents currently available for treatment of cancers are very expensive, toxic, and less effective in treating some of the disease. Thus, one must investigate further in detail the agents derived from natural sources, such as grape seed, for the prevention and treatment of cancer and disease. In recent years interest of researchers has focused on grape seed and nowadays scientis...

carbon (c) and organic nitrogen (n) mineralization processes play key roles in supplying nutrient elements essential for plant growth. on the other hand, since the low organic matter content of agricultural soils of arid and semi-arid areas, microbial activities are often limited by carbon in these types of soils. enhancement of microbial activities and populations could be achieved by returnin...

BACKGROUND The objective of the present study was to determine the phytochemical content and the protective effect of red grape skin extract (RGSE) against fructose-mediated protein oxidation. In addition, RGSE was screened for its potential as an antioxidant using various in vitro models. METHODS Antioxidant activity was measured by 2,2-diphenyl-1-picrylhydrazyl (DPPH), hydroxyl radical scav...

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 (>...

Pectin is a polysaccharide with wider applications in foods, pharmaceuticals, and several of other industries. The extraction determination vitamins from pectin obtained citrus fruit peels were studied. was extracted using ethanol. It observed that orange gave the highest yield (28.31±2.85%) followed by red grape (14.72±1.83%), lime (12.10±0.97%), least (10.15±0.61%).The level vitamin A (mg/g) ...

Am. J. Enol. Vitic. 56:3 (2005) 197 Phenolic compounds are important to red wine quality because they impact color, mouthfeel, and ageability. Although phenolics are present in grape juice, the amount is greatly increased in wine because of their greater solubility in ethanol than in purely aqueous solutions. Typical levels of the major grape phenolics present in red wine are shown in Table 1. ...
