<![CDATA[The purpose of this study was to evaluate the essential oil composition as well as antibacterial activities of essential oil of Lantana camara L flowers against four bacterial strains. Essential oil of Lantana camara L flowers was obtained by hydrodistillation method using Sthal and analyzed by GC-MS. The antibacterial activities of essential oil were tested by using disk diffusion method against four bacterial strains. Results showed 72 compounds for Lantana flowers essential oil, of which caryophyllene (10,87%), davanone (9.84%), a-humulene (7.59%), a-curcumene (3.35%), germacrene D (3.09%), calarene (2.42%), a-muurolene (2.27%), p-cymene (1.79%), 1,8 cineole (1.59%) , δ-cadinene (1.59%), a-copaene (1.12%), nerolidol B (1%) and ß-ocimene (0.54%) were detected as major components. Antibacterial activity assay of Lantana camara L flowers essential oil was examined against four bacterial strains including Gram (+and-) by using disk diffusion agar method. All the tested Gram (+and-) bacterial strains displayed slight to moderate antibacterial activity (7 – 10 mm) against all concentrations of essential oil. The essential oil of Lantana camara L flowers showed remarkable antibacterial activity with inhibition in concentrations of 10% and 20% against the phatogen bacterias Basillus subtilis (9.6 mm; 10.8 mm), Propionibacterium acnes ( 7.6 mm; 8.7 mm), Eschechia coli ( 8.4 mm ; 9.6 mm) and Pseudomonas aeruginosa ( 8.3 mm ; 9.3 mm) showed from zone of inhibition that was formed, zone of inhibition in concentration 20% was bigger than concentration 10%.]]>
