Composition and antimicrobial activity of essential oil and hexane-ether extract of Tanacetum santolinoides (DC.) Feinbr. and Fertig

The essential oil of the aerial parts of Tanacetum santolinoides was analyzed by capillary GLC and GLC-MS. Altogether 30 components were identified. The main constituents were thymol (18\%), traps-thujone (17.5\%), traps-chrysanthenyl acetate (13.2\%), cis-chrysanthenyl acetate (9.2\%), umbellulone (9.7\%) and 1,8-cineole (4.7\%). Similar essential oil pattern in addition to palmitic acid methyl ester, palmitic acid, stigmasterol, sitosterol and two flavonoidal aglycons were found in the n-hexane-ether extract. The oil showed strong in vitro activity against E. coli, Bacillus subtilis and Candida albicans.
