Effect of pressure on supercritical carbon dioxide extraction from various seeds was studied. Three kinds of seeds (rosehip, loquat and physic nut) were used as materials. Extraction was conducted at constant temperature (40, 60 and 80°C), at CO 2 flow rate of 3ml/min and at various pressures (15–9MPa). Recovery of extract was compared with soxhlet extraction recovery using hexane as solvent...
