Abstract: The present study was aimed to explore the phytochemicals of Sargassum linearifolium (Turner) C.Ag. collected from Koothankuzhi coast, located in Tirunelveli district, in the south east coast of Tamil Nadu, India. The phytochemical analysis of the methanol extract was carried out using UV-Visible spectroscopy, FT-IR spectroscopy and HPLC. The UV-Visible spectrum of the methanol extract of Sargassum linearifolium showed the presence of the compounds separated from 200 to 1100nm with the absorption. The crude methanol extract of Sargassum linearifolium was passed into FTIR and it confirmed the presence of functional groups such as aromatic nitro compound, amides, alkyl chloride, organophosphorus compounds, amines, sulfonyl chloride, primary amines, ketones, phosphines and aliphatic compound. HPLC fingerprint of Sargassum linearifolium displayed seven prominent peaks at the retention time of 2.007min, 2.177min, 2.323min, 2.653min, 2.800min, 3.007min and 3.427min out of ten compounds separated.
