Chemical variation in the oil of artemisia verlotiorum lamotte of french origin harvested at a vegetative stage and during flowering / Fabien Juteau in The journal of essential oil research, Vol. 17 N° 3 (Mai-Juin 2005) 

Public ISBD [article]  in The journal of essential oil research > Vol. 17 N° 3 (Mai-Juin 2005) . - pp. 254-256 Titre : Chemical variation in the oil of artemisia verlotiorum lamotte of french origin harvested at a vegetative stage and during flowering Type de document : texte imprimé Auteurs : Fabien Juteau, Auteur ; Véronique Masotti, Auteur ; Josette Viano, Auteur Année de publication : 2006 Article en page(s) : pp. 254-256 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Artemisia  verlotiorum  Asteraceae  Essential  oil  composition  α-thujone  1,8-cineole  β-caryophyllene  Seasonal  variation Résumé : Artemisia verlotiorum essential oils, obtained by hydrodistillation of the aerial parts collected in southern France, were analyzed by GC and GC/MS. Among the identified constituents, α-thujone (55% and 44%), 1,8-cineole (5% and 15%), β-caryophyllene (13% and 7%) and β-thujone (5% and 11%), were the main components of the oils, from the vegetative and flowering plants, respectively. The proportions of the oxygenated compounds seemed to increase during flowering.

It was found to be rich in sesquiterpenoids and characterized by spathulenol (19.5 %) and two alkanols, tetradecanol (10.2%) and dodecanol (9.3%). Furthermore, the oil was screened for its antimicrobial activity against five microbial strains. However, only a moderate antimicrobial effect of this oil was found against four of the five tested strains.
