ABSTRACT
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. Investigation and comparison on essential oil constituents of two populations T. hyrcanicum collected from two localities. 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. 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-beta-farnesene [10.7%] were found as the major components. From Rostamabad sample E- beta-Farnesene [60.6%] and E-beta-Farnesene [15.0%] were the most abundant. 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
