Essential oil variation in thymus daenensis subsp. daenensis cleak populations / Babak Bahreininejad in The journal of essential oil research, Vol. 22 N° 1 (Janvier/Fevrier 2010) 

Public ISBD [article]  in The journal of essential oil research > Vol. 22 N° 1 (Janvier/Fevrier 2010) . - pp. 48-51 Titre : Essential oil variation in thymus daenensis subsp. daenensis cleak populations Type de document : texte imprimé Auteurs : Babak Bahreininejad, Auteur ; Mehdi Mirza, Auteur ; Ahmad Arzani, Auteur Article en page(s) : pp. 48-51 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Thymus  daenensis  subsp.  daenensis  Lamiaceae  Essential  oil  composition  Carvacrol  Thymol  Geraniol  p-cymene  Chemotypes Index. décimale : 646 Résumé : The chemical composition of the essential oils in 11 populations of Thymus daenensis subsp. daenensis Cleak was evaluated using GC and GC/MS. Carvacrol, thymol and geraniol were found as the main constituents in the oils of the tested populations. Variation of the oils in populations was subjected to cluster analysis and three different chemotypes including carvacrol (47.3–80.1%), thymol (53.1–72.2%) and geraniol (65.6–75.7%) were identified. Other important components were β-caryophyllene (1.7–9%), p-cymene (0.1–10.9%) and γ-terpinene (0.1–7.8%). Although Thymus is known as having high thymol content in its oil, it is revealed that T. daenensis subsp. daenensis has also a high potential for carvacrol and geraniol constituents in the oil.

Evaluation of oil compositions of iranian mints (Mentha ssp.) / Hossein Zeinali in The journal of essential oil research, Vol. 17 N° 2 (Mars-Avril 2005) 

Public ISBD [article]  in The journal of essential oil research > Vol. 17 N° 2 (Mars-Avril 2005) . - pp. 156-159 Titre : Evaluation of oil compositions of iranian mints (Mentha ssp.) Type de document : texte imprimé Auteurs : Hossein Zeinali, Auteur ; Ahmad Arzani, Auteur ; K. Razmjoo, Auteur Année de publication : 2006 Article en page(s) : pp. 156-159 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Mentha  spicata  Mentha  longifolia  Lamiaceae  Essential  oil  composition  Cis-carveol  Terpinen-4-yl  acetate  Carvone  oxide  Piperitone  Menthol  Carvacrol  Isomenthone  Piperitone  oxide  p-cymene  Trans-carvyl  acetate Résumé : Dried aerial parts of 12 accessions of Iranian mints, three of which belonged to Mentha longifolia (L.) Huds. and the remaining of which belonged to Mentha spicata L., were used in this study. These were water distilled, and the essential oils analyzed by GC (FID) and GC/MS. Results indicated a significant variation in oil composition within the accessions. cis-Carveol (53.5–78.2%) was found as the main constituent in the oils of three M. longifolia accessions. The studied accessions of M. spicata indicated six different chemotypes, each of which was characterized by a high contribution of the following compound: 1 terpinen-4-yl acetate (51.7–55.3%); 2 carvone oxide (52.5%); 3 piperitone and menthol (49.3% and 15.7%, respectively); 4 carvacrol (49.6%); 5 isomenthone and piperitone oxide (39.1% and 23.3%, respectively); (6) p-cymene and trans-carvyl acetate (48.6% and 32.2%, respectively). The chemical variability of the tested accessions suggests the possibility of further exploiting and improving of the populations in a breeding program.
