The composition of extracts of Ferula soongarica Pall. ex Schult. from two regions of Kazakhstan, obtained by supercritical C02 extraction was investigated by GC/MS.
Keywords: Ferula soongarica, supercritical fluid extraction (SCFE), GC/MS.

Ferula soongarica Pall. ex Schult. is high plant spread in Central Asia. Phenolic and terpenoid esters were isolated before from roots of F. soongarica [1-3]. Composition of essential oils from China and Kazakhstan was investigated as well [4, 5], but it is necessary to note, that research of essential oil of F. soongarica obtained by C02 extraction method haven’t been investigated before.
Plant material. Plants were collected by authors in Arshaly district near Astana (A) and in Zhezkazgan botanic garden (B) (Kazakhstan Republic) and deposited in Zhezkazgan Botanic garden (Voucher code is 2009.15.05.01.02).
SCFE. Supercritical fluid extraction was done as described in [6]. We collected extracts within an hour. The yield of essential oil is from 3,22 to 2,5% for raw material A and B respectively. The obtained extracts were dissolved in 1 ml of ethanol, cooled overnight at -20 °C, filtered and analyzed by GC/MS.
GC/MS. Component composition of essential oil was analyzed by the method of GC/MS and was done as described in [6]. Composition of CO2 extract of F. soongarica given in the table.
