Drosanthe) grown in Turkey were analyzed by GC and GC-MS. Forty-eight compounds were identified in the essential oils of var. capitatum with alpha-pinene (20.3 %), caryophyllene oxide (11.8 %), hexadecanoic acid (8.9 %), beta-caryophyllene (6.5 %) and undecane (3.8 %) as main constituents. Thirty-eight components were identified in the oil of var. luteum with camphor (15.3 %), germacrene D (10.5 %), beta-myrcene (7.4 %), caryophyllene oxide (6.5 %) and beta-cububene (6.3 %), as the abundant components. More quantitative and qualitative differences were determined between two varieties of H. capitatum essential oils. The results were discussed in means of renewable resources and chemotaxonomy.</dc:description><dc:publisher>TAYLOR &amp; FRANCIS LTD</dc:publisher><dc:date>2011-01</dc:date><dc:type>Article</dc:type><dc:identifier>https://rdlopen.rawdatalibrary.net/r/munzur/3955</dc:identifier><dc:identifier>https://doi.org/10.1080/0972060x.2011.10643908</dc:identifier><dc:identifier>0972-060X</dc:identifier><dc:language>en</dc:language><dc:relation>JOURNAL OF ESSENTIAL OIL BEARING PLANTS</dc:relation><dc:rights>info:eu-repo/semantics/openAccess</dc:rights><dc:type>info:eu-repo/semantics/article</dc:type><dc:identifier>https://munzur-rdlopen.rawdatalibrary.net/tr/items/munzur/3955</dc:identifier></oai_dc:dc></metadata></record></GetRecord></OAI-PMH>
