Background: The genus Teucrium (Lamiaceae) is comprised of about 340 species widespread over the world. In the Flora Iranica, this genus is represented by 12 species, of which 3 are endemic. Several Teucrium species are used in Iranian folk medicine as medicinal plant. There is no study on the volatile oil of Teucrium hyrcanicum in the literature. Objective: Investigation and comparison on essential oil constituents of two populations T. hyrcanicum collected from two localities. Methods: The aerial parts of T. hyrcanicum were collected from road of Khalkhal-Asalem and Rostamabad shade dried and then essential oil extracted by means of hydrodistillation and analyzed with GC and GC/MS. Results: The essential oil yields were 0.25 and 0.20 (w/w) based on dry weight of plant, respectively. 38 and 15 compounds were idedtified, representing 93.1% and 93.3% of the total oils, respectively. In the oil obtained from Khalkhal-Asalem. Hexahydrofarnesyl acetone (12.7%), linalool (11.7%) and E-β-farnesene (10.7%) were found as the major components. From Rostamabad sample E- β-Farnesene (60.6%) and E-α-Farnesene (15.0 %) were the most abundant. Conclusion: The results showed that the difference in the volatile constituents could be considered as chemotaxonomic significance and it may be attributed to their different ecological and geographical origin factors.
