Green tea extracts (GTEs) [water (GTE-W) and 75% ethanol (GTE-E)] were investigated to characterize their propensities to act as antioxidants or as pro-oxidants by analyzing oxygen radical absorbance capacity (ORAC) and scavenging capacity for hydroxyl radical.

The olive oil oxygen radical absorbance capacity (DPPH assay) as a quality indicator
European Journal of Lipid Science and Technology, 2008AbstractThe antioxidant properties of some single components and the total antioxidant activity of extra‐virgin olive oil have been evaluated by the oxygen radical absorbance capacity (ORAC) method. The total ORAC of the extra‐virgin olive oil was found to be positively correlated with the concentration of total polyphenols, which are important to the ...

The oxygen radical absorbance capacity (ORAC) assay has been widely used to quantify peroxyl radical scavenging capacity of pure antioxidant compounds and antioxidant plant/food extracts. However, it has never been applied to natural compounds derived from microalgae-based dietary supplements, namely, phycocyanin (PC) and phycocyanobilin (PCB), for ...

Antioksidacijske metode: Metoda ORAC (engl. Oxygen Radical Absorbance Capacity)
2016Zbog brojnosti i kemijske raznolikosti molekula antioksidansa, različitih mehanizama njihova djelovanja, kao i ciljanih molekula na koje se želi ispitati njihov utjecaj, do danas je razvijen veliki broj antioksidacijskih metoda. Kako se niti jedna od postojećih metoda nije pokazala prikladnom da u potpunosti reflektira antioksidacijski kapacitet i ...
