Abstract
The goal of this study was to investigate the antioxidant properties of crude extracts of Hypnea pannosa, a red alga from the Hypneaceae family that was collected from the Gulf of Manner in Rameswaram, Tamilnadu. The extracts were assayed for DPPH radical scavenging, Hydroxyl radical, ABTS radical, Superoxide radical, and reducing power. Ethanol and methanol extracts were found to exhibit significant antioxidant activity. Ethanol extract of H. pannosa showed a good significant activity for ABTS and DPPH free radicals (118.56% and 124.30%). This holds great promise for the use of Hypnea pannosa as a source of strong antioxidant compounds.
