ABSTRACT
OBJECTIVE@#In vitro antioxidant activities of three selected Indian seaweeds viz., Halimeda tuna (H. tuna), Turbinaria conoides (T. conoides) and Gracilaria foliifera (G. foliifera) were evaluated.@*METHODS@#Total antioxidant activity, total phenolic content, and reducing power of crude methanol and diethyl ether extracts were determined.@*RESULTS@#Total phenolic content and total antioxidant activity were higher (1.231±0.173 mg GAE/g, 1.675± 0.361 mg GAE/g) in T. conoides respectively. Reducing power of crude methanol extract increased with concentrations of the extract. The Fourier transform-infra red spectrum analysis revealed the presence of polyphenolic signals. The seaweed extracts displayed moderate antioxidant activity compared to gallic acid standard.@*CONCLUSIONS@#The seaweeds could be considered for curing diseases from oxidative deteriorations.
