Polyphenols have been shown in both in vitro and in vivo experiments to induce responses that are consistentwith the protective effects of diets rich in fruits and vegetables against degenerative conditions such ascardiovascular disorders and cancer. Red palm oil, extracted from the fruit mesocarp of Elaeis guineensis is veryimportant in the diet of many Nigerians, and indeed many citizens of developing countries living around thetropics. It contains antioxidant components such as carotenoids (alpha, beta, and gamma carotenes) and vitaminE (tocophorols and tocotrienols), which are of known nutritional and health benefits, but the antioxidantpolyphenol contents of this oil is not fully explored. To assess the total antioxidant potential due partly to thescavenging of reactive oxygen specie (ROS) and the inhibition of the enzyme, xanthine oxidase, thehypoxanthine/xanthine oxidase assay system and the 2-deoxyguanosine-assay model were utilized. Theserevealed that the oil possesses promising antioxidant and radical scavenging activities with IC50 values of 95 ?Mand 219 ?M for the hypoxanthine/xanthine oxidase and 2-deoxyguanosine assays, respectively.Liquid-Chromatography with Electrospray – Ionization Mass Spectrometry (LC-ESI) showed the presence of theantioxidant, 3,4 hydroxybenzyaldehyde, p-hydroxybenzoic acid, vanillic acid, syringic acid and ferulic acid inthe red palm oil. Thus, in addition to antioxidant compounds like carotenoids, and vitamin E, the red palm oilalso contains a rich mixture of phenolic compounds with potent antioxidant and radical scavenging capacitiesthat might also account significantly for its widely reported capacity to modulate stress-related disorders.
