摘要：

The present research work describes the chemical composition and antimicrobial activity of the essential oils of the Lavandula hybrida L., Cymbopogon flexuosus L., Malaleuca alternifolia L. The essential oils were analyzed by gas chromatographic-mass spectrometric (GC-MS) analysis. Linalol (34.09%) and bergamiol (39.26%) were the main compounds of Lavandula hybrida L. essential oils; terpineol (45.77%) and terpinene (19.46%) of Malaleuca alternifolia L.; neral (33,92%) and geranial (43.76%) of Cymbopogon flexuosus L. This study used Escherichia coli, DSM-No. 10232 and Aspergillus niger DSM-No. 1957. The antimicrobial activity of the essential oils was evaluated using the agar diffusion method. The essential oils exhibited antimicrobial activity to varying degrees against the tested strains. This study indicated, that the essential oils of Lavandula hybrida L., Cymbopogon flexuosus L., Malaleuca alternifolia L. possesses antimicrobial activities in vitro against tested microorganisms. Namely best activity show Cymbopogon flexuosus L., against Aspergillus niger DSM-No. 1957. inhibition halos 14.4 +/- 2.5 mm, Escherichia coli DSM-No. 10232 inhibition halos 13.1 +/- 2.5mm.
