Many seaweeds, most notably brown algae, are suitable for human consumption. These plants have various possible biological actions and significant phytochemical components. The ethylacetate and dichloromethane extracts of Sargassum flutans were examined for their phytochemical composition and in vitro antioxidant activities in our research. The antioxidant capacity was evaluated using the DPPH (2, 2-diphenyl-1-picrylhydrasyl) method and the reducing power. The DPPH radical scavenging activity of an antioxidant is a well-known indicator of its capacity to eliminate free radicals. Sargassum flutans ethylacetate extracts had demonstrated effective DPPH radical reducing capability. The extract's capacity to eliminate DPPH radicals increased with concentration. The typical antioxidant and positive control employed was ascorbic acid. Ethylacetate extracts from Sargassum flutans showed more reducing power than dichloromethane. The phenolic content was also determined using the Folin-Ciocalteau reagent to evaluate the extracts' impact on total antioxidant activity. The results show that the percentage of phenolic compounds of the Sargassum futans DCM extracts was higher than that of the ethylacetate extracts. Finally, it is also noteworthy to mention that, the DPPH scavenging, reducing power, and phenolic content in these extracts of maritime macroalgae were remarkably concentration dependent.
