|Title:||Carotenoids and Phenolic Compounds from Solanum sessiliflorum, an Unexploited Amazonian Fruit, and Their Scavenging Capacities against Reactive Oxygen and Nitrogen Species|
|Abstract:||The composition of carotenoids and phenolic compounds from mana-cubiu (Solanum sessiliflorum), a fruit native to Amazonia, was determined by high-performance liquid chromatography coupled to diode array and mass spectrometry detectors (HPLC-DAD-MS'). The antioxidant capacities of the hydrophilic and carotenoid extracts against some reactive oxygen (ROO center dot, H2O2, HOCl, and HO center dot) and nitrogen (ONOO-) species were also determined. Seventeen carotenoids and three phenolic compounds were found in mana-cubiu. The major carotenoids were (all-E)-beta-carotene (7.15 mu g/g of dry weight) and (all-E)-lutein (2.41 mu g/g of dry weight). The 5-caffeoylquinic acid (1351 mu g/g of dry weight) was the major phenolic compound, representing more than 78% (w/w) of the total phenolic compounds. Moreover, two dihydrocaffeoyl spermidines were found in the hydrophilic extract. Both mana-cubiu extracts were able to scavenge all the tested reactive species. The carotenoid extract was shown to be a potent scavenger of peroxyl radical, while the hydrophilic extract was a potent hydrogen peroxide and hypochlorous acid scavenger.|
