STUDIES ON GC-MS PROFILING OF SOME SEAWEEDS OF MAHIM BEACH DIST. PALGHAR, MAHARASHTRA USING VARIOUS SOLVENTS

Objective: To investigate the bioactive constituents of Ulva lactuca, Sargassum prismaticum, and Sarconema filiforme using gas chromatography-mass spectrometry (GC-MS) analysis. Methods: 10 gm sample of each seaweed was successfully extracted with HPLC grade methanol and pet. ether with continuous shaking in a dark room for 36 h. The concentrated extracts were subjected to GC MS analysis. Results: The GC MS analysis of methanol and pet ether extracts of U. lactuca, S. prismaticum and S. filiforme show various types of phytocompounds screened under different R.T. Major compounds were 9-Octadecenoic acid (Z)-, phenyl-methyl ester, Stannane,1,3-dithian-2-ylidenebis[tributyl,Octadecane, 3-ethyl-5-(2-ethylbutyl) in methanol extract and Decane, 6-ethyl-2-methyl-, Tricosane and Sulfurous acid, 2-ethylhexyl hexyl ester in pet. ether. These bioactive compounds are considered as biologically and pharmacologically important. Conclusion: The three different extracts contain diverse bioactive compounds that were identified and characterized spectroscopically. Hence, the identification of different biologically active compounds in the extracts of seaweeds justifies further biological and pharmacological studies.
