eng	Native carotenoids composition in two Brasilian fruits from the Cerrado area	Many tropical and sub-tropical fruits have great health potential due to the possible presence of bioactive phytochemicals. The objective of this study was to report the native carotenoids composition in two fruits from Brasil, Pequi (Caryocar brasiliensis) and Ora Pro Nobis (Pereskia aculeata). Fully mature fruits were collected in the Cerrado area in Brasil and analyzed by HPLC/DAD/APCI-MS after carotenoids extraction with hexane and ethyl acetate. The mobile phase composed of methanol, methyl-terc-butyl ether and water. Separation was carried out on C30 column using gradient elution. The native carotenoids composition had never been previously reported for that two investigated fruits. However, compositional natural food databases are very important sources of information relative to natural food biodiversity and nutritional properties. In Pequi, the carotenoids composition was mainly constituted by the carotenoids monoesters of myristic and palmitic acids with -cryptoxanthin. The esterification provides greater stability to the carotenoids and enhances their bioavailability; moreover -cryptoxanthin is a well know precursor of vitamin A. In Ora Pro Nobis, the carotenoids composition was mainly constituted by the carotenoids monoesters of lauric acid with lutein and with zeaxanthin. Both lutein and zeaxanthin are important xanthophylls, with a well documented positive effect in the prevention of the age related macula degeneration.	carotenoids, LC/MS
