This research aimed to explore the antioxidant potency of leaf extracts of Syringodium isoetifolium seagrass. In this study, seagrass leaves were collected from the local tribe’s source, dried and extracted with water, alcohol, hydro alcohols, acetone and n-hexane. Phytochemical investigation on extracts was performed using chemical and gas chromatography-mass spectrometric techniques. It reveals that the extracts are enriched with pharmacologically active compounds such as phenol, polyphenol, alkaloid, glycoside, saponin, flavonoids, dicarboxylic acids and other constituents. Later, the crude extracts were estimated for antioxidant activity using different in vitro methods such as 2,2-diphenyl-1-picryl-hydrazyl-hydrate, total antioxidant, nitric oxide, superoxide anion and hydroxyl radical scavenging activities. The result demonstrated that the extracts exhibited higher radical scavenging activity as compared to the ascorbic acid. Among the different extracts, the hydroalcoholic extract had shown an excellent antioxidant activity due to the existence of more potent phytochemicals.
