Abstract
U ovom radu analizirano je 45 uzoraka meda od čega je 34 uzorka cvjetnog meda i 11 uzoraka meda livade. Uzorci su iz različitih područja Hrvatske, Bosne i Hercegovine te Slovenije. Određen je udio ukupnih fenola pomoću modificirane Folin-Ciocalteu metode te antioksidacijska aktivnost pomoću dviju metoda, FRAP i DPPH. Udio ukupnih fenola se kretao u rasponu od 12,25 do 257,25 mg GAEkg-1 meda, ˝radical scavenging˝ aktivnost izražena kao IC50 u rasponu od 0,8301 do 43,0648 mgmL-1 te antioksidacijska aktivnost određena pomoću FRAP metode u rasponu od 91,9310 do 407,7931 μM Fe(II) 10%-tne otopine meda.
Abstract (english)
In this assay, 45 samples of honey were analyzed out of which 35 was from floral origin and 11 was meadow honey. Samples were colected from diferent regions of Croatian, Bosnian and Herzegovinian and Slovenian teritory. Total phenolic content was determined by the modified Folin-Ciocalteu method and antioxidant activity by two methods, FRAP and DPPH. Phenolic content ranged from 12,25 to 257,25 mg GAE/kg of honey, ˝radical scavening˝ activity expressed as IC50 from 0,8301 to 43,0648 mg/mL and antioxidant activity determined by FRAP method in range from 91,9310 to 407,7931 μM Fe(II) of the 10% honey solution.
