Isolation and Characterization of secondary metabolites With antioxidant activity from seaweeds from Southeastern coasts of india

Abstract

Seaweeds offer valuable bioactive molecules with antioxidative properties, newlineand are abundantly available in the Gulf of Mannar region of the Southeastern newlinecoasts of India. This study aimed to evaluate the antioxidative properties of different seaweed newlinespecies available in this region and isolating the compounds with potential radical scavenging newlineactivity. The methanol extract and solvent fractions (n-hexane, dichloromethane and ethyl newlineacetate) of the brown seaweeds Turbinaria conoides, Turbinaria ornata, Anthophycus newlinelongifolius, Sargassum plagiophyllum, Sargassum myriocystum, Padina tetrastomatica, newlinePadina gymnospora and Stoechospermum marginatum and the red seaweeds Laurencia newlinepapillosa, Gelidiella acerosa and Acanthophora spicifera collected from the Gulf of Mannar newlineregion of Mandapam were screened for potential antioxidant properties by different model newlinesystems. newline
