Composition of helichrysum thianschanicum regel essential oil from Pamir (Tajikistan)

Abstract

Helichrysum thianschanicum Regel was collected from Khorugh town of Kuhistoni Badakhshon Autonomous Province of Tajikistan. The essential oil was obtained by hydrodistillation and analyzed by gas chromatography-mass spectrometry. A total of 67 compounds were identified representing 88.4% of the total essential oil composition. The major components of H. Thianschanicum essential oil were (E)-1-(6,10-dimethylundec-5-en-2-yl)-4-methylbenzene (pentylcurcumene) (21.6%), ß-selinene (6.4%), d-selinene (3.8%), (2E,6E)-farnesol (3.3%), nerol (4.1%) and neryl decanoate (4.2%). To our best knowledge, no previous studies have been reported on the chemical composition of the essential oil of H. Thianschanicum.
