CHEMICAL COMPOSITION AND ANTIBACTERIAL ACTIVITY OF ESSENTIAL OIL OF ZIZIPHORA HISPANICA L.

摘要

The aerial parts of Ziziphora hispanica L. species were collected on April 2011 from Boussaada localities in Algeria. The chemical compounds of the plant were isolated by hydrodistillation. A total of 28 constituents, representing more than 93.8% of the total oil, were identified by gas chromato- graph/mass spectrometry (GC/MS). The most presented compounds of the essential oil of Z. his- panica were Pulegone (78.6%), limonene, menthofuran, trans-iso-pulegone and piperitenone are rep- resented by low concentrations. The essential oil of aerial parts of Z. hispanica has a broad spectrum of antimicrobial activity. The sensitivity of bacteria and fungi tested with essential oil compounds was found to be very high.
