Sažetak
Most plants produce antimicrobial secondary metabolites, either as part of their normal program of grow and development or in response to pathogen attack or stress. Research on and identification of active plant metabolites is important in the search for new antibiotic compounds. The aim of this study was to investigate chemical composition and in vitro antimicrobial activity of Achillea clavennae L. essential oil. The volatile constituents of A. clavennae (Asteraceae), rare plant of the Europe, has been analysed using GC/MS. Plant material was collected in June 2001 from the Velebit Mountains (Dalmatia-Croatia). Dried aerial parts of A. clavennae, were found to contain 0.7% of essential oil. Twenty-five components making up 81.6% of the oil were characterized with camphor (29.5%), myrcene (5.5%), 1.8-cineole (5.3%), β ; -caryophyllene (5.1%), linalool (4.9%) as major constituents. The screening of the antimicrobial activity of essential oil was conducted by a disc diffusion test against six Gram-positive, seven Gram-negative bacteria and four fungal organisms. The activity was more pronounced against Gram-negative and fungal organisms than Gram-positive bacteria. Maximum activity was observed against Klebsiella pneumoniae. The essential oil of A. clavennae also exhibited the strong activity against Gram-negative Haemophilus influenzae and Pseudomonas aeruginosa. The antibacterial activity of A. clavennae oil appears interesting to be considered for practical uses in respiratory tract infections.
