Seeds of Salvia verbenaca L. collected at full ripeness stage from three different regions in Tunisia (Sebelet Ben Ammar, Somâa, Sers) were subjected to fatty acids extraction and GC analysis. Results showed important total fatty acid contents, high unsaturated fatty acid proportions and a balanced source of n-6 and n-3 fatty acids in seeds. We noticed that most fatty acid compounds were insensitive to regional variations which emphasize the nutraceutical use of seeds. Besides, essential oils were extracted from seeds by hydrodistillation and analyzed by GC and GC/MS. Chromatographic analysis revealed the identification of forty five compounds. The major constituents were camphor (33,8%), α-pinene (48,0%), and octane (27,4%) in samples collected from Sabelet Ben Ammar, Sers and Somâa, respectively. This variability suggests an important effect of region on essential oil composition and can lead to a large range of naturally occurring volatile compounds with valuable industrial and pharmaceutical outlets.
