Free-Radical-Scavenging and Antioxidant Activities of Secondary Metabolites from Reddened Cv. Annurca Apple Fruits

Forty-three secondary metabolites were isolated and characterized from cv. Annurca apple fruit, an apple variety cultivated in the south of Italy. This apple cultivar undergoes a typical reddening treatment after collection. All of the compounds were characterized on the basis of their spectroscopic...

Description
Summary:Forty-three secondary metabolites were isolated and characterized from cv. Annurca apple fruit, an apple variety cultivated in the south of Italy. This apple cultivar undergoes a typical reddening treatment after collection. All of the compounds were characterized on the basis of their spectroscopic data. The compounds were tested for their radical-scavenging and antioxidant activities by measuring their capacity to scavenge DPPH• (2,2‘-diphenyl-1-picrylhydrazyl radical), H2O2, and NO (nitric oxide) and to inhibit the formation of methyl linoleate conjugated diene hydroperoxides or TBARS (thiobarbituric acid reactive species). Keywords: Malus domestica cv. Annurca; secondary metabolites; triterpenes; phenolic fatty acid esters; polyphenols; free-radical-scavenging activity; antioxidant activity.
