Composition, enantiomeric distribution, and antimicrobial activity of Tanacetum argenteum subsp. flabellifolium essential oil.

摘要

Tanacetum argenteum (Lam.) Willd. subsp. flabellifolium (Boiss. & Heldr.) Grierson of Asteraceae is an endemic species in Turkey. Hydrodistillation of aerial parts using a Clevenger apparatus yielded an essential oil, which was subsequently analyzed by gas chromatography-mass spectroscopy (GC-MS). alpha-Pinene (29%), (E)-sesquilavandulol (16%), and camphor (14%) were found as main constituents. Enantiomeric distribution of the monoterpenes alpha-pinene and camphor was determined on a fused silica Lipodex E capillary column using a multidimensional gas chromatography-mass spectroscopy (MDGC-MS) system, (-)-alpha-pinene (86%), (+)-alpha-pinene (14%), and (-)-camphor (100%) enantiomeric distributions were found in the oil. Furthermore, antimicrobial activity of the oil was carried out using a micro-dilution assay against human pathogenic bacteria and the yeast Candida albicans resulting in moderate inhibitory concentrations (MIC=125 microg/mL).
