Abstract:
Sideritis, known as mountain tea is a genus of flowering plants well known for their use as herbal medicine, commonly as a tisane. The Sideritis herbs were sampling in June, 2016 in different stations of mountains of South of Albania. The air dried plant samples were subjected to European Pharmacopoeia apparatus (Clevenger type) for 6 hours to obtain Sideritis oil in 1 ml Toluene. The chemical composition of the essential oils was analyzed using GC/FID technique. The oil of each Sideritis sample was injected in a Varian 450 GC. VF-1ms capillary column (30m x 0.33mm x 0.25 um) were used for separation of compounds. Alfa-Pinene (27.2 - 32.7 %), beta-Pinene (37.9-45.4 %), beta-Phellandrene (2.2 - 4.4%), alfa-Copaene (1.6 - 3.5 %) and Bicyclogermacene (1 - 1.6 %) have been identified as the main components of the essential oils of Sideritis samples from South of Albania. Other compounds were found to be lower than 1%. The composition of the essential oil extracted from the Sideritis plant is associated with type, time of sampling and geographic position. The reported levels of the main compounds were the same with reported levels from other Balkan areas. |
