Antibacterial Activity and Chemical Composition of Essential Oil of Athamanta sicula L. (Apiaceae) from Algeria

Abstract

Essential oil extracted from fresh aerial parts of Athamanta sicula L. (syn. Tingara sicula) was analysed by gas phase chomatography coupled to mass spectrometry (GC-MS). The main constituents were: germacrene B (88.5%) and apiol (4.9%). Comparing with the tested bacteria, the growth of Escherichia coli and Klebsiella pneumoniae strains was more inhibited by the essential oil of A. sicula.
