Abstract:

Thymus Kotschyanus Boiss. & Hohen is one of the native medicinal plants of Iran. The chemical compositions of the essential oils were obtained from aerial part of 4 populations of T. Kotschyanus from Azarbayejangharbi province of Iran. The populations with three replications were arranged in a randomized completely block design (RCBD). The thyme populations that were collected during the full flowering phase and analyzed by gas chromatography (GC) and gas chromatography coupled to mass spectrometry (GC–MS).The major essential oils were identified in populations of Azarbayejangharbi-I (0.85%) and Azarbayejangharbi-II (0.84 %). There were identified 13 chemical compounds in the essential oils, the majority including, Thymol, Borneol, Gamma terpinene, Cymne (ortho) and (z) Caryophyllene. Also, the results demonstrated that the most phytochemical variation due to genetical factors. Thus we can management of these types chemical protection on the domestication, conservation and creation of gene banks, propagation and breeding of chemical types can be programmed.
