Schultz Bip. subsp. amani Heywood is an endemic plant of the Southeastern Anatolian, Turkey. Air-dried aerial parts of the plants were submitted to hydrodistillation, for 3 hours, using a Clevenger-type apparatus. Cultivated and wild Thymbra spicata var. spicata, Thmybra sintenisii Bornm. & Aznav. and Tanacetum densum subsp. amani species were compared for their essential oil constituents using GC/MS analysis. The results showed that the major constituents of essential oil of both Thymbra species were carvacrol, gamma-terpinene, p-cymene, beta-caryophyllene, myrcene and alpha-phellandrene. Essential oil of cultivated T. spicata contained lower carvacrol percentage (67.91%) compared to the carvacrol percentage of cultivated species (72.56%). Conversely a-pinene percentage of cultivated T. sintenisii was higher compared to wild forms. P-cymene was found second major constituent in the essential oil T. sintenisii. Tanacetum oil was pale greenish and had a pleasant odour, with a yield of 0.1% (v/w) for wild form and 0.15% for cultivated form. Twenty-three components representing 84.53-93.41% of the oil were characterized, of which bisabolone oxide (25.62%), carvacrol (26.73%), isoborneol (10.07%), borneol (14.05%), beta-panasinsene (8.95%), eucalyptol (10.13%) and camphor (4.71%) were the main compounds.eninfo:eu-repo/semantics/closedAccessThymbra SpicataT.
