Abstract: In this study chromatographic data of Laurus nobilis L. essential oil from different areas of Albania were presented. Laurus nobilis is an aromatic evergreen tree, part of the flowering plant family Lauraceae. It is native to the Mediterranean region and can be found almost in all areas of Albania. It has been used in culinary and traditional medicine since ancient times. Leaves of Laurus nobilis were sampled in June, 2018 in six different areas of Albania (Tirana, Durres, Lezhe, Lushnje, Elbasan and Pogradec). The air dried leaf samples were subjected to European Pharmacopoeia apparatus (Clevenger type) for 4 hours to obtain Laurus nobilis essential oil. The leaves contained 1.21 - 1.44% essential oil. The chemical composition of the essential oils was analyzed using GC/FID technique. Laurus nobilis essential oil samples were injected manually in a Varian 450 GC. VF-1ms capillary column (30 m x 0.33 mm x 0.25 um) were used for separation of terpene compounds. Oxygenated monoterpenes were in higher percentage for all studied samples. 1,8-Cineole (Eucalyptol) was the main compound followed by Linalool, Limonene, Linalyl acetate, alfa- and beta-Pinene. Their profile was similar for all studied areas despite the differences in geographic and atmospheric conditions. Profile and percentage of terpenes in Laurus nobilis L. samples from Albania was similar with other reported studies from Balkan and Mediterrean area.
