The composition of the essential oils of Nepeta ispahanica Boiss. and N. binaludensis Jamzad was investigated by means of GC, GC±MS and 1 H-NMR spectra of the main compounds. 1,8-Cineole was the most abundant component in both oils: Nepeta ispahanica (66%) and N. binaludensis (42%). However, nepetal

✦ Synopsis
The composition of the essential oils isolated from the aerial parts of Teucrium heterophyllum L'HCr. collected during the flowering period and the vegetative phase of the plant, was analysed by GC and GC-MS. Both oils, which were obtained in a yield lower than 0.05% (vlw), were dominated by sesquiterpenes (51% and 48% of the oils from flowering and vegetative plant material, respectively). T-Cadinol (21% and 17%) and a-cadinol (11% and 9%) were the main components of the sesquiterpene fraction. The monoterpenes attained 29% and 34%, a-pinene (16% of both oils) being the major constituent of this fraction.
