Objective: This study focuses on the antioxidant potential of Djibouti brown seaweed and their phenolic contents.

Methods: We evaluated the antioxidant potential by DPPH method (1,1-diphenyl-2-picrylhydrazyl) and their phenolic contents of seven Djibouti seaweed: Cytoseira myrica, Padina pavonica, Sargassum fluitans, Sargassum ilifolium, Sargassum sp, Turbinaria triquetra and Turbinaria turbinata. Also, we searched the secondary metabolites of these seaweeds.

Results: We obtain a higher antioxidant activity at 60,7±0,9 % and a higher phenolic content at 199,01±0,5 μg equivalent phloroglucinol (PGE)/g dry matter for Padina pavonica. A good linear correlation (R2 = 0,898) is observed between the antioxidant activity and the phenolic content of the seaweed studied. Also, two Padina pavonica collected in two different locations have different biochemical concentrations and antioxidant activity, suggesting the influence of the marine environment on the biosynthesis of secondary metabolites and the biological activities of seaweed.

The present study shows the presence of tannins, saponosides, flavonoids and steroid-terpenes.

Conclusion: The species studied show interesting antioxidant activities and can be consumed to prevent oxidative stress.

Keywords: Brown seaweed, Antioxidant activity, Polyphenols, Djibouti
