In this work the content of anthocyans, vitamin C and the antiradical activity of selected species of drupes were evaluated by the spectrophotometric measurement. The highest concentration of anthocyan pigment was found out in blackthorn (Prunus spinosa L.). Cherries (Prunus avium L.) variants Újfehértói fürtös, Záhoráčka and Morella contain half times less of this plant pigment than the samples of blackthorn. Selected species of drupes are sources of natural vitamin C. Morellos (Prunus cerasus L.) contain higher concentration of ascorbic acid than cherries, but they have similar amount of this vitamin than plums (Prunus domestica L) variants Domáca veľkoplodá and Stanley. Surprisingly, it was evaluated exceptionally high value of antiradical activity in blackthorn, which reaches value: 461.25 % (EC50 = 0.1084 ± 0.0101). We can say that observed plant materials are important sources of nutritive compounds for composing dietary menu in healthy nutrition as well as for prophylaxis of toxic free radical accumulations along with connected civilization diseases.
