The essential oils from three samples at the full blossom stage of wild Calamintha hispidula Boiss. and Reut. M. native of the mountain of Texanna, (Algeria), (one sample taken at the altitude of 625m south facing and the other two at 526m and 620m north facing), have been extracted by hydrodistillation and analysed by GC-MS. The oil yileds were 1,06%, 0,59% and 1,49%, respectively. The main essential oil constituents were isomenthone (68,7%, 68,2% and 57,9%), pulegone (18,1%, 15,1% and 22,2%) and piperitone oxide (3,6%, 6,6% and 22,2%), respectively. The variation in the yields of essential oils was considerable between the two altitudes 526m, 620m north facing. Isomenthone was found to be the major constituent in all cases.
