It belongs to the Lamiaceae, and it characterized by many therapeutic properties: antiseptic, antinervous, analgesic). The volatile oils of Mentha spicata were extracted in all regions by hydrodistillation, and different values of yield ranging from 0.87% to 3% were recorded. The chemical analysis of these essential oils was carried out by the coupled gas chromatography with mass spectrometry CPG / MS , where the predominant compounds in all regions were Carvone(48.5-71.02%) and Limonene(5.85-20.7%), which recorded the highest rates compared to other essential oils, but differed quantitatively from the region to another.Arالمائي، الكروماتوغرافيا الغازية المدمجة بمطيافية الكتليةMentha spicata, Essential Oils, Hydrodistillation, The coupled CPG / MS .Master
