Green macroalgae Ulva lactuca, brown macroalgae Taonia atomaria and Padina pavonica are spread in the Turkish Levantine Sea. There is limited information about antioxidant activities and fatty acid composition of these species from Levantine Sea. In this study was to determine and compare antioxidant activities, vitamin and fatty acid (FA) composition of U. lactuca, T. atomaria and P. pavonica. The analysis was made with HPLC and GC device. g. Then, the results were analyzed using SPSS software. The results showed; palmitic acid (C16:0) as the most abundant saturate fatty acid (21-41%). The green algae was rich palmitic acid (C16:0) (41.68%). Monounsaturated fatty acids (MUFAs) were major components (39.81–42.89%). The total MUFA content for U. lactuca was 40.63%, P. pavonica 42.89% and for T. atomaria 38.81%. Oleic acid (C18:1 n-9) was the most abundant MUFA in all the species analyzed. Eicosapentaenoic acid ( C20:5 n-3) and arahidonic acid (C20:4 n-6) were found in significant levels in T. atomaria. P. pavonica and T. atomaria showed similar amounts of C18 and C20 PUFAs contents. In T. atomaria eicosopentaenoic acid (EPA, C20:5n3) accounted 4.78% of total fatty acids. PUFA/SFA ratio in T. atomaria was 1.10%, U. lactuca; 0.26% and for P. pavonica 0.68%.The total phenolic contents ranged from 0.96 to 2.22 mg gallic acid equivalents per 1 g of dry macroalgae material. Phenolic content of the water extract of T. atomaria (2.22 mg GAE /g) was higher than that of the water extract of P. pavonica and U. lactuca. It has been thought that the amount of α-tocoferol was higher than the other lipophilic vitamins in all the three species tested. In Conclusion; these species can be used as food and in food industry.
