Analysis of Chemical Components and Antibacterial Activity in Essential Oil of Lantana Flowers (Lantana Camara L)

Abstract

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%.
