The air-dried leaves of Moroccan Argania spinosa were subjected to hydrodistillation (HD), to microwave (M) extraction and to supercritical fluid extraction (SFE) using CO . To the best of our knowledge, it is the first time that we report the microwave (M) and supercritical fluid extraction (SFE) for Argania spinosa. The essential oils obtained were analysed by GC and GC-MS. The main component for HD and SFE essential oils was cubenol (35.7-42.1 %), while the 1-epi-cubenol (21.8 %) dominated M essential oils. A total of 57 compounds, amounting 95 % of the oil, were identified. In addition, thirty six components of our A. spinosa essential leaf oil have not been previously described in the Argania spinosa essential oil in the literature.
