        High pressure liquid chromatographic techniques with fluorimetric detection for the evaluation of antioxidative parameters in vivo and structure-activity assessment of antioxidative natural products. 01/01/2001 - 31/12/2003

        Abstract

        This project covers the assessment of the in vivo antioxidative properties of natural products. In a first step, rats are stressed with CCl4, after which the concentration of free malondialdehyde and related hydroxyalkenals, determined by means of HPLC, of stressed laboratory animals is compared to the normal, basal concentration. The use of fluorimetric detection enhances both sensitivity and selectivity of the method substantially, important parameters when using small laboratory animals with low MDA plasma concentrations. Subsequently, the in vivo antioxidative effect of some selected polyphenols will be determined, with emphasis on flavonoids and proanthocyanidins. For those compounds structure-activity relationships for in vivo inhibition of lipid peroxidation will be investigated.
