Abstract

Istraživanje je provedeno na 50 uzoraka (zamrznutih plodova planinske jarebike) izuzetih s različitih lokaliteta dviju makrolokacija u RH– Velebita i Gorskog kotara. Ukupni fenoli određeni su spektrofotometrijski primjenom Folin-Cicalteu metode, a dobivene prosječne vrijednosti kreću se od 9651,411 do 15463,18 mg GAE kgˉ¹ jestivog dijela uzorka. Na temelju dobivenih rezultata može se zaključiti da plodovi planinske jarebike imaju visoku antioksidacijsku aktivnost što im daje anti-kancerogeno, anti-upalno, anti-dijabetičko i kardioprotektivno djelovanje na ljudski organizam.

Abstract (english)

Experiment was conducted on 50 samples (frozen rowanberry fruit) harvested on different localities in two macrolocations in the Republic of Croatia - Velebit and Gorski kotar. Total phenols were determined by spectrophotometric application of the Folin-Ciocalteu method, and the obtained average values ranged from 9651,411 to 15463,18 mg of GAE kgˉ¹ of the edible part of the sample. Based on the obtained results, it can be concluded that mountain rowanberry fruits have a high antioxidant activity, which gives them anti- carcinogenic, anti-inflammatory, anti-diabetic and cardioprotective effects on the human body.
