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 Hoceïma, 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.

Exploring the phytoconstituents, antimicrobial potency, and cytotoxic effects of essential oil from Origanum punonense from Palestine

“…EO yield of O. majorana varied from 0.04 to 0.09% during the full-flowering stage in Tunisia [ 26 ]. O. compactum average yield was about 3.62% from the region of Meknes [ 27 ].…”

“…It was suggested that carvacrol, a phenolic compound, possesses high levels of antimicrobial activity. While EOs from other Origanum species showed to possess high levels of antimicrobial activity, the EO inhibited the growth of all of the tested microbial strains [ 27 ].…”

GC/MS Profiling, In Vitro Antidiabetic Efficacy of Origanum compactum Benth. Essential Oil and In Silico Molecular Docking of Its Major Bioactive Compounds

“…As evidenced in several works, carvacrol and thymol as well as their biosynthetic precursors, such as cymene and γ-terpinene, represent a major part of total oil components (more than 70%) [34,36,37]. Moreover, β-caryophyllene and caryophyllene oxide were also observed in significant amounts [25,38,39]. Therefore, the chemical composition may be related to biosynthetic pathways, promoting the overexpression of some components and blocking the synthesis of others [40,41].…”
