Composition and Antimicrobial Activity of the Essential Oils of Tanacetum balsamita L. subsp balsamita and T. chiliophyllum (Fisch et Mey.) Schultz Bip. var. chiliophyllum (Asteraceae) from Turkey

Abstract

The chemical composition of the essential oils of dried aerial parts of Tanacetum balsamita subsp. balsamita and T.chiliophyllum var. chiliophyllum were analyzed by GC and GC-MS. Forty five and forty six components were identified representing 81.0 % and 84.4 % of the oils, respectively. Trans-chrysanthenol (22.3 %), chrysanthenyl acetate (19.7 %), linalool oxide (11.5 %), camphor (7.5 %), 1,8-cineole (2.7 %) were-found to be major components in T balsamita subsp. balsamita and camphor (28.5 %), 1,8-cineole (17.1 %), camphene (7.1 %), isobornyl propionate (5.4 %), carveol (4.5 %) and borneol (3.5 %) were also found as major constituents in T chiliophyllum var. chiliophyllum. In vitro antimicrobial activities of these oils and two antibiotics against Gram-positive and Gram-negative bacteria and two yeasts were also investigated. The results exhibited that the total oils and antibiotics possess moderate activities against all the tested microorganisms.
