文摘
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鈥揇AD鈥揗Sn). The antioxidant capacities of the hydrophilic and carotenoid extracts against some reactive oxygen (ROO鈥?/sup>, H2O2, HOCl, and HO鈥?/sup>) and nitrogen (ONOO鈥?/sup>) species were also determined. Seventeen carotenoids and three phenolic compounds were found in mana-cubiu. The major carotenoids were (all-E)-尾-carotene (7.15 渭g/g of dry weight) and (all-E)-lutein (2.41 渭g/g of dry weight). The 5-caffeoylquinic acid (1351 渭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.
