Abstract
Listovi masline (Olea europea L.) posjeduju veliki potencijal kao prirodni antioksidansi. Danas je sve veći broj istraživanja koji potvrđuju blagotvorne učinke lišća masline na ljudsko zdravlje, kao i mogućnost njihove primjene u prehrambenoj industriji. Cilj ovog rada bio je ispitati antioksidacijski kapacitet lišća masline sortiLastovka, Levantinkai divlje masline korištenjem različitih spektrofotometrijskih metoda temeljenih na različitim mehanizmima djelovanja: FRAP (engl. Ferric Reducing Antioxidant Power), ORAC (engl. Oxygen Radical Absorbing Capacity) i DPPH (engl. 2,2-diphenyl-1-picrylhydrazyl assay) metoda. Obzirom na sadržaj ukupnih fenola i antioksidacijski potencijal određen FRAP metodom, najbolju redukcijsku sposobnost pokazao je ekstrakt lista divlje masline. Najveći antioksidacijski kapacitet i sposobnost neutralizacije hidroperoksil radikala pokazao je ekstrakt kultivirane sorte Levantinka. Rezultati svih testiranih uzoraka ukazuju na veliki biološki potencijal ekstrakta lista masline te mogućnosti njegove primjene u prehrambenoj industriji.
Abstract (english)
Olive leaves (Olea europea L.) have great potential as natural antioxidants. Today, a growing number of studies confirm the beneficial effect of olive leaves on human health, but also the possibility of their use in the food industry. The aim of this study was to examine antioxidant activity of olive leaves of Lastovka, Levantinkaand wild oliveusing different spectrophotometric methods based on different mechanisms of action: FRAP (Ferric Reducing Antioxidant Power), ORAC (Oxygen Radical Absorbing Capacity) and DPPH (2,2-diphenyl-1-picrylhydrazyl assay) method. Based on the content of total phenolics and antioxidant potential determined by FRAP method, the best reducing ability was obtained for wild olive leaf extract. The highest antioxidant capacity and ability to neutralize hydroperoxyl radicals was shown by the extract of the cultivated olive variety Levantinka.The obtained results for all tested samples indicate a great biological potential of olive leaf extractsand the possibility of their application in the food industry.
