Description
Summary:The essential oil (EO) from the aerial parts of Lepechinia radula Benth Epling (Lamiaceae) from Ecuador was obtained by hydrodistillation. The chemical composition was determined by gas chromatography/mass spectrometry (GC/MS) and gas chromatography/flame ionization detection (GC/FID) analysis. Thirty-four compounds accounting to 93.4% of the total oil were identified. The main constituents of the essential oil were ?-3-carene (19.9%), ?-pinene (17.0%), (E)-?-caryophyllene (9.7%) and (E-E)-?-farnesene (9.4%). In order to determine antimicrobial activity of the essential oils, broth microdilution method was used. The essential oil of L. radula possessed strong antifungal activity against Trichophyton rubrum (ATCC� 28188) and Trichophyton mentagrophytes (ATCC� 28185).
