abstract: country’s fiber optic network, as one of the most important communication infrastructures, is of high importance; therefore, ensuring security of the network and its data is essential. no remarkable research has been done on assessing security of the country’s fiber optic network. besides, according to an official statistics released by ertebatat zirsakht company, unwanted disconnec...
Leafs have contain wide antioxidant range which may provide prevention against radical oxygen species. The aim of this work was to measure the antioxidant capacity of 15 commercially available leaf extracts (ethanol, methanol, water) using ferric reducing antioxidant power (FRAP) assay and trolox equivalent antioxidant capacity (TEAC) assay. Also we evaluated total phenolic and monomeric anthoc...
Reactive oxygen species (ROS) play a critical role in the impairment of nitric oxide mediated vascular functions and overall pathogenesis associated with cardiovascular disease. Plant pigment anthocyanins are exceptionally potent oxygen radical scavengers that produce beneficial effects in diseases outside the cardiovascular system. We examined for the first time the potential coronary vasoacti...
Functional compounds from black rice were extracted conventionally using organic solvents, namely ethanol-distilled water and water-acid (acetic acid a mixture of lactic acetic acid) along with distilled as control. The effectiveness each solvent was determined by analysis functional contents (anthocyanin content, flavonoids, total phenolic, antioxidant activity), pH value, the resulting color ...
The purpose of this study was to obtain the best anthocyanin pigment extract powder from 3 types of drying process, vacuum drying, spray drying, and freeze-drying. The duration and temperature for each type of drying process are 15 h with temperature of 40 oC, 2 h with temperature of 120 oC (inlet) and 60 oC (outlet), 24 h with temperature of -50 o</su...
The initial concentration of anthocyanin and proanthocyanidin in wine affects the development SO 2 -resistant pigments, as well color non-color contributing polymeric fractions. However, effect extracted monomeric Pinot Noir ( Vitis vinifera L. cv.) grape anthocyanins with seed proanthocyanidins are poorly studied. In model ferments, reaction purified cv. noir extract were investigated at high ...
Arabinoxylans are considered as the major limiting factor for use of rye in animal feeding. In this study, four selected winter rye cultivars were grown at nine locations and tested for arabinoxylans including total (TAX), soluble (SAX) and insoluble fractions (IAX), extract viscosity, falling numbers and crude protein contents. Amounts of TAX ranged on average between 89 and 103 g/kg wholemeal...
