Abstract
Moderan način života povećava razinu oksidativnog stresa stoga brojne studije nastoje pronaći nove, prirodne supstance koje je lako unijeti u organizam i koje će pomoći ljudskom organizmu u borbi sa slobodnim radikalima. Upravo u te supstance ubrajamo fenolne spojeve koje nalazimo u biljkama. U ovom radu je ispitan fenolni sastav plodova roda Rosa. Analiza je provedena na četiri različita uzorka ploda vrste Rosa canina L. i dva uzorka ploda Rosa hybrida spp. koristeći Folin-Ciocalteu metodu određivanja ukupnih fenola i tekućinsku kromatografiju visoke djelotvornosti (High-performance liquid chromatography, HPLC) metodu za određivanje fenolnog profila. Rezultati pokazuju visoki udio ukupnih fenola kod svih ispitanih uzoraka te je HPLC metodom dokazano prisustvo fenolnih kiselina i flavonoida od kojih su najzastupljeniji galna i protokatehinska kiselina te epikatehin i katehin. U vrstama Rosa hybrida spp. je dokazan veći udio fenolnih spojeva i bolji fenolni profil u usporedbi s Rosa canina vrstama.
Abstract (english)
Modern lifestyle increas oxidative stress level, therefore numerous studies try to find new, natural substances that are easy to consume and help with free radicals. These substances include phenolic compounds found in plants. This paper examine the phenolic composition of Rosa fruits. The analysis was performed on four different fruit samples of Rosa canina L. and two fruit samples Rosa hybrida spp. using the Folin-Ciocaltea method for the determination of total phenols and the High-performance liquid chromatography (HPLC) method for the determination of the phenolic profile. The results show a high proportion of total phenols in all tested samples and the HPLC method proved the presence of some phenolic acids and flavonoids, the most common of which were gallic and protocatechinic acid, and epicatechin and catechin. Rosa hybrida spp. showed a higher total phenolic content and a better phenolic profile compared to Rosa canina species.
