Prospects of Using Freons as Extractants of Curcuma Longa L. Root Essential Oil

the purpose of the present study was a comparative study of the ability of some freons to extract the essential oil of the roots of C. longa L. and to provide optimal conditions for its analysis. The dried, crushed roots of C. longa L. were used as raw materials (country of origin Uganda). Methoxynonafluorobutane (Novec 7100), fluoroketone and nhexane were used as extractants. Method of gas-liquid chromatography with mass detection was used. The most efficient extractant for ar-tumerone and curlone, which proved to be methoxynonafluorobutane (Novec 7100). The results of the studies indicate the prospects of using freons as extracting agents for the extraction of essential oil from the roots of C. longa L. The prospect consists in a more effective extracting ability of organofluorine solvents than n-hexane to increase the yield of both, the essential oil itself and the most pharmacologically relevant root components of C. longa L. ar-tumerone and curlone. Keywords—C. longa L. roots, ar-tumerone, curlone, methoxynonafluorobutane, fluoroketone, n-hexane.
