In this study the essential oil components aerial parts of Tanacetum heterotomum （Bornm.） Grierson, T. zahlbruckneri （Nab.） Griersson, T. densum （Lab.） Schultz Bip. subsp, amani Heywood and T. cadmeum （Boiss.）...In this study the essential oil components aerial parts of Tanacetum heterotomum （Bornm.） Grierson, T. zahlbruckneri （Nab.） Griersson, T. densum （Lab.） Schultz Bip. subsp, amani Heywood and T. cadmeum （Boiss.） Heywood subsp, orientale were examined by HS-SPME/GC-MS technique. Thirty six, thirty nine, forty and forty five constituents were determined representing 88.9%, 90.1%, 90.8% and 91.5% of the oil, respectively. The main compounds of studied Tanacetum L. taxa; borneol, α-pinene, 1,8-cineole, β-pinene, camphor, germacrene D, spathulenol are determined. Studied Tanacetum taxa showed congruency with the discription in Flora of Turkey as morphological properties; on the contrary essential oil composition were detected very quiet diverse infrageneric level. Chemotypes of Tanacetum L. taxa were reported as borneol, germacrene D, spathulenol, α-pinene, 1,8-cineole, β-pinene and camphor. The results obtained from this study were discussed in terms of chemotaxonomy and natural products.展开更多
