The Essential Oil ofArtemisia judaicaL. from Algeria

Chemical composition and biological activities of Artemisia judaica essential oil from southern desert of Jordan

“…Oxygen containing monoterpenes provide the more representative group of constituents (68.7 %), being piperitone (30.4%), camphor (16.1%) and ethyl cinnamate (11.0%) the main compounds. These results are quite similar to those obtained with the oils from A. judaica growing in Egypt (ElMassry et al, 2002;Abd-Elhady, 2012), that are characterized by high amounts of piperitone, camphor and ethyl cinnamate and are markedly different from the oils from Southern Israel (Negev), that have high amounts of Artemisia ketone and Artemisia alcohol and from the oils from Algeria and Libya with high levels of piperitone, chrysanthenone, cischrysanthenyl acetate and cis-chrysanthenol (Charchari, 2002;Dob & Chelghoum, 2006, Janaćković et al, 2015. Compounds listed in order to their elution on the SPB-1 column.…”

Chemical composition of the essential oil ofArtemisia judaica L. from Algeria

“…30 The composition of the oil isolated from A. judaica L. investigated here by us was compared to that obtained from the same species collected in different geographical sites in the world. [8][9][10][11][12][13] For comparison purposes, only the main components and irregular monoterpenes were considered ( Table 2). Piperitone was found as the main compound of A. judaica essential oils from the following sites: In-Amenas (Algeria), Tamanraset (Algeria), Farsh Freah (Sinai), Wadi A-Dir (Sinai), Sinai Peninsula and Western desert (Egypt).…”

“…The essential oil was obtained in relatively medium yield (0.70% on a dry weight basis); the odour of the oil was representative of the aerial parts and was yellow in colour. Some differences in yield were observed among samples of A. judaica of different origins: 4,8,10,11,13 Egypt, 0.6% and 0.91-4.0%; Israel, 0.24-3.2%; Algerian desert (Tamenrasset), 1.4%. Hence, it may be supposed that there is a relationship between yield and geographical origin ( Table 2).…”

“…Identification of constituents was made on the basis of their retention indices on DB-1 column and by computerized matching of the acquired mass spectra with those stored in the spectrometer database, using the NIST mass spectral library and by comparison with the literature. [8][9][10][11][12][13][15][16][17][18][19][20][21][22][23][24][25][26] Table 1 lists the compounds identified in the oil of the Algerian A. judaica L. in order of elution from DB-1 column, their percentages, their retention indices on the DB-1 column and the techniques used for their identification. The essential oil was obtained in relatively medium yield (0.70% on a dry weight basis); the odour of the oil was representative of the aerial parts and was yellow in colour.…”

“…6,7 Several papers have already been published on the essential oil composition of Artemisia judaica L., [8][9][10][11][12] but only one on Algerian Artemisia judaica L., collected in Tamanrassat desert. 13 The present work is part of a phytochemical investigation on aerial part of Algerian Artemisia judaica L. and concerns the isolation and identification of constituents of essential oil extracted from the aerial parts of the plant, grown in Algerian desert (In-Amenas), using GC and GC-MS techniques, with particular interest to comparison with oils produced by the same species grown in different geographical regions of the world. mixture was analysed under the same operative conditions on DB-1 column and the sample indices were calculated following Van den Dool and Kratz.…”
