    (Addis Ababa Universty, 2007-03) Tesfaye, Berhanu; Asfaw, Nigist (PhD)
    A study of the essential oil of Artemisia schimperi was undertaken. The volatile constituents of the aerial parts of Artemisia schimperi have been examined by GC, 1HNMR and 13C-NMR and 18 components comprising 87.4% of the oil have been identified by GC using Kovat’s index and in some cases by comparison with standard samples. The oil contained as main components: p-cymene 19.6%, Artemisyl acetate, 12.7%, Geranial 10.5%, Artemisia alcohol 9.2%, and Limonene 6.6%. The oxygenated compounds constitute 63.6% of the oil. One compound was isolated and the structure was elucidated based on spectroscopic technique and by comparison of the data with the reported in the literature.
