Comparative study of the chemical composition of the essential oil of origanum compactum from the seven regions of Morocco and their antimicrobial activity

Abstract

The aim of this work is to determine the chemical composition of the essential oil of Origanum compactum, from the region of Meknes (Morocco), and their antimicrobial effect, and on the other hand, to carry out a comparison between the chemical composition of this essential oil with the six regions of Morocco: Larache, Chefchaouen, Al Hoceima, Tetouan, Taounate and Rabat. The essential oils of Origanum compactum thus obtained were analyzed and identified by gas chromatography coupled with mass spectrometry (GC/MS). To determine the similarities and dissimilarities between the chemical compositions of the essential oil of Origanum compactum from the Meknes region with the other six regions of Morocco, we performed the principal component analysis (ACP). Regarding antimicrobial activity, the essential oils of Origanum compactum have shown significant inhibitory activity against the bacteria and molds studied.
