Description Not Available
The antioxidant activities of methanol extract and
its solvent fractions (n-hexane, dichloromethane and ethyl
acetate) of three red seaweeds (Hypnea musciformis , H.
valentiae, and Jania rubens) collected from the Gulf of
Mannar of South eastern coast of India were evaluated, using
different in vitro systems, viz., DPPH, ABTS, HO radical
scavenging activities, H2O2 scavenging ability, Fe2+ ion chelating
ability and reducing potential. Folin–Ciocalteu method
was used to determine the total phenolic content of the
extracts/fractions, and the results were expressed as mg of
gallic acid equivalent (GAE)/g of the seaweed extracts/
fractions. Thiobarbituric acid-reactive substances (TBARS)
inhibition assay was employed to assess the ability of the
seaweed extracts/fractions to inhibit lipid oxidation.
