Description 507-518
Antioxidant
activities of crude methanol extracts and fractions of the seaweed species viz.
Bryopsis plumosa (BP), Dictyopteris australis (DA) and Gracilaria
pudumadamensis (GP) of Indian waters were evaluated and correlated with
their

phytochemical
contents. In DPPH assays the most promising antioxidant sample was the crude
methanol extract (BPM), which was comparable with standard antioxidant BHT. In
the superoxide radical activity assays no sample in the group was

as
active as BHT, however the promising ones were DAM, DAE
and GPM, GPE, GPH (subscripts M, E and H stand
for the respective methanol extracts and their ethyl acetate and hexane
fractions). In the Fe2+ chelating activity assays EDTA

showed
far stronger activity than those of the promising samples. In reducing power
assays BPM, BPE, and BPH showed comparable
activity with BHT at a concentration 0.5 mg/mL. Thus these seaweed species
would be of potential utility as a source of natural antioxidants.
