Abstract :
Pithecellobium Jiringan (Jack) Prain (P.Jiringan) is one of the medicinal plant sources that consist of antioxidant compounds. The aim of this study was to investigate the effects of supercritical carbon dioxide (SC-CO_2) extraction parameters on oil yields and to measure the solubility of P.Jiringan oil in SC-CO2 and correlated the data with Chrastil and del Valle Aguilera models. The experimental were conducted at temperatures ranging from 40 ℃ to 70 ℃ and pressure from 27.58 MPa to 44.82 MPa. The extraction duration was 60 minutes. The result shows that the oil yields increase as the pressure and temperature increase. The solubility of oil increased as the density of CO_2 increased at constant temperature. An analysis of the results show that the solubility experimental data correlated with the Chrastil’s model was successfully matched. In addition, SC-CO_2 give the highest oil yields compared to accelerated solvent extraction (ASE) and soxhlet extraction process.
