Chemical composition and variability of the volatile components from inflorescences of <i>Cirsium</i> species
No full text<div><p>The present study aimed to investigate the chemical composition of the essential oils of inflorescences <i>Cirsium</i> spp. (Asteraceae) by GC/MS method. Essential oils were extracted from the inflorescences of <i>Cirsium pannonicum</i> (Link), <i>Cirsium ligulare</i> Boiss., <i>Cirsium heterophyllum</i> (L.) Hill., <i>Cirsium acaule</i> (L.) Scop., <i>Cirsium oleraceum</i> (L.) Scop., <i>Cirsium dissectum</i> (L.) Hill., <i>Cirsium decussatum</i> (Janka) and <i>Cirsium eriophorum</i> (L.) Scop., using the steam distillation method. A gas chromatography–mass spectrometry method was employed for the analysis of essential oils. Our study shows the differences in chemical composition of volatile oils in the inflorescences of <i>Cirsium</i> spp. The main components of the essential oil were ketones and aldehydes with a long carbon side-chain. Volatile oils also contained small amounts of terpenes: thymol, β-linalool, eugenol, carvacrol and fatty acids with odd number of carbon atoms–waxes. The compounds in the essential oils obtained from inflorescences <i>Cirsium</i> L. species have been identified for the first time.</p></div
