The chemical composition of leaves and flowers of Warionia saharae Bent. & Coss, have been examined by GC and GC-MS, the identified components constituting 95.3% and 84.1 % of the leaves and flowers oils respectively. The main constituents of leaves oil were linalool (27.7%), ?-eudesmol (25.7%), (E)-nerolidol (8.4%), geraniol 7.1%), ?-terpineol 5.5%), nerol 2.4%), eremoligenol 2.1%), ??-agarofurane (1.7%), 1,8-cineol (1.4%) and limonene 1.3%) while nerolidol 29.6%), ?-eudesmol 28.5%), farnesol 8.2%), 3.4%), ?-caryophyllene (3.1%), eremoligenol (2.5%), acorenone (2.1%) were established as the main components of the flowers. These results differ from the few previous studies reported on this species. Source

The chemical composition of the essential oil of Salvia verbenaca (L.) Briq. ssp. clandestina (L.) Pugsl. was analysed by GC and GC-MS, the identified components constituting 67.2% of the oil. thirty two components were identified. The main constituents were β-phellandrene (3.8%), α-copaene (10.4%), β-cubebene (2.7%), β-caryophyllene (3.8%), (E)-β-farnesene (3.5%), germacrene D (20.5%), bicyclogermacrene (2.2%), γ-cadinene (2.5%), δ-cadinene (2.6%), 1,10-di-epi-cubenol (2. 6%) and α-muurolol (2.1%).

The chemical composition of the essential oil of the endemic Saharian species Salvia verbenaca (L.) Briq. ssp. pseudo-jaminiana (Chev.) M. was analysed by GC and GC-MS, the identified components constituting 97.7% of the oil. Fifty three components were identified. The main constituents were β-caryophyllene (11.33%), muurola-3,5-diene (5.2%), cis muurola-4(14),5-diene (7.8%), bicyclogermacrene (10.9%), γ-cadinene (7.9%), spathulenol (3.0%), 1,10-di-epi-cubenol (20.9%) and epi-α-cadinol (11.6%). This is the first report on the chemical composition of the oil of Salvia verbenaca (L.) Briq. ssp. pseudojaminiana from Algeria. Source

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.

The chemical composition of the essential oil of Salvia aegyptiaca L. was analysed by GC and GC-MS, the identified components constituting 91.1% of the oil. Thirty five components were identified. The main constituents were limonene (3.2%), bornyl acetate (8.5%), β-bourbonene (2.9%), β-caryophyllene (10.2%), β-gurjunene (7.6%), selina-4,11-diene (9.7%), germacrene D (7.0%), bicyclogermacrene (2.3%), δ-cadinene (3.4%), germacrene B (4.8%), spatulenol (3.1%), β-caryophyllene oxide (6.2%) and α-cadinol (2.9%). This is the first report on the chemical composition of the oil of Salvia aegyptiaca from Algeria. Source
