Abstract The essential oils of Calligonum comosum subcultured at the South-Eastern of Tunisia (Bir Lahmar and Ghordab locations) and collected at the flowering and the fructification stages, were obtained by hydrodistillation and were analyzed by GC-FID and GC-MS in order to discern the differences and similarities between the investigated essential oils of this species. Sixty seven compounds representing 88.6495.60 % of the total essential oil were identified. The comparison of the essential oil components between the two locations of the subcultured C. comosum shows that there are 3 major common components identified at the two stages which were lauric acid, myristic acid and palmitic acid. Essential oil chemotype of C. comosum cultivated at Bir Lahmar location seems original since linoleic acid, palmitic and lauric acid were the most abundant compounds. While another new chemotype was evidenced from Ghordab location characterized by the dominance of linalool at the fructification stage and pentacosane at the flowering stage.
