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 sesquit

โฆ Synopsis
The composition of the essential oils of Nepeta ispahanica Boiss. and N. binaludensis Jamzad was investigated by means of GC, GCยฑMS 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, nepetalactone (25%), linalol (4%), a-terpineol (4%) and b-pinene (3%) were major constituents of N. binaludensis. The structures of 1,8-cineole, nepetalactones and b-pinene were conยฎrmed by their 1 H-NMR spectra.
