    Abstract

    Antioxidants are compounds that protect cells against the damaging effects of reactive oxygen species, such as singlet oxygen, superoxide, peroxyl radicals, hydroxyl radicals and peroxynitrite. Antioxidants can cancel out the cell-damaging effects of free radicals. Seaweeds have become a major food ingredient in products especially in Japan, Korea and China. In Asia, seaweeds have been used for centuries in the preparation of salads, soups and also as low-calorie foods. In Bali, there are three types of seaweeds that have been consumed as vegetables and food. These seaweeds local name are Bulung Boni (Caulerpa spp.), Bulung Sangu (Gracilaria spp.), and Euchema spinosum. People in Bali have been consumed these seaweeds for a long time a go, but until this time there are no research or publication about the antioxidant activity of these seaweed, so this research aims to know the total carotenoids content, total phenolics , and antioxidant activity of these seaweeds. The research resulted that total carotenoids of Bulung Boni(Caulerpa spp.) higher than Bulung Sangu (Gracilaria spp.), and E. spinosum. Total carotenoid are 37,249.00 µg/ 100 g in Bulung Boni , 1,777.63 µg /100 g in Bulung Sangu (Gracilaria spp,), and 1,989.930 µg/ 100 g sample in E. spinosum. Total phenolic in E. spinosum is 2,5473 %, Caulerpa spp. 1, 9216 %, and Gracilaria spp. 0,8970 %. Antioxidant activity or free radical scavenging of Bulung Boni (Caulerpa spp.) is 28.0857 % , Bulung Sangu (Gracilaria spp.) 9.6714 %, and E. spinosum is 2.2000 %. Key words : Caulerpa spp., Gracilaria spp., E. spinosum, total carotenoids, total phenolic,antioxidant activity
