The antioxidant properties of Mapo Tangelo fruit and leaves extracts were investigated. The con- tent of health-promoting components (total phenolics, flavonoids and ascorbic acid) were evaluat- ed by spectrophotometric assays. Higher concentrations of total phenolics, flavonoids and ascor- bic acid were found in peel samples extracted with boiling water, followed by leaves extracted with boiling ethanol. The radical-scavenging activity of the extracts was evaluated by different in vitro tests (total antioxidant activity, DPPH, ABTS and β-carotene bleaching tests). The trend observed for bioactive compounds was confirmed by antioxidant activity assays and good correlation val- ues were obtained with total phenolics, flavonoids and ascorbic acid.

Abstract
The antioxidant properties of Mapo Tangelo fruit and leaves extracts were investigated. The con- tent of health-promoting components (total phenolics, flavonoids and ascorbic acid) were evaluat- ed by spectrophotometric assays. Higher concentrations of total phenolics, flavonoids and ascor- bic acid were found in peel samples extracted with boiling water, followed by leaves extracted with boiling ethanol. The radical-scavenging activity of the extracts was evaluated by different in vitro tests (total antioxidant activity, DPPH, ABTS and β-carotene bleaching tests). The trend observed for bioactive compounds was confirmed by antioxidant activity assays and good correlation val- ues were obtained with total phenolics, flavonoids and ascorbic acid.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
