Abstract: In this paper were present chromatographic data of Oregano vulgare essential oil from Kolonja area located in South-East Albania. Oregano vulgare is a flowering plant of mint family (Lamiaceae). It is native to the Mediterranean region. Oregano vulgare can found almost in all Albania areas. Since ancient times it has been used in culinary and traditional medicine. Aeral parts of Oregano vulgare were sampled in the end of the June for a five years period (2015-2019) in Kolonja area. The air dried leaves samples were subjected to European Pharmacopoeia apparatus (Clevenger type) for 4 hours to obtain Oregano vulgare essential oil. The leaves contains 1.43 - 1.74% essential oil. The chemical composition of the essential oils was analyzed using GC/FID technique. Oregano vulgare essential oil samples were injected 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. Monoterpenes were in higher percentage in all studied Oregano vulgare essential oil samples between 87.5% to 89.4%. Aromatic monoterpenes (p-Cymene, Thymol and Carvacrol) were found as the main constituents (74.4 - 81.2%) because of fenolic type for these essential oil. Profile of Oregano vulgare was the same for all years despite the differences in atmospheric conditions and harvesting time. Profile and leveles of Oregano vulgare samples from Kolonja, South-East Albania was similar with other reported studies from Balkan and Mediterrean area. plants.
