Phenols, flavonoids and nonflavonoids in wild blueberry

Istraživanje je provedeno na 35 uzoraka (zamrznute divlje borovnice) ubranih na 7 različitih lokacija u RH. Određivani su ukupni fenoli, neflavonoidi te flavonoidi spektrofotometrijskim metodama. Prosječne vrijednosti kreću se od 5603,845-7039,7322 mg GAE kg-1 jestivnog dijela za ukupne fenole; 4282,6362-5617,5168 mg GAE kg-1 jestivog dijela za flavonoide, te 1321,2084-1516,9306 mg GAE kg-1 jestivog dijela za neflavonoide. Prema dobivenim rezultatima uočena je velika antioksidacijska aktivnost u plodovima divlje borovnice.Experiments were conducted on 35 samples (frozen wild blueberry) harvested on 7 different locations in the Republic of Croatia. Total phenolic, flavonoids and nonflavonoids were determined with spectrophotometric methods. The amount of total phenolics, flavonoids and nonflavonoids was in average 5603,845-7039,7322 mg GAE kg-1; 4282,632-5617,5168 mg GAE kg-1; 1321,2084-1516,9360 mg GAE kg-1, respectively. The determined values indicate high antioxidant capacity in samples of wild blueberries
