This study was conceived to investigate the composition of four essential oils (EOs) extracted by hydrodistillation from four parts (leaves, stems, leaves/stems, roots) of Artemisia herba-alba growing wild in the Center of Tunisia. For this, Artemisia herba-alba aerial and roots parts were shade dried with ventilation at room temperature. Then, plant different parts were cut into small pieces and subjected to hydrodistillation using a Clevenger-type apparatus. The gas chromatography (GC) analyses were accomplished with a HP-5890 Series II instrument. The main results showed a total of 152 compounds detected and identified by GC and GC-MS and accounting for 91.3-99.7% of the whole oil. The four oils were characterized by the predominance of monoterpene derivatives (68.2-99.5%) and the major volatile constituent was α-thujone (18.2-45.5%). Qualitative and quantitative differences between the four essential oils have been noted for some compounds. The main compounds of leaves essential oil were α-Thujone (45.5%), β-Thujone (11.4%), trans-sabinyl acetate (10.1%), 1,8-Cineole (7.4%) and camphor (6.8%). α-Thujone (27.5%) was also the main compound in the essential oil of leaves/stems, followed by camphor (22.9%), 1,8-cineole (8.3%), β-thujone (8.2%) and camphene (5.6%). The essential oil of stems was dominated by α-Thujone (28%) followed by β-Thujone (11.4%) and chrysantenone (11%). In the essential oil of roots, α-thujone was less represented (18.2%), followed by camphor (14.6%) and curcumen-15-al (14.3%). It is important to mention that curcumen-15-al has been reported for the first time in Artemisia herba-alba oil Our results revealed avariability in the chemical composition and the yield of the EOs from Artemisia herba-alba. Moreover, curcumen-15-al is a new chemotype first found in Artemisia herba-alba from Tunisia.
Essential Oil Composition of Artemisia herba-alba from Southern Tunisia
Molecules, 2009
The composition of the essential oil hydrodistilled from the aerial parts of 18 individual Artemisia herba-alba Asso. plants collected in southern Tunisia was determined by GC and GCMS analysis. The oil yield varied between 0.68% v/w and 1.93% v/w. One hundred components were identified, 21 of of which are reported for the first time in Artemisia herba-alba oil. The oil contained 10 components with percentages higher than 10%. The main components were cineole, thujones, chrysanthenone, camphor, borneol, chrysanthenyl acetate, sabinyl acetate, davana ethers and davanone. Twelve samples had monoterpenes as major components, three had sesquiterpenes as major components and the last three samples had approximately the same percentage of monoterpenes and sesquiterpenes. The chemical compositions revealed that ten samples had compositions similar to those of other Artemisia herba-alba essential oils analyzed in other countries. The remaining eight samples had an original chemical composition.

The intraspecific chemical variability of essential oils (50 samples) isolated from the aerial parts of Artemisia herba-alba Asso growing wild in the arid zone of Southeastern Tunisia was investigated. Analysis by GC (RI) and GC/MS allowed the identification of 54 essential oil components. The main compounds were b-thujone and a-thujone, followed by 1,8-cineole, camphor, chrysanthenone, transsabinyl acetate, trans-pinocarveol, and borneol. Chemometric analysis (k-means clustering and PCA) led to the partitioning into three groups. The composition of two thirds of the samples was dominated by athujone or b-thujone. Therefore, it could be expected that wild plants of A. herba-alba randomly harvested in the area of Kirchaou and transplanted by local farmers for the cultivation in arid zones of Southern Tunisia produce an essential oil belonging to the a-thujone/b-thujone chemotype and containing also 1,8-cineole, camphor, and trans-sabinyl acetate at appreciable amounts. Introduction.-Artemisia herba-alba Asso (Asteraceae) is a silvery-green, perennial dwarf shrub growing in semiarid and arid climates. This species is known as desert wormwood in English, armoise blanche in French, and chih in Arab, and it is characteristic of the steppes and deserts of the Middle East (Egypt and Israel), North Africa (Tunisia, Algeria, and Morocco), and Southern Europe (Spain and Italy), extending into the Northwestern Himalaya [1]. In Tunisia, A. herba-alba is found from the mountains around Jebel Oust (Fahs) until the South of the country [2] [3]. The aerial parts of A. herba-alba are widely used in the traditional medicine to treat diabetes, bronchitis, diarrhea, and neuralgias [4-6]. The essential oil of this species is known for its disinfectant, anthelmintic, and antispasmodic therapeutic virtues [7]. Also the antibacterial and the antispasmodic activities of A. herba-alba essential oil from various chemotypes have been examined [8]. Moreover, the oil exhibited antileishmanial [9], spasmolytic [10], and antimutagenic activity against the carcinogen benzopyrene [11]. According to Lawrence [12] and Salido et al. [13], the aerial parts of A. herba-alba produce an essential oil characterized by a tremendous chemical variability. Various chemotypes have been reported in almost all the countries where A. herba-alba grows wild. Briefly, two types of oils could be distinguished: i) oils with a composition dominated by one major compound, i.e., camphor, a-thujone, b-thujone, chrysanthenone, chrysanthenyl acetate, or davanone, and ii) oils characterized by the occurrence at appreciable contents of two or more of these compounds.

Background: Artemisia saharae Pomel is a new taxon of Artemisia herba-alba Asso (Asteraceae) which is endemic to Tunisia and Algeria. This shrub, commonly known as white wormwood or desert wormwood, is largely used in folk medicine and as a culinary herb. The bulks aromatic plants come from wild populations whose essential oils compositions as well as their biological properties are severely affected by several factors such as geographic conditions. Therefore, the aim of the present work is to provide more information about the influence of altitude variation on the essential oil composition, antimicrobial and antioxidant properties of Artemisia saharae growing wild in the same geographical area. Results: Essential oils were extracted by hydrodistillation of leaves and flowers of the plant collected from seven different altitudes of the Baten Zamour region (southwest of Tunisia). The highest essential oil yields (2.70-2.80%) were obtained for populations of high altitudes. Seventy-five compounds, representing 92.78 to 96.95% of the total essential oils, were separated and identified. Essential oils were characterized by very high percentage of oxygenated monoterpenes (52.1-72.6%) which constituted the predominant class. From the analyzed populations, the major compounds (>7%) were α-thujone, β-thujone, chrysanthenone, camphor, chrysanthenyl acetate, and sabinyl acetate. Sabinyl acetate which was detected in some populations at relatively high percentages (7.7-10.8%) seems to be characteristic to Southern Tunisian A. saharae. The studied essential oil showed a chemical diversity depending on the population altitude as revealed by linear discriminant and cluster analyses.
Chemical variability of Artemisia herba-alba Asso essential oils from East Morocco
Chemical Papers, 2010
Chemical compositions of 16 Artemisia herba-alba oil samples harvested in eight East Moroccan locations were investigated by GC and GC/MS. Chemical variability of the A. herba-alba oils is also discussed using statistical analysis. Detailed analysis of the essential oils led to the identification of 52 components amounting to 80.5–98.6 % of the total oil. The investigated chemical compositions showed significant qualitative and quantitative differences. According to their major components (camphor, chrysanthenone, and α- and β-thujone), three main groups of essential oils were found. This study also found regional specificity of the major components.
Abstract: The aerial parts of Artemisia vulgaris and A. absinthium (Asteraceae) were hydrodistilled to produce the oils in the yields of 0.5 % (v/w) and 0.8 % (v/w) respectively. The oils were analyzed by GC and GC-MS. Thirty five and Thirty one components were identified representing 87.1 % and 90.8 % of the oils, respectively. The main compounds of A. vulgaris were β-thujene (36.0 %), α-thujene (13.6 %), chrysanthenon (5.6 %), piperitone oxide (4.1 %) and caryophyllene oxide (3.1 %) whereas chamazulene (28.6 %) (-) spathulenol (7.4 %), 1-phellandrene (6.1 %), β- calacorene (5.6 %), sabinene (5.5 %), cis-epoxyocimene (4.5 %) and 1H-indene (3.9 %) were the major constituents of A. absinthium. The results discussed with the genus patterns.
Essential Oil Composition of Artemisia annua L. ‘Asha’ from the Plains of Northern India
Journal of Essential Oil Research, 2002
Chemical composition of the essential oils obtained from the aerial parts of Artemisia annua at vegetative, pre-bloom, bloom and post-bloom stages was determined using GC and GC/MS analysis. The yields of essential oil were 0.14%, 0.34%, 0.64% and 0.54% (w/w), respectively at different growth stages. A total of 67 compounds were identified. Oxygenated monoterpenes (39.0%-57.0%) constituted the main fraction of the oils followed by sesquiterpene hydrocarbons (11.8%-26.2%) and monoterpene hydrocarbons (4.2%-15.1%). The main compounds identified in all the analyzed samples were camphor (28.6%-31.7%), 1,8-cineole (2.1%-20.8%), germacrene D (3.8%-12.0%), β-caryophyllene (2.8%-6.9%), trans-β-farnesene (0.7%-4.5%), α-pinene (0.5%-2.4%), p-cymene (0.8%-2.3%) and terpinen-4-ol, (0.9%-2.1%). The results indicated considerable quantitative variations in both oil yield and chemical composition at different growth stages and artemisia ketone and artemisia alcohol were found to be absent in the oils.

The composition of essential oils of Artemisia annua from seven localities of West Cameroon and from Luxembourg were determined. The essential oils were extracted by micro-chamber thermal extractor (μ-CTE) and analyzed by Thermal Desorption plus Gas Chromatography coupled to Mass Spectrum (TD/GC/MS). According to the results obtained in this study, artemisia ketone was present only in the samples from Luxembourg. Limonene, eucalyptol and copaene were also found to be present in higher concentration in the Luxembourg samples while various localities of Cameroon were found to be richer in camphor and menthol. Camphor was the major compound among the thirteen identified and quantified from the extracts of both countries even though its yield was>60% in the Cameroon samples and 35.67% in that of Luxembourg. Climatic and culture conditions could be responsible for the variation in chemical composition of the samples studied. This work was carried out in an accredited laboratory (ISO 1...
