Marine organism especially marine macro algae commonly known as seaweeds are a rich source of structurally novel and biologically active metabolites. Secondary and primary metabolites produced by seaweeds may be potential bioactive compounds of interest in the pharmaceutical industry. Seaweeds also have the valuable medicinal components such as antibiotics, laxatives, anticoagulants, anti-ulcer products and suspending agents in radiological preparations. The present study was carried out to screen the preliminary phytochemicals of Colpomenia sinuosa (Mertens ex Roth) Derb. Et Sol. from Manapad coast, Thoothukudi district, in the south east coast of Tamil Nadu, India. The preliminary phytochemical analysis was conducted in seven extracts namely methanol, acetone, chloroform, ethyl acetate, petroleum ether, hexane and benzene by Harborne method. The preliminary phytochemical analysis showed the presence of alkaloids, anthocyanin, anthraquinones, cardiac glycosides, catechin, coumarins, diterpenes, emodins, flavonoids, glycosides, leucoanthocyanin, lignins, phenols, phlobatannins, quinones, saponins, steroids, tannins, terpenoids and triterpenoids. Among the various phytochemicals studied, alkaloids, lignins, saponins and tannins showed the maximum presence, being found in six different extracts and quinones was found in only one extract. From the results, it was noted that the extracts of Colpomenia sinuosa (Mertens ex Roth) Derb. Et Sol. was noted to be the presence of a number of active secondary metabolites.
