Norsesquiterpene hydrocarbon, chemical composition and antimicrobial activity of Rhaponticum carthamoides root essential oil

Original language description

A detailed analysis of Rhaponticum carthamoides (Willd.) Iljin root essential oil was carried out by GC, GC?MS and GC?FTIR techniques. In total, 30 components were identified. A new norsesquiterpene 13-norcypera-1(5),11(12)-diene (22.6%), followed by aplotaxene (21.2%) and cyperene (17.9%), were isolated and their structures confirmed by 1D and 2D-NMR spectra (COSY, ROESY, HSQC, HMBC and INADEQUATE). The oil exhibited antimicrobial activity against 5 of 9 strains of bacteria. Minimum inhibitory concentrations ranged between 32 and 256 ?g/ml.

Czech description

Byla provedena detailní analýza silice z kořenů Rhaponticum carthamoides (Willd.) Iljin pomocí technik GC, GC?MS a GC?FTIR. Bylo identifikováno 30 látek. Hlavními složkami byly nový norseskviterpen 13-norcypera-1(5),11(12)-dien (22.6%), aplotaxen (21.2%)a cyperen (17.9%), jejichž struktury byly potvrzeny 1D a 2D-NMR spectry (COSY, ROESY, HSQC, HMBC a INADEQUATE). Silice vykazovala antimikrobiální aktivitu v řádu 32-256 ?g/ml proti 5 z 9 testovaných mikroorganismů.
