Laurus nobilisL. and the Study of its Biological Activityin vitro

Abstract

This work focuses on the study of the antimicrobial activity of the essential oil (EO) ofLaurus nobilisL. plant. The extraction of essential oil of the aerial parts ofLaurus nobilisL. was conducted by the hydrodistillation method. Antimicrobial activity test was performed on five bacterial strains (Klebsiella pneumoniae,Escherichia coli,Proteus mirabilis,Enterobacter cloacae,Enterococcus faecalis). The results showed thatLaurus nobilisEO has moderate antibacterial activity. In addition, the antifungal activity of theLaurus nobilisL. EO was analyzed; the direct contact method was performed onFusarium sporotrichioidesin different EO concentrations (0.05, 0.25, and 0.5% of EO). The results showed that this essential oil has significant antifungal activity on this strain; there was a 100% growth inhibition at a concentration of 0.5%.
