ASSESSMENT OF ANTIOXIDANT PROPERTIES OF DRUPES
Keywords:
drupes, anthocyans, antiradical activity, vitamin CAbstract
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.
