✦ Synopsis

In this work the extraction of grape seed oil by means of liquid and supercritical carbon dioxide as solvent is described. The operating conditions to determine the maximum extraction yield were studied. The efficiency of supercritical fluid extraction (WE) was similar to that obtained by conventional liquid extraction, but the quality of the supercritically extracted oil was higher, equivalent to a degununed, liquidextracted oil. It is considered that SFE is competitive with conventional liquid extraction, because the solvent distillation and oil refining stages can be omitted.

Supercritical carbon dioxide extraction was carried out in the temperature range 35 to 60°C 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, ␣-amyrin acetate (2) from the root bark
