The essential oil of Cytisus triflorus L'Her., a Mediterranean species was obtained by steam distillation and identified by GC and GC-MS. 61 compounds were determined. The oxygenated terpenoidic components constituted the most important fraction (64%) followed by the fatty acids (8.2%) and the hydrocarbonated fractions (10.7%).

The essential oil of Thymus numidicus Poiret an endemic Algerian species was obtained by steam distillation and identified by GC and GC-MS. 48 components were determined. The oxygenated terpenoidic components constituted the most important fraction (71.7% ) while the non oxygenated fraction represented 26.2%. The major components were thymol ( 54.1%) followed by p-cymene (15,3%), linalool (5.4%) , carvacrol (3.8%), thymoquinone (3.7%) , α - pinene (2%), thymol methylether ( 1.7%) and β-caryophyllene (1.8%). Our result differ slightly from the few previous studies on this species and showed a relatively high proportion of p-cymene 15.3%) , α-pinene ( 2%) and hydrocarbonated sesquiterpenic fraction (4.6%) in comparison with the other samples studied previously.

The essential oil of the aerial parts of Pituranthos battandieri Maire (Apiaceae), synonym: Deverra battandieri (Maire) Chrtek., was obtained by steam distillation and analyzed by GC and GC-MS. 64 components were identified constituting 94.7% of the oil. Among the identified compounds, monoterpenes represented 77.4% among which 15.3% were oxygenated.The sesquiterpene fractions represented 16.5% among which 3.1% were oxygenated. The major constituents were myrcene (8.9%), α-phellandrene (17.5%), α-terpinene (14%), o-cymene (11.6%), β-phellandrene (3.5%), cis-linalool oxide (furanoid) (5.9%) and trans-β-caryophyllene (3.4%). This is the first report on the study of the chemical composition of the essential oil of this species. © 2016, International Journal of Pharmacognosy and Phytochemical Research.

The essential oils obtained by steam distillation of aerial parts of Santolina africana Jord. & Fourr. an endemic species to North Africa and Santolina chamaecyparissus L. growing in the East of Algeria were analyzed by GC and GC-MS. The main components of S. africana were β-pinene (12.78 %), 1,8-cineol (10.02 %), myrcene (6.94 %), curcumene (7.96 %), spathulenol (5.96 %) and β-eudesmol (14.58 %). These results were slightly different from a previous study which reported from the same species: terpinen-4-ol (44 %), borneol (6.73 %), camphor (15.11 %) and α-terpineol (11.31 %). Our results concerning S. chamaecyparissus showed as main components: thujene (2.46 %), camphene (6.84 %), myrcene (6.44 %), 1,8-cineol (11.22 %), terpinen-4-ol (4.93 %), spathulenol (7.59 %) and β-eudesmol (3.76 %). © 2015 Har Krishan Bhalla & Sons.
