Natural antioxidants are more safe and healthy than synthetics antioxidants. The natural antioxidants aren’t limited to terrestrial sources. It’s documented that marine seaweeds are a rich source of natural antioxidant components. In this study, the antioxidant potential of two species namely Chaetomorpha sp and Colpomenia sinuosa and effect of different solvents on antioxidant compounds extraction were studied. The algal materials were extracted by conventional solvent extraction during 24 hours in room temperature (26-28 ) using acetone, ethanol, methanol (30/70%) and water (100%). Total phenolic contents, ferric reducing power, DPPH radical scavenging activity and total antioxidant capacity were measured in different extracts. The data showed acetone extracts have more potential to extraction antioxidant and polyphenolic compounds in comparison with other treatments. Also, it’s revealed that Chaetomorpha sp had the highest phenolic contents, ferric reducing power and total antioxidant capacity but lower radical scavenging activity than Colpomenia sinuosa. The difference in antioxidant compounds extraction can be related to the solvents type, target compounds and algal species. These algae can be applied in food and pharmaceutical industries as natural antioxidants sources.Journal
