The leaf oils of four Cypress species growing in Algeria were examined by GC and GC/MS. In total 76 constituents were identified, from which 49, 46, 48 and 54 compounds were found in the oils of Cupressus glabra Sudw., C. arizonica Greene, C. sempervirens L. and C. dupreziana Camus. The main components of the oils were: C. glabra: terpinen-4-ol (10.5%) and umbellulone (27.4%); C. arizonica: alpha-pinene (10.5%) and umbellulone (37.3%); C. sempervirens: alpha-pinene (2.8-44.9%), delta-3-carene (3.1-10.6%) and alpha-terpinyl acetate (5.5-12.0%) and C. dupreziana: alpha-pinene (36.4%) and delta-3-carene (33.8%)
