  Abstract:  The fatty acids composition of the seed oils from the 10 sunflower inbred lines and 4 hybrids obtained to the National Agricultural Research and Development Institute Fundulea, was qualitatively and quantitatively determined using analytical methodology. Procedure of research for detection lipids content in sunflower seeds was the conventional extraction, using International Organization for Standardization (ISO). Soxhlet method (SO-extraction) involves the gravimetric determination of sunflower oil using the petroleum extract from oilseeds. The result of Soxhlet method has been detecting a large variability point of view of lipid percent content in hybrids and inbred lines of sunflower. The fatty acids profiles were obtained using laboratory analytical techniques, the methyl ester analysis were made through gas-chromatography. The groups of the fatty acids: C14:00, C15:00, C16:00, C16:01, C17:00, C18:00, C18:01, C18:02, C18:03, C20:00, C20:1 and C22:0 was determined by experiments. Great variation has been observed in fatty acid content of sunflower seeds from 14 Romania genotypes.
