Abstract
- The edible fruits of 12 plants were extracted in methanol and subjected to solvent–solvent partitioning to yield three fractions, hexane, ethyl acetate, and aqueous. The semi-purified aqueous fractions were separated over Diaion HP-20SS resin to remove sugars and ascorbic acid. These fractions were then screened for antioxidant activity using the 1,1-diphenyl-2-picrylhydrazyl assay. Nine of the semi-purified fractions exhibited high antioxidant capacity. Cyanidin-3-O-β-glucopyranoside, an anthocyanin antioxidant, was identified from semi-purified aqueous fractions of the tropical fruit star apple (Chrysophyllum cainito), Surinam cherry (Eugenia uniflora), and jaboticaba (Myrciaria cauliflora). Delphinidin-3-O-β-glucopyranoside was identified from E. uniflora. [Copyright &y& Elsevier]
