Antimicrobial Activity of the Essential Oil of an Endemic Plant in Morocco, Impatiens balsamina

Abstract

The purpose of this present work is to study the yield of the essential oil of an aromatic and endemic plant I. balsamina. Additionally, we intend to determine the chemical composition of the essential oil stemming from this species, as well as the determination of its antibacterial activity towards five microorganisms. Our samples result from Morocco, mainly from region Marrakech. 13 constituents were identified by chromatographic analysis (GC) in essential oil of this plant among which 3 are preponderant: β–thujone (66.75%), camphor (17.52%), and camphene (1.67%). The yield in essential oil of the Impatiens balsamina is in the order of 1,2% (mg/100 g). The essential oil of Impatiens balsamina showed a significant antimicrobial activity against all seven tested species of bacteria. To the best of our knowledge.
