Sažetak
In order to define the optimal extraction method, the influence of different extraction temperatures (20, 40 and 60ºC) as well as the effect of the used solvent (water, ethanol) during ultrasound assisted extraction of macroalgae Dictyota dichotoma and Padina pavonica were studied. The extracts were analysed spectrophotometrically for total phenolics, flavonoids, and tannins, while the presence of individual phenolics was detected by HPLC. The antioxidant activity was evaluated by employing three methods ; Ferric Reducing/Antioxidant Power (FRAP), scavenging of the stabile 2, 2-diphenyl-1-picrylhydrazyl (DPPH) radical, and Oxygen Radical Antioxidant Capacity (ORAC). The higher extraction yield for total phenolics, flavonoids and tannins was obtained using alcoholic solvent, while the general conclusion about the applied temperature was not established. These extracts showed also highest antioxidant activity with extremely high reducing capacity (690-792 mM TE) and ORAC values (38.7-40.8 mM TE in 400- fold diluted extracts) detected for D. dichotoma ethanolic extracts. The results obtained by principal component analysis (PCA), which permits simple representation of different sample data and better visualisation of their correlations, point out great influence of flavonoids and tannins on tested biological properties of algae extracts what is interesting for future studies dealing with their application in foods, cosmetics and pharmaceuticals.
