Abstract

Essential oils obtained by hydrodistillation from leaves of Pistacia lentiscus L. from four regions of Nord-Est Algeria (Bejaia, Jijel, Skikda and El-Taref) were analysed by GC and GC-MS. A total of 132 compounds accounting for 69,41-99,97% of the total EO were identified. Two main essential oil profiles have been distinguished according the rate of monoterpene/sesquiterpene. The samples collected from Bejaia and Skikda respectively was found to be rich in monoterpene hydrocarbons (35-56,39%), whereas sesquiterpene hydrocarbons was found to be rich in the samples collected from Jijel and El-Taref respectively (44- 53,19%). The results clearly indicate the appearance of four chemotypes which are currently described. The first contains high proportions of α-pinene (12.12) in Bejaia oil. The second contains a high proportions of caryophyllene (20.87%) and α-pinene (17,83%) in Jijel oil. The third contains a high proportion of D-limonene in Skikda oil (31.42%). The last revealed that β-cubebene (18.92%) and caryophyllene (17.58%) were the main constituents of El-Taref oil, this particular composition is reported for the first time in the P. lentiscus species. A comparison with oils from P. lentiscus of diverse regions of Algeria and other countries of mediterranean region reported in literature shows both quantitative and qualitative differences.
