The essential oil composition of <i>Phlomis bovei</i> subsp. maroccana Maire, an endemic species of Morocco

<i>Phlomis</i> L. is a genus belonging to the Lamiaceae family, distributed in Macaronesia, the Mediterranean basin, Northeast Africa, Central Asia, and Western Himalaya. Plants of this genus are used against various diseases in the ethno-medicine of several countries and some of them are also utilised for culinary purposes. In the present study, the essential oil chemical composition of the aerial parts of <i>Phlomis bovei</i> subsp. <i>maroccana</i> Maire, an endemic species of Morocco, was analysed by GC-MS. No previous paper has been previously published on this taxon. Main constituents of the essential oil were sesquiterpene hydrocarbons (44.48%) with curcumene (11.20%), a very rare compound in <i>Phlomis</i> essential oils, <i>β</i>-himachalene (6.22%), and <i>β</i>-cedrene (3.81%) as principal metabolites. 1-hexadecanol (7.75%) and 1-octadecanol (5.32%) were the main constituents among the alcohols (19.66%). A comparison with all the other essential oils from <i>Phlomis</i> taxa has been carried out.
