Abstract: The seagrass Cymodocea serrulata was collected from Ramanathapuram coastal region and its antioxidant potential was determined. The ethanol extract showed the highest phenolic content of 284.94 mg/ml gallic acid equivalence and the ethyl acetate extract showed the highest flavonoids content of 40.18 mg/ml quercetin equivalence. The tannin content was higher at 264.71 mg/ml tannic acid equivalence in aqueous extract. The ethanol extract exhibited the highest 2,2 diphenyl-1-picrylhydrazyl (DPPH) and 2,2¢-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid (ABTS) radical scavenging activity with IC50 values of 44.47 µg and 2.5 µg, respectively. The ferric reducing ability and nitric oxide scavenging activity were efficient in both ethanol and aqueous extracts. The superoxide scavenging activity was high in hexane extract. The comparative antioxidant study of the subsequent extract of C. serrulata showed that the ethanol extract possesses the highest free radical scavenging property compared to other extracts. This may be due to the presence of high phenolic compounds. The study brings out the medicinal value of C. serrulata which can be used as a nutraceutical compound in various food and pharmaceutical industries.
