Electrochemical oxidation of iodide has been studied in the presence of 2-thioborbituric acid using cyclic voltammetry and controlled-potential coulometry. The results indicate that, the resulting iodine takes part in halogenations reaction with 2-thiobarbituric acid. In addition, the present data are indicative of the suitability of iodide as a quasi mediator for determination of 2-thiobar...

The parent barbituric acid and 2-thiobarbituric acid are convenient starting compounds for the preparation of different fused heterocycles and 5-substituted derivatives which are pharmacologically one of the most important classes of barbituric acid based compounds. The fused compounds of barbituric and thiobarbituric acid 7-(4-aminophenyl)-5-aryl5H-pyrano [2, 3-d] pyrimidinone, 5a-f have been ...

The radical-scavenging activities of two thiols, eight (thio)barbituric acid derivatives and six chain-breaking phenolic antioxidants were investigated using the induction period method for polymerization of methyl methacrylate (MMA) initiated by thermal decomposition of 2,2’-azobisisobutyronitrile (AIBN) and monitored by differential scanning calorimetry (DSC). The induction period (IP) for th...

meat products, especially fish meat, are very susceptible to lipid oxidation and microbial spoilage. in this study, first, gas chromatography mass spectrometry (gc-ms) analysis of zataria multiflora essential oil (zeo) components was done and then two concentrations of zeo, (1% and 2%) and two concentrations of grape seed extract (gse), (0.5% and 1%) were used in carboxymethyl cellulose coating...

this study was carried out to evaluate how various amounts of nanozeolite decrease the effects of aflatoxins (af) on color and oxidative stability of the broiler thigh meat. three hundred and thirty six one-day-old ross 308 male broiler chickens were divided into six groups including a control group, which received diet without af and nanozeolite, and five treatment groups that received diet wi...

Three experiments were conducted to develop a sensitive and reliable fluorometric thiobarbituric acid (TBA) reactive substances (TBARS) method to determine lipid oxidation products in meat. The first study was conducted to find the optimum sample preparation conditions for meat in the fluorometric method. The second study was to compare the original and the modified methods by using meat and bl...
