The intention of this research aimed to investigate the antioxidant capacity of seaweeds collected in Rameswaram along the south coast of India. The antioxidant activity of four seaweeds; Turbinaria conoides, Sargassum squarrossum, Gracilaria foliifera and Dictyota dichotoma were determined in this study. The highest level of DPPH activity is seen in the DCM fraction, which is as follows: Turbinaria conoides> Sargassum squarrossum> Gracilaria foliifera >Dictyota dichotoma. The DCM fraction of Gracilaria foliifera exhibited the highest total antioxidant activity. (105.44 ± 0.52 mg AA/g). The DCM fraction of Gracilaria foliifera had the strongest ferric reducing antioxidant power (FRAP) among four seaweeds (1.246±0.004 mg AA/g). The ethyl acetate and hexane fraction has less reducing ability as compared with DCM fraction. The total phenol content of the DCM fraction is greater than that of the ethyl acetate and hexane fractions. The DCM fraction of Sargassum squarrossum has the highest phenol content (3.71 mg/g) and Turbinaria conoides (3.50 mg/g). In comparison to ethyl acetate and hexane fractions, DCM fraction of all seaweeds has strong antioxidant activity and total phenolic content. A search for new natural resources, such as seaweeds used as food and antioxidants, has proven to be nutritious, cost-effective, and environmentally benign. Due to their antioxidant properties, seaweeds are promising prospects for medicinal, pharmaceutical, and nutritional applications.
