In Vitro Antioxidant Activity Of Red Seaweeds Of Methanolic Extracts From Rameshwaram Coast

Abstract

Natural extracts of marine macroalgae are widely recognized for their antioxidant.The aim of this study was to evaluate the antioxidant activity of methanolic extracts of two marine algae, Haloplegma duperreyi and Halymenia floresii. The extracts were assayed, DPPH free radical scavenging capacity, Hydroxyl and ABT+ radical scavenging assay in both algae. Methanolic extracts of both algae were found to exhibit significant antioxidant activity. Among two seaweeds, Haloplegma duperreyi exhibited a good capacity for DPPH free radical scavenging capacity, Hydroxyl and ABT+ radical scavenging assay (54.20± 0.50, 56.20 ±0.70, and 39.59.27 ±0.30% inhibition at 500 µg mL-1 respectively) .
