Evaluation of Antioxidant Activity of Marine Algae-Extracts From Korea

Among 51 marine algae distributed along the Korean coast, Sargassum muticum (Yendo) Fensholt, Ishige okamurae Yendo, Ecklonia cava Kjellman, Polysiphonia morrowii Harvey, Dictyopteris undulata Holmes, Sargassm micracanthum (Kutzing) Endlicher, and Sargassum macrocarpum C. Agarch were found to have potent antioxidant activity. Additionally, the reducing power of marine algae-extracts was consistent with diphenyl-1-picryl hydrazyl (DPPH) radical scavenging activity. Because little is known about Sargassum muticum (Yendo) Fensholt, Ishige okamurae Yendo, Ecklonia cava Kjellman, Polysiphonia morrowii Harvey, Dictyopteris undulata Holmes, Sargassm micracanthum (Kutzing) Endlicher, and Sargassum macrocarpum C. Agarch, these marine algae may act as candidates for potent antioxidant food materials and are expected to have functional activity for foods and pharmaceuticals for treating oxidative diseases.
