Phytochemical Compounds and Antioxidant Activity in Different Cultivars of Cranberry (Vaccinium Macrocarpon L).

Cranberries can be a component of a healthy diet, because they are a great source of health-promoting compounds and nutrients. The aims of this study were to evaluated phytochemicals and antioxidant activity in 6 cultivars of cranberry fruit grown in Poland. The content of polyphenols, carotenoids, chlorophylls, and triterpenoids were determined with the use of UPLC-PDA-MS/MS, although antioxidant activity was examined with DPPH, ABTS, and FRAP assays. The cvs. "Franklin," "Howes," and "Stevens" were characterized by the highest concentration of total polyphenols (4219, 3995, and 3584 mg/100 g dm), triterpenoids (3582, 3671, and 3451 mg/kg dm), carotenoids (9.75, 8.52, and 7.94 mg/kg dm), and antioxidant activity (ABTS: 226, 264, 246; FRAP: 102, 139, 124; DPPH: 235, 320, 284 μmolTE/g dm), making these 3 cultivars especially recommendable for consumption. Furthermore, a positive correlation between content of phytochemicals and antioxidant activity was found.

UNASSIGNED

The manuscript "Phytochemical compounds and antioxidant activity in different cultivars of cranberry (Vaccinium macrocarpon L)" represents cultivars commonly grown in Poland that maybe beneficial offer the food industry, to develop attractive foods with a high content of biologically active substances.
