Chemical variability of artemisia herba-alba asso growing wild in semi-arid and arid land (Tunisia) / Fatma Boukrich in The journal of essential oil research, Vol. 22 N° 4 (Juillet/Août 2010)

Various compositions were observed, dominated either by a single component (α-thujone, camphor, chrysanthenone or trans-sabinyl acetate) or characterized by the occurrence, at appreciable contents, of two or more of these compounds. These results confrmed the tremendous chemical variability of A. herba-alba.

The essential oil from artemisia herba-alba asso cultivated in arid land (South Tunisia) / Hédi Mighri in The journal of essential oil research, Vol. 21 N° 5 (Septembre/Octobre 2009)

During three years, the aerials parts were harvested (three levels of cutting, 25%, 50% and 75% of the plant), at full blossom and during the vegetative stage. The essential oil was isolated by hydrodistillation and its chemical composition was determined by GC(RI) and 13C-NMR. With respect to the quantity of vegetable material and the yield of hydrodistillation, it appears that the best results were obtained for plants cut at 50% of their height and during the full blossom. The chemical composition of the essential oil was dominated by β-thujone, α-thujone, 1,8-cineole, camphor and trans-sabinyl acetate, irrespective of the level of cutting and the period of harvest. It remains similar to that of plants growing wild in the same area.
