The six seaweeds namely Ulva lactuca (L), Caulerpa racemosa C. Agardh, Sargassum wightii Greville, Padina tetrastomatica Hauck, Gracilaria corticata var. cylindrica J. Ag., and Acanthophora spicifera (vahl.) Boergesen, collected from the Gulf of Mannar were screened for the presence of Phycochemical constituents like primary and secondary metabolites both qualitatively and quantitatively. The present investigation revealed that saponin and polyphenol were absent in the acetone extract of seaweeds and other extracts posses all the phycoconstituents. Maximum percentage of protein (210.31±6.3 mg/g), carbohydrate (317.11±9.51mg/g) and phenol (3.02±0.09mg/g) were recorded in Sargassum wightii whereas lipid (81.95±2.45mg/g), anthocyanin (0.202±0.006mg/g) in Padina tetrastomatica and tannin (35.87±1.07 mg/g) in Acanthophora spicifera. Phycochemical analysis of these seaweeds revealed the presence of potential pharmaceutical activity.
