Composition chimique de l’huile essentielle d’ Artemisia herba-alba provenant de la région de Biskra (Algérie)

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. L’huile essentielle (HE) d’Artemisia herba-alba Asso (Asteraceae), obtenue par entrainement a la vapeur des sommites, a ete etudiee par CPG-FID et CPG-SM. La determination de l’HE correspond a 0,95ml pour 100 g de matiere seche. Quarante-six composes correspondant a 92,61% ont ete identifies. L’HE contient en majorite de l’acetate de cis-chrysanthenyle (25,12%), du 2E,3Z-2-ethyliden-6-methyl-3,5-heptadienal (8,39%), de l’α-thujone (7,85%), de l’acetate de myrtenyle (7,39%), de la verbenone (7,19%), de la chrysanthenone (4,98%). La composition chimique est tres specifique pour cette plante algerienne.
