Chemical Composition of the Essential Oil from Stems of Artemisia marschalliana Sprengel. Obtained by Microwave Extraction.

The genus Artemisia is the largest and most distributed genera within the family Asteracea. Thirty-four species of the genus are found in Iran, of which two are endemic: A.melanolepis Boiss. And A.kermansis Podl [1]. Many members of the genus Artemisiaare aromatic plants. Many Artemisia species are distributed in Europe, Asia, and North America. Artemisia species are well known for their volatile oil that is used in the food and pharmaceutical industries and in folk medicine to treat gastrointestinal diseases [2]. The chemical composition of essential oils from various Artemisia spp. have been analyzed in previous studies. Previously we reported the essential oil from the aerial parts of A.turcomanica. 1,8-Cineol (5.5%(, spathulenol (15.2%), camphor (14.8%), santolina alcohol (14.6%) and trans-β- terpineol (11.6%) were the main constituents [3]. The aim of our study is to identify the constituents of the essential oils of leaves and flowers of A.marschalliana, growing wild in East Azarbaijan, Iran, in July 2015. The oils were obtained by solvent free microwave extraction and analyzed by GC and GC/MS.The stems of Artemisia marschalliana was collected from East Azarbaijan, Iran, in July 2015. The oil was obtained by solvent free microwave extraction and analyzed by GC and GC/MS.Fourteen constituents, representing 95.3% of the total components in the oil of A.marschalliana were identified. The oil was characterized by large amounts of aliphatic hydrocarbons (68.8%) with dodecane (41.4%), tridecane (12.4%) and undecane (11.5%) being the major constituents. The sesquiterpenes amounted to (18.0%) with spathulenol (13.9%) being the important one. In the oil of the plant we couldn‘t identify any monoterpene.
