Description: From 200 genuses in Lamiacear family there are about 4000 species which one of them is Thymus. Existence of essence in these species is normal that uses for medicinal, nutritional, toiletry and health industry. The genus includes many species in Iran. This study was conducted components of essential oil in biomass of Thymus kotschyanus. Samples were collected in Zagheh area when plant was grown as flowering (in Lorestan Province) in 2011. First of all, anatomical investigations by using coloring and then samples in shadow dried and extracted by Clevenger device as Hydrodistilation method were produced. After producing essences, kind of components and percent of essential chemical components recognized and separated completely by using GC and GC/MS devices. According to components retention volume, retention time, Kovats retention index, mass spectrum and comparing those to standard components the results pointed out that 52 components (about 78.87% of essences in species) as main component such as; Thymol (32.77%), Gamma-terpineol (8.43%), Carvacrol (5.61%), Cynol (4.35%), Borneol (4.35%), Cis-Sabinene hydrate (2.87%), 4-terpineol (2.5%) and Gamma-gurjunene (2.17%). This study and most of the other researches had the same results according to main components of essences in the species but deal was different. It may affected by environmental and husbandry techniques such as; time of collecting, place of plant growing and climatic changes of region factors. These factors effect on biosynthesis of essential in time and place.
