Abstract

An increased oxidative status is described after myocardial infarction. On the other hand, many beneficial effects have been attributed to constituents of plant foods, especially antioxidants. Rosemary is one of the most widely used herbs, known for its antioxidant effect. To support its use, it is of great relevance to characterize its compounds and its antioxidant actions. Objectives: identify phenolic compounds present in the rosemary extract used for supplementation in the main project and to determine the antioxidant status after rosemary supplementation in circulation as well as target tissue, cardiac tissue. Methods: rosemary extract produced in Brazil will be tested for antioxidant activity of fat and water soluble components and characterization of phenolic compounds using LC/UV/ESI-MS/MS analysis. Serum and heart tissue collected from animals used on the main project will be analyzed for protein carbonyl determination and total antioxidant performance. Values of the comparison between heart and serum analysis will be presented as mean ± SEM and comparisons will be made by two-way ANOVA test, with significance level of 5%. (AU)
