ANTIOXIDANT POTENTIAL AND SOME MEDICINAL PROPERTIES OF AGAR FORMULATIONS FROM SEAWEED Gracilaria filiforms IN COASTAL TAMIL NADU

Fractionated polysaccharides were produced by extracting the water soluble polysaccharides (WSP) from the seaweed Gracilaria filiforms (FPs). The FP was structurally characterised using FT-IR, and the antioxidant capacities were assessed utilising tests for total antioxidant, 2,2 diphenyl-1-picrylhydrazyl (DPPH), and hydrogen peroxide radical scavenging (H2O2). All of the antioxidant experiments revealed increased scavenging activity in FPs from Gracilaria filiforms. The FPs from all the seaweed shown admirable anticoagulant properties. The greatest larvicidal activity on Anopheles stephensi and Aedes aegypti was demonstrated by FPs from Gracilaria filiforms. The outcomes clearly demonstrate the FPs from the three Indian seaweeds that were chosen as prospective future functional foods, nutraceutical substances, and insecticides.
