Native carotenoids composition of some tropical fruits

Many tropical fruits can be considered a reservoir of bioactive substances with a special interest due to their possible health-promoting properties. The interest in carotenoids from a nutritional standpoint has recently greatly increased, because of their important health benefits. Here we report the native carotenoids composition in six tropical fruits from Panama, which is considered a region of great biodiversity. The native carotenoid composition was directly investigated by an HPLC- DAD-APCI-MS methodology, for the first time. In Corozo 32 different carotenoids were detected, including a high content of -carotene and lycopene. Sastra showed the highest content of zeaxanthin among the fruit investigated. In Sapote 22 different carotenoids were detected, including -carotene and 10 different zeaxanthin-di-esters. Frutita showed a very high content of the apo-carotenoid -citraurin, and of a number of its esters. In Maracuyà chino 14 carotenoids were detected, including a high amounts of mono-esterified lauric acid with -cryptoxanthin and with cryptocapsin. Mamey rojo was characterized by ketocarotenoids with  rings, both hydroxylated and not hydroxylated.
