Abstract

This study describes the chemical composition and antimicrobial activity of essential oil of the of fruit of Kundmannia sicula L growing wild in jdiouya relizane region. This plant is very used in Algeria and widely used by local people for in traditional medicine for urinary tract infections and to treatement. We proposed to determine the physicochemical, organoleptic and chemical identification of these components. The chemical composition of the essential oil from Kundmannia sicula L. leaves was analyzed by GC/GC-MS and resulted in the identification of 5compounds. Other parameters such as refractive index, optical rotation; density, polarimetric deviation; freezing point and Solubility in ethanol are also measured .100% of the total peak areas were identified. The main constituents of the essential oil were the hydrocarbon and oxygen compounds are : 2-BUTENAL, 2-ETHYL97.44%, another important constituent were 2-Propanone, 1,1,3,3-tetrachloro- 2.45 % Other components were present with smaller percent..Isosafrole0.04% Octaverine0.03%, spathulenol 0.02%. The antimicrobial effect for germs causing nosocomial infection.

Keywords: Kundmannia sicula, leaves, Essential oil, GC/SM, antimicrobial activity.
