GC- MS Analysis of Essential Oil Extract from Leaves and Stems of Tarragon (Artemisia dracunculus L.).

Abstract

The aim of this study was to investigate the phytochemical diversity of essential oil of leaves and stems of tarragon (Artemisia dracunculus L.) with main functional components, essential oils extracted by hydro-distillation using Clevenger apparatus and the phytochemical compound screened by GC-MS instrument. Forty bioactive phytochemical compounds were identified in the essential oil of (Artemisia dracunculus L.). The detection of phytochemical compounds is based on the peak area, retention time, molecular weight, molecular formula, chemical structure, MS Fragment ions and pharmacological actions. GC-MS analysis of (Artemisia dracunculus L.) revealed to  the existence of the α-pinene, Camphene, β-Thujene, L-β-Pinene, 3-Octanone, β.-Myrcene, dl-5-Hydroxylysine,N,N,o-tris(tert-butyldimethylsilyl)-,tert-butyldimethylsilylester, α-Terpinene, m-Cymene, Eucalyptol,  γ-Terpinene, cis-Sabinene hydrate,  (+)-4-Carene,β-Methylisoallylbenzene  , Linalool, Chrysanthenone, Camphor, Evonine, Carbamic acid, [2-[[1-(diphenoxyphosphinyl)-2-phenylethyl]amino]-2-oxo-1-, (-)-Borneol , (-)-terpinen-4-ol (3-Cyclohexen-1-ol,4-methyl-1-(1-methylethyl)-,(R)-), Phenol,2-ethyl-4,5-dimethyl-, α-Terpineol (3-Cyclohexene-1-methanol,.alpha.,.alpha.,4-trimethyl-,(S)-), Borneol, cis-Verbenone,cis-Carveol, (-)-cis-Myrtanol, Dihydrocarveol (Cyclohexanol,2-methyl-5-(1-methylethenyl)-), p-Benzoquinone,2-(3-hydroxy-3,7,11,15,19,23,27-heptamethyl-6,10,14,18,22,26-oct, Methyl nerolate ( 3,6-Octadienoicacid,3,7-dimethyl-,methylester,(Z)-), Isopiperitenone (2-Cyclohexen-1-one,3-methyl-6-(1-methylethenyl)-,(S)-), bornyl ester, 2-Methylbicyclo[4.3.0]non-1(6)-ene, Piperitenone, Cyclopentane,1-acetoxymethyl-3-isopropenyl-2-methyl-, 3,5-Heptadienal,2-ethylidene-6-methyl-, Caryophyllene, 1,4,7,-Cycloundecatriene,1,5,9,9-tetramethyl-,Z,Z,Z-, Caryophylleneoxide, 1-Oxaspiro[2.5]octane,5,5-dimethyl-4-(3-methyl-1,3-butadienyl)-, The analysis of Artemisia dracunculus L. leaves and stems showed the presence of Alkenes, Aliphatic fluoro compounds, Alcohols, Ethers, Carboxylic acids, Esters, Nitro compounds, Alkanes, Aldehydes, Ketones compounds. These founding confirm that beside the uses of Tarragon as seasoning due to containing a wide range of essential oil diversity, it can be also useful for various herbal therapy, as anti-inflammatory, cardiac tonic analgesic, antipyretic, antiepileptic, laxative, antispasmodic, carminative remedy and anti-asthmatic.
