CHEMICAL COMPOSITION AND ANTIMICROBIAL ACTIVITY OF THE ESSENTIAL OILS OF FOUR VARIETIES OF LIPPIA MULTIFLORA IN BENIN

Objective: Present study involves the study of the chemical composition of the essential oils extracted from the leaves by gas chromatography and gas chromatography coupled with mass spectrometry of Lippia multiflora harvested in the regions of Kétou, Savalou, Bohicon and Mono and tested by the well diffusion method against pathogenic microorganisms.Methods: The essential oils studied are terpene compounds, aromatic compounds, aliphatic compounds and other natural substances. The inhibition zone diameters determined allowed us to evaluate their degree of germ sensitivity of the strains tested. Essential oils extracted from Lippia multiflora harvested in these areas have the most pronounced antimicrobial activity.Results: In total, the essential oils tested have different and specifically a degree of sensitivity against Staphylococcus aureus ATCC 25923, Escherichia coli ATCC 25922, Proteus mirabilis A24974, Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae and Pseudomonas aeruginosa except that harvested in the Savalou who does not have no degree of sensitivity on Pseudomonas aeruginosa.Conclusion: This work paves the way for food preservation with extracted natural substances and also the formulation of natural antimicrobials for this fact.
