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

Abstract

The essential oil of Artemisia judaica L. growing spontaneously in In-Amenas in southern Algeria (desert region) was investigated by GC and GC-MS. Essential oil was isolated from the aerial parts by hydrodistillation in 0.70% yield. Sixty-two components were identified, amounting to 95.1% of the oil. The main components were piperitone (61.9%), terpinen-4-ol (4.6%) and bornyl acetate (3.0%). Isolation of the Essential OilThe essential oil of the air-dried aerial parts of A. judaica L. was obtained by hydrodistillation for 3 h using a Clevenger-type apparatus. The essential oil was dried over anhydrous sodium sulphate and stored in a sealed vial at 4°C until analysis. GC AnalysisGC analysis was performed on a Chrompack CP 9002 chromatograph, using a fused silica capillary column with DB-1 stationary phase. The various parameters fixed for the DB-1 column were: 30 m × 0.32 mm, 0.25 µm film thickness; column temperature programme, 50°C for 3 min, rising at 2°C/min to 260°C, then held for 5 min; FID-detector heaters, 280°C; injector heaters, 250°C; carrier gas, nitrogen at a flow rate of 1 ml/min; split ratio, 1:50; injection volume, 0.2 µl. In order to determine retention indices (RI), a series of n-alkanes (C 5 -C 28 )

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.…”

“…The essential oil of Jordan A. judaica was obtained with a yield of 1.62% r 0.129 that was higher than the yields obtained with aerial parts of A. judaica grown in Egypt, Algeria and Libya, which were 1.4% r 0.05 (El-Massry et al, 2002), 0.70% (Dob and Chelghoum, 2006) and 0.62% (Janaćković et al, 2015), respectively. These differences detected in the essential oil yields of A.…”

“…Libya and Egypt, and in other countries of the Middle East, including Sinai-Egypt, Israel, and Saudi Arabia (Van Wyk & Wink, 2004;Friedjung, 2010). Artemisia judaica L. is a perennial, bushy herbs, strongly aromatic, with woody bases and strong spreading branches, covered by woolly hairs, leaves grayish, dissected, short, crowded, heads are rounded, crowded and made of tubular florets (Dob & Chelghoum, 2006;Friedjung, 2010).…”

Evaluation of in vitro shoots of Artemisia judaica for allelopathic potential

“…A number of volatile chemical constituents from the aerial parts of A. judaica have been identified. The major compounds were identified as piperitone and cinnamate derivatives (ElMassry et al 2002;Dob and Chelghoum 2006). However, whether these compounds function as allelochemicals is still unknown, and to date, there is little information available on the allelopathic potential of A. judaica.…”

Chemical Composition of the Essential Oil ofJuniperus phoeniceaL. from Algeria

“…Consequently, in continuation with our work on the characterization of aromatic and medicinal plants from Algeria (31)(32)(33), the authors now report the chemical composition of the leaf oil of J. phoenicea collected from Djelfa (steppe region) city of Algeria.…”
