Abstract
U okviru ovog diplomskog rada istraženi su prisutnost i antioksidacijski učinak fenolnih spojeva u metanolnim i etanolnim ekstraktima listova odabranih vrsta roda Salvia s područja Hrvatske (S. brachyodon, S. fruticosa, S.glutinosa, S. nemorosa, S. officinalis, S. pratensis, S. sclarea i S. verticillata). Primjenom metode tankoslojne kromatografije dokazana je prisutnost ružmarinske kiseline i luteolin-7-O-glukozida u listovima svih uzoraka. Kvercitrin je prisutan samo u vrsti S. ... More verticillata, a rutin u vrstama S. brachyodon, S. fruticosa i S. officinalis. Antioksidacijski učinak etanolnih ekstrakata ispitan je pomoću tri spektrofotometrijske metode u usporedbi s troloksom i EDTA. Utvrđena je sposobnost hvatanja DPPH radikala (IC50: 3,88-7,93 μg/mL), redukcije iona željeza(III) ( IC50: 9,43- 18,36 μg/mL) te keliranja iona željeza(II) ( IC50: 163,55-1592,53μg/mL). Dobiveni rezultati pokazuju da istraživane biljne vrste sadrže flavonoide i fenolne kiseline koji doprinose njihovim antioksidacijskim učincima. Less
Abstract (english)
The presence of phenolic compounds and their antioxidative effect in methanolic and ethanolic leaf extracts of selected species of the Salvia genus from Croatia (S. brachyodon, S. fruticosa, S.glutinosa, S. nemorosa, S. officinalis, S. pratensis, S. sclarea and S. verticillata) were studied in this diploma thesis. The presence of rosmarinic acid and luteolin-7-O-glucoside was detected by thin-layer chromatography in all leaf samples. Quercitrin was present only in the S.... More verticillata extract and rutin was detected in leaf extracts of S. brachyodon, S. fruticosa and S. officinalis. The antioxidative effects of ethanolic extracts were determined by using three spectrophotometric methods in comparison to trolox and EDTA. The abilities of scavenging DPPH radical (IC50: 3.88- 7.93 μg/mL), reduce ferric ions (IC50: 9.43-18.36 μg/mL) and chelate ferrous ions were determined. The obtained results have shown that the studied plant species contain flavonoids and phenolic acids which contribute to their antioxidative effects. Less
