Abstract

Several classes of pigments are responsible for coloration in birds. Melanin pigments most commonly appear in bird feathers and bare parts. They impart black, brown and chestnut hues. carotenoids are a second Group of coloring biochemicals in birds. These two groups of pigment-based coloration are found in nearly every order of extant birds. In contrast, parrots Harbor brighy.colored pigments in their feathers, which have different structures. As many colored substances exhibit free-radical scavenging activity and parrots have quite a long lifespan, the aim of our study was to identify the structures of these substances, attempt their synthesis and study theur performance and possible use in cosmetics while overcoming stability problems. Studies were also planned to compare their efficacy with that of known anti.ageging molecules. We were able to identify a structural mojety that could be the bases for a new family of molecoles with high funcionality. This example could open up the field of research for new functional molecules derived from animal or vegetal metabolism, which so far have been neglected because of their high instability.
