## Abstract The extraction of aliphatic and aromatic hydrocarbons from New Albany Shale by supercritical carbon dioxide at different extraction temperatures is described. The main goal of this work was to determine the effect of the temperature on the extraction process (i.e. relative extraction ra

โฆ Synopsis
The rate of extraction of tnacylglycerols with supercntical carbon dioxide can be greatly enhanced by raising the pressure of the fluid to 600 bar, or higher, and its temperature to 60ยฐC, or higher. Both the amount of carbon dioxide and the time required for complete extraction are reduced at such high pressures and temperatures.

Supercritical carbon dioxide extraction was carried out in the temperature range 35 to 60ยฐC and from 10 to 30 MPa in order to obtain phytochemical components from several medicinal plants. These were nonacosan-10-ol (1) from the aerial parts of Ephedra sinica, โฃ-amyrin acetate (2) from the root bark
