Different growth stages of Ulva lactuca were harvested from different biotopes in the Suez Canal during February through April 2003 and subjected to bioassay detect substances with biological activity. The total alcoholic extract algal material was fractionated into light petroleum, chloroform, ethyl acetate, fatty acid methyl esters unsaponifiable matter. effect extracts more pronounced as antifungal than antibacterial. Petroleum had prominent on Aspergillus niger. Fatty ester a greater Chrysosporium sp, whereas, unsaponifable acetate affected Fusarium sp. Bacillus subtilus found be sensitive all solvent extracts. Ethyl Staphylococcus aureus. Unsaponifable Sarcina lutea. un-saponifable fraction analyzed by GLC, GC/MS, TLC. GLC analysis revealed presence twelve acids, palmitic, oleic margaric acids represented 70.34, 20.9 2.26%, respectively, while hydrocarbon C-28 major one (63.76%).
