Abstract
U ovom radu analizirana su 32 uzorka bagremovog meda hrvatskog podrijetla (Varaždinska županija, sezona 2010). Određen je sadržaj ukupnih fenola pomoću modificirane Folin-Ciocalteu metode, te antioksidacijska aktivnost pomoću dviju metoda, DPPH i FRAP. Sadržaj ukupnih fenola kretao se u rasponu od 23,55 mg GAE/kg meda do 74,09 mg GAE/kg meda. „Radical scavenging“ aktivnost, izražena kao IC50, u rasponu od 3,68 do 201,96 mg/mL, a antioksidacijska aktivnost, izražena kao FRAP vrijednost, od 14,93 do 120,94 μM Fe (II) 10 % otopine meda. Utvrđena je linearna korelacija između udjela ukupnih fenola i antioksidacijske aktivnosti određene DPPH metodom (r = 0,7808) te udjela ukupnih fenola i antioksidacijske aktivnosti određene FRAP metodom (r = 0,9722), kao i između rezultata dobivenih FRAP i DPPH metodom (r = 0,8830).
Abstract (english)
In this assay, 32 samples of acacia honey from croatian territory (county of Varaždin, season 2010) were analyzed. Phenolic content was determined by the modified Folin-Ciocalteu method and antioxidant activity by two methods, DPPH and FRAP method. Phenolic content ranged from 23,55 mg GAE/kg of honey to 74,09 mg GAE/kg of honey. Antioxidant activity expressed as IC50 ranged from 3,68 mg/mL to 201,96 mg/mL, and antioxidant activity expressed as FRAP value from 14,93 to 120,94 μM Fe (ІІ) of the 10 % honey solution. Linear correlation was established between the total phenolic content and DPPH values (r = 0,7808), and also between the total phenolics and FRAP values (r = 0,9722), as well as between FRAP and DPPH values (r = 0,8830).
