The essential oil and the volatile compounds of Salvia aucheri Boiss. var. mesatlantica Maire were analyzed by gas chromatography (GC) and GC-mass spectrometry (GC-MS). The volatile compounds were detected using headspace-solid phase microextraction (HS-SPME) under optimized parameters. A comparative qualitative and quantitative study on the composition of the oils was carried out. For this, 38 compounds, constituting 95.40% of the oil, were identified in the essential oil by hydrodistillation (HD), and 32 compounds, representing 93% of the oil, were characterized by HS-SPME. The major components identified are camphor (49.80%, 51.80%), 1,8-cineole (9.50%, 9.40%), viridiflorol (8.80%, 1.40%), camphene (7.80%, 10.60%), α-pinene (2.90%, 4.50%), and p-cymene (1.50%, 2.40%) of essential oil and volatile compounds detected in HS-SPME, respectively. Quantitative but not qualitative differences have been found in the chemical composition of both analyzed samples depending on the extraction method. For these reasons, HS-SPME can be considered as an alternative technique for isolating volatiles from aromatic plants.
