Abstract
Carotenoids have multiple functions in photosynthetic systems. A part of them have been well documented /1,2/. More recently, an additional function has been proposed which involves a specific carotenoid-chlorophyll interaction in their singlet excited states, leading to a quenching in chlorophyll (Chl) fluorescence. This means that carotenoids may play a role in regulating the energy flow of Chl excited states in photosynthetic antenna, being implied in an energy dissipation route. The former reports concerning the quenching of Chl fluorescence by β-carotene have been shown to be contradictory /3–5/. Further studies have shown that β-carotene can quench Chi a fluorescence in organic solvents /6,7/.
