In Vitro Antioxidant Study On Gracilaria Opuntia Seaweed From Southeast Coast Of India

Abstract

Objectives: In vitro antioxidant activities of selected seaweed Gracilaria opuntia were evaluated.

Methods: The extraction of phytochemicals from Gracilaria opuntia were carried out with different solvents like ethyl acetate, ethanol and distilled water. The in vitro anti-oxidant studies were measured by DPPH assay, Hydrogen peroxide assay.

Results: The preliminary screening shows the presence of tannins, flavonoids, terpenoids, steroids, reducing sugar, polyphenols. The total antioxidant activity were higher shows at 500µg/ml in Gracilaria opuntia extracts.

Conclusion: This seaweed could be considered for curing disease from oxidative deterioration which can be further screened for various biological activities.
