Abstract :Proximate and bioactive compounds insert ignore into journalissuearticles values(total phenolic, flavonoid, chlorophyll-a and total carotenoid contents); of three brown seaweeds insert ignore into journalissuearticles values(Dictyota dichotoma, Padina pavonica, Stypopodium schimperi); and a red seaweed insert ignore into journalissuearticles values(Jania rubens); from the north-eastern Mediterranean Sea insert ignore into journalissuearticles values(İskenderun Bay); were investigated seasonally at three sampling sites. Seasonal variations were found for all of the parameters studied. The highest ash content was in J. rubens insert ignore into journalissuearticles values(77.7%); in the spring. The results showed that J. rubens is a rich source with respect to mineral content. D. dichotoma had the highest crude protein content, whereas S. schimperi contained the most lipids. Phenolics ranged between 34.6 - 107.0 mg GAE/g dw. The highest total phenolics were found in S. schimperi in the summer, and the lowest in P. pavonica in the spring. The flavonoid contents insert ignore into journalissuearticles values(9.05-10.6 mg QE/g dw); were higher in brown seaweeds than that in the red seaweed. Moreover, chlorophyll-a and carotenoids levels were highest in D. dichotoma insert ignore into journalissuearticles values(4.53 and 2.83 mg/g, respectively); during the autumn. The results revealed that the biochemical composition of the examined seaweeds showed significant changes depending on the species, location and seasons.
