Abstract

The fruits of endemic Prangos uechtritzii Boiss. & Hausskn. (Umbelliferae) were subjected to hydrodistillation and microdistillation. The resulting volatiles were investigated by GC-MS to determine the composition of the essential oils. 109 compounds representing 86.7 % and thirty-two compounds representing 90.0 % were identified and isolated by two different techniques, respectively. Column chromatography of the essential oil yielded a new bisabolene ether (7-epi-1,2-dehydrosesquicineole), which was characterized by spectral methods (GC-FTIR, 1D-, 2D NMR and HRESIMS).
