Carotenoids are essential dietary components utilized not only in pigmentation but also as immuno-stimulants and antioxidants. Reduced availability can have consequences on individual health and survival, thus making carotenoids a good indicator of e

A new chemical named parrodienes has been extracted from parrots' plumage. From the chemical point of view, parrodienes are polyunsaturated aldehydes similar to carotenoids. On the basis of this similarity we organized some biological experiments to

The antioxidant activity of a novel series of derivatives with a carotenoid-like structure was studied. These derivatives have recently been isolated chemically as a result of studies on the pigments present in a particular species of birds, namely p

GC/ms is an important method to determine drugs in biological fluids. For each of the most commonly used drugs a methanolic solution (100 micrograms/ml) was prepared; 30 microliters of each solution was evaporated using nitrogen flow and than diluted

Research has been carried out with the purpose of verifying whether the resveratrol content in the skins or pomace of grapes stored for a long period of time without any particular protection with regard to temperature and humidity, could lead to a r
