Abstract


The specimens of Caulerpa racemosa ,Codium edule, Halimeda tuna, Ulva reticulata, Dictyota dichotoma, Sargassum crassifolium, and Turbinaria ornata were collected from the Sumba Islands waters, Indonesia. The crude methanol extracts of those specimens, n-hexane, dichloromethane and water fraction of Sargassum crassifolium were tested for antioxidant activity using the thiocyanate method. The methanol extracts of Caulerpa racemosa, Halimeda tuna, Ulva reticulata, Dictyota dichotoma, Sargassum crassifolium, and Turbinaria ornata showed antioxidant activity, but extracts of Codium edule did not show antioxidant activity. All of the Sargassum crassifolium fractions were active, but the water fraction of this extract was more active than the other fraction.
