Biologically active compounds of berries and leaves of Vaccinium corymbosum L.

Quantitative content of the sum of phenolic compounds and anthocyanins in their composition were study. The level of antiradical activity (ARA) in the berries and leaves of Vaccinium corymbosum L. was measured.

The maximum content of the sum of phenolic compounds was observed in Blueray, Bluerose, Caroline Blue, Herbert, Jersey, Nelson cultivars. In the cultivars which have been studied the quantity of anthocyanins in the composition of phenolic compounds ranged from 0.01 to 0.8 % in green berries, and from 22 to 52 % in mature ones. Earlyblue, Duke, Bluecrop, Bluegold cultivars were characterized by the greatest quantity of phenolic compounds in leaves.

The presence of a close positive correlation between the level of antiradical activity and the content of secondary metabolites of phenolic nature was determined. The differences in phenolic substances accumulation in blueberry cultivars obtained by in vivo and in vitro methods were revealed.

It was shown that the proteomic profile of the highbush blueberry plants together with genetic passports can being used to determine the cultivar's identity of Vaccinium corymbosum L.
