Abstract

The paper deals with the chemical composition and antioxidant activity of aqueous extracts from leaves of two highbush blueberry varieties: ‘Bluecrop’ and ‘Northland’. The study revealed differences in the content of the analyzed components. Leaves of cv. ‘Bluecrop’ were characterized by a higher content of chlorophyll, flavonoids and anthocyanins, while the leaves of cv. ‘Northland’ contained more reducing sugars and total phenolic acids, tannins, and essential oils. Capacity of neutralizing the free radicals (DPPH) in leaves of both tested cultivars was found at comparable levels.
