    Water distilled essential oil of aerial parts of Tanacetum cadineum (Boiss.) Heywood subsp. orientale Grierson (Asteraceae) was analyzed by GC and GC/MS methods. Ninety three compounds have been characterized representing 97.8% of the oil. 1,8-Cineole (1.8.9%), p-cymene (15.7%), terpinen-4-ol (14.8%), borneol (9.8%) and gamma-terpinene (3.5%) were found to be the major constituents of the oil. Antimicrobial activity of the oil was tested via micro-dilution broth method. Escherichia coli, Staphylococcus aureus, Enterobacter aerogenes, Salmonella typhimurium, Bacillus cereus, Staphylococcus epidemidis, Candida albicans were used as the test microorganisms.

    Composition and antimicrobial activity of the oils of Ferula szowitsiana DC. from Turkey
    (TAYLOR & FRANCIS INC, 2008) Oezek, Guelmira; Oezek, Temel; Iscan, Goekalp; Baser, K. Huesnue Can; Duran, Ahmet; Hammoglu, Ergin
    The essential oils from the leaves and steins of Ferula szowitsiana DC. (Umbelliferae) were separately obtained by hydrodistillation and then analyzed by GC and GC/MS methods. The oil yields were 0.4% and 0.05%, respectively. One-hundred and sixty-two compounds representing 99.5% and 99 compounds representing 94.4% were identified in the leaf oil and stem oil, respectively, with beta-eudesmol (32.0% and 29.5%, resp.), alpha-eudesmol (18.2% and 16.6%, resp.) and alpha-pinene (8.6% and 6.4%, resp.) as the major constituents. Antimicrobial activity of the leaf oil was tested via in-vitro microdilution broth technique. Escherichia coli, Pseudomonas aeruginosa, Proteus vulgaris, Salmonella typhimurium, Staphylococcus epidermidis, Methicillin-resistant Staphylococcus aureus, and Candida albicans were used as the test microorganisms.
