Description	Rhaponticum carthamoides (Willd.) Iljin (Asteraceae) is a perennial herbaceous plant originating in southern Siberia and Middle Asia and is currently cultivated mainly in Russia and East European countries as a medicinal plant. The roots and rhizomes of the plant have been traditionally used in folk Siberian medicine mainly as tonic, roborant and stimulant. A great number of constituents were isolated from this species, however, the composition of its essential oil remained unclear. Therefore, we have carried out a detailed analysis of Rhaponticum carthamoides root essential oil by GC, GC-MS, GC-FTIR techniques. The oil was isolated from the roots grown in the Czech republic. The distillation yielded 0.043% w/w of essential oil of dark yellow colour, resembling in its olfactometric properties the smell of fresh-cut roots. In total, 30 components were identified, accounting for 94.1% of total volatiles in the oil. New norsesquiterpene (22.6%), followed by known compounds aplotaxene (21.2%) and cyperen Rhaponticum carthamoides (Willd.)
