Some species of this genus are important medicinal plants and their extracts have been used formedicinal purposes. In this investigation aerial parts of Nepeta sintenisii Bornm. was subjected tohydrodistillation and the chemical composition of the isolated essential oil was analyzed by GC/MSmethod for first time. Forty constituents (96.5% of the total oil) were identified of which 4aβ,7α,7aβ-nepetalactone (23.4%), elemol (16.1%), E-β-farnesene (9.5%), 1,8-cineole (8.2%), cis-sabinene hydrate(6.5%), β- bisabolene (4.2%) and germacrene-D (3.5%) were the main components. The constituents ofthe volatile oil of N. sintenisii is similar to the composition of the other Nepeta genus.
