Abstract
The essential oil of Lavandula stoechas. L. growing spontaneously in Algeria was investigated by gas chromatography (GC) and gas chromatography/mass spectrometry (GC/MS) for the first time. The oil was isolated from the aerial parts of the plant (leaves and flowers) by distillation in a yield of 1.1%. Fifty-four components amounting to ca.. 73% of the oil were identified, the major component being fenchone (31.6%). The other significant constituents were camphor (22.4%), p.-cymene (6.5%), lavandulyl acetate (3.0%), and α-pinene (1.0%). Our results show that the oil consists mainly of oxygenated monoterpenes (62.0%). A comparison with oils from other Lavandula stoechas. from other countries reported in literature shows qualitative and quantitative differences.
