Three plant species belonging to Compositae, Chenopodiceae and Potamogetonaceae were collected from Burullus Lake.Hydrocarbon, sterol and fatty acid composition of each species were investigated and identified quantitatively using GLC technique.The result demonstrated that, the unasaponifiable matter of Inula erithmoides Halimione portulacoides and Potamogeton pectinatus was composed of, respectively 74.7% hydrocarbons and 25.3% sterol compounds; 73.6% hydrocarbons and 26.5% sterol compounds;100% hydrocarbons.Two sterols, namely cholesterol and stigmasterol, were detected in extracts of Inula erithmoides and Halimione portulacoides but at different concentrations.The analysis of saturated and unsaturated fatty acids indicated that the species studied differed in the number and concentration of fatty acids.
