L'huile essentielle (HE) d'Artemisia herba-alba Asso (Asteraceae), obtenue par entraînement à la vapeur des sommités, a été étudiée par CPG-FID et CPG-SM. La détermination de l'HE correspond à 0,95 ml pour 100 g de matière sèche. Quarante-six composés correspondant à 92,61 % ont été identifiés. L'HE contient en majorité de l'acétate de cis-chrysanthényle (25,12 %), du 2E,3Z-2-éthyliden-6-méthyl-3,5-heptadiènal (8,39 %), de l'α-thujone (7,85 %), de l'acétate de myrtényle (7,39 %), de la verbénone (7,19 %), de la chrysanthénone (4,98 %). La composition chimique est très spécifique pour cette plante algérienne.Mots clés : Artemisia herba-alba -Armoise blanche -Composition de l'huile essentielle -Acétate de cis-chrysanthényle -Chémotype Chemical composition of the essential oil of Artemisia herba-alba issued from the district of Biskra (Algeria)Abstract: Artemisia herba-alba Asso (Asteraceae) essential oil (EO), obtained by hydrodistillation from aerial parts, and was investigated using GC-FID and GC-MS techniques. The EO yield, based on dry weight, was 0.95% (v/w). Forty six components corresponding to 92.61% of the oil were identified. The EO contained in majority: cis-chrysanthenyl acetate (25.12%); (2E,3Z) 3,5-heptadienal-2-ethyliden-6-methyl (8.39%); α-thujone (7.85%); myrtenyl acetate (7.39%); verbenone (7.19%), chrysanthenone (4.98%). Chemical composition was very specific for this Algerian plant.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
