【摘要】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. 【总页数】7页(205-211) 【关键词】
