strawberry (fragaria ananassa duch.) is a good source of natural antioxidants. fruits from eight strawberry (fragaria ananassa duch.) cultivars (‘kurdistan’, ‘merck’, ‘camarosa’, ‘paros’, ‘queen elisa’, ‘ventana’, ‘selva’ and ‘pajaro’) were harvested at ripen stage and analyzed for total phenolic content, total anthocyanin content, vitamin c, total soluble solid and total antioxidant activity. ...

natural citrus biotypes are a valuable genetic resource in the country. investigation about diversity of biochemical compounds due to optimize the utilization and development of new varieties is useful. therefore, for identifying them, the fruits of 16 biotypes with numbers of 6, 8, 15, 21, 24, 25, 26, 29, 30, 41, 43, 45, 48, 51, 52 and 53 in the germplasm collection of the iran citrus research...

an experiment was conducted to determine of the effects of vitamin e and c supplementation in diet based on different source of oils on performance and serum parameters of broilers. a total of 320 broiler chicks (strain ross 308) used in a 2×2×2 factorial arrangement in the form of completely randomized design with eight treatments, four replicates and 10 chicks in each replicate. experimental ...

this study was designed to elucidate the effect of ascorbic acid on salivary total antioxidant capacity in smokers. in this single blind crossover clinical trial, the whole unstimulated saliva of 30 smokers, who were randomly divided into two groups, was collected. in the first phase after the saliva collection, one group of patients took 500 mg of vitamin c powder, for 3 weeks. then, saliva of...

  Purpose: The aim of this study was to investigate the effect of four weeks supplementation of   vitamin C on serum levels of total antioxidant capacity and malondialdehyde among inactive   men after an eccentric exercise.   Materials and Methods: Twenty non-athletic healthy volunteer men (24 ± 1.6 years old,   22.59 ± 2.62 body fat percentage and 48.96 ± 3.58 mL/kg/min maximum oxygen uptake) ...

introduction: the pathogenesis of diabetic disorders are unknown and may be multifactorial. one of the most important mechanisms of complications is glycosilation of proteins such as haemoglobin. structurally, vitamin c is similar to glucose and can act as glucose in many chemical reactions, therefore it may prevent non- enzymatic glycosilation of proteins such as haemoglobin and lipoproteins. ...

the aim of this study was to investigate the effects of administering antioxidants, including vitamin c and chitosan on oxidative stress markers in muscle as edible tissues of cyprinus carpio exposed to cadmium chloride. in this experiment, by exposing to 0.2 mg/l cadmium chloride for 21 days, fish were fed a normal diet, diet containing chitosan (1000 mg/kg diet), vitamin c (1000 mg/kg diet) o...

in this research the effect of conventional and ohmic pasteurization and storage time at different temperatures on some bioactive components of aloe vera gel juice was investigated. aloe vera gel juice was pasteurized conventionally and ohmically at 90 ºc for 1 min. the effect of pasteurization on vitamin c, total phenolic content  and juice color was evaluated. the samples pasteurized conventi...

abstract          background and objective: vitamins c and e are  the two main antioxidants involved in prevention of type 2 diabetes, by reducing oxidative stress. the aim of this study was to evaluate the effects of vitamins c and e supplementation independently, on serum levels of insulin, high sensitivity c-reactive protein (hs-crp) and resistin in people with type 2 diabetes.         metho...

  Purpose: Ascorbic acid has protective effects against coronary heart disease. These effects are   attributed to its antioxidant properties and its relation to plasma lipids. This study investigated the   effects of supplementing one gram of vitamin C per day on the serum serum lipoproteins of   healthy 18 to 55 years old individuals in Iran.   Materials and Methods: This study was conducted o...
