Abstract

The genus of Nepeta presents 67 species in Iran, most of them are endemic. One of these endemic species is N heliotropifolia. In this research the essential oil of N heliotropifolia was investigated in three different stage of plant growth.The aerial parts of N heliotropifolia at before flowering, beginning of flowering and complete flowering were collected from Hamedan province.Essential oils isolated by hydro-distillation from the aerial parts of three samples, were analyzed by a combination of capillary GC and GC/MS. The yields of essential oils were obtained 0.75%, 0.63% and 0.4% (w/w) respectively. So the oil yield of N heliotropifolia was decreased from before flowering stage to complete flowering stage.Thirty-six components were identified in the oils. The main constituent of the essential oil at before flowering stage was LIMONENE (40.1%), that decreased by plant growth. The second main component of the oil in this stage was b-pinene (11.1%) that increased to 23.3% in the beginning of flowering, then decreased in fool flowering. The other main compounds of the oils were 1,8-cineole, b-caryophyllene,(Z)- b-farnesene, g-mmurolene abd bicyclogermacrene.
