The aim of this study was to determine the oil recovery from Swietenia macrophylla seeds and its solubility in Supercritical CO2 extraction process. Experimentally, the oil recovery from the seeds were conducted at 15-35 MPa and 40-60°C by Supercritical CO2 extraction process. Density-based models such as Chrastil and del Valle and Aguilera models were used to correlate the solubility data of Swietenia macrophylla seeds oil. The high oil recovery obtained at 35 MPa and 60°C was 6.609 mg oil/g CO2 while the lowest oil recovery was at 15 MPa and 40°C (0.810 mg oil/g CO2). Chrastil model provide the best correlation between experimental and calculated solubility data for oil recovery from Swietenia macrophylla seeds with lowest value of average absolute percent deviation (AAPD) which is 0.33% compared to del Valle and Aguilera model (0.39%).
