Sažetak
Marine organisms are rich natural resource of many biologically active compounds. Among them, seaweeds are well known as an excellent source of phytochemicals with good biological activities. Although exposed to high oxidative living environment, seaweeds suffer no oxidation damage, which suggest that their cells have antioxidant defence system. Adriatic seaweeds have not yet been fully investigated, thus this study presents the first results on biological potential of three Adriatic brown seaweeds from the Phaeophyceae class. The research included Adriatic marine algae extracts of Padina pavonica (Linnaeus) Thivy, Cystoseira amentacea var. stricta Montagne and Cystoseira compressa (Esper) Gerloff & Nizamuddin. The total phenolic content in seaweed extracts was determinated by Folin-Ciocalteu method. 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 Briggs-Rauscher (BR) oscillating reaction. Extract of C. amentacea was superior in comparison to other two extracts in both phenolics and related antioxidant efficiency. The total phenolic content in extract from this specie was 785 mg GAE/L, while other two extracts contained almost 8-fold (P. pavonica) and 10-fold (C. compressa) lower amounts. Similar results were obtained for antioxidant activities: reducing activity by FRAP method, as well as for free radical scavenging activity using DPPH radical, while in BR method extracts of P. pavonica and C. compressa did not show any activity. The obtained results emphasize C. amentacea seaweed as a potentially good source of biologically active compounds and open the numerous possibilities of its application in food, cosmetic and/or pharmaceutical industry.
