This study examined the use of supercritical carbon dioxide (SC-CO 2) in the extraction of triglycerides from de-shelled Aquilaria crassna seeds. A central composite response surface methodology was employed to evaluate the effects of pressure, temperature and solvent-to-solid ratio (SSR) on total yield (TY), concentration of triglycerides ( CTG) and recovery of triglycerides ( RTG). For this experimental design, pressures that ranged from 250 to 350 bar, temperatures that ranged from 313 to 333 K and SSR that ranged from 80 to 120 were investigated for the SC-CO 2 extractions of 15 g of powdered de-shelled A. crassna seeds at a CO 2 flow rate of 25 mL/min under the supercritical phase. The values of TY, CTG and RTG achieved were 36.89%, 709.5 mg/g and 95.4%, respectively, under the conditions of a pressure of 340 bar, a temperature of 333 K and an SSR of 115 obtained from the quadratic fitting models.
