| Abstract:
Supercritical CO2 extraction of Tagetes minuta L. oil was performed at P = 80 bar and T = 40°C using a semicontinuous extraction procedure and a two-stage separation technique. The co-extracted waxes were precipitated in the first separator at P = 80 bar and T = -15°C. The oil was isolated in the second separator operated at P = 15 bar and T = 20°C. The yield was 0,91% by weight after 840 min. Limonene (15,1%), cis-Ocimene (19,3%), Dihydrotagetone (5,2%), cis-Ocimenone (13,3%) and trans-Anetol (9,9%) were the main components identified in the extract obtained at 60 min; trans-Anetol was identified in the hydrodistilled oil, too. This compound has not been found in this kind of plant in previous publications. | |
