Pithecellobium Jiringan (Jack) Prain (P.Jiringan) merupakan salah satu daripada sumber tumbuhtumbuhan yang mengandungi komponen antioksidan. Tujuan kajian ini dijalankan adalah untuk mengkaji kesan-kesan parameter kaedah penyarian bendalir lampau genting dengan menggunkan karbon dioksida sebagai pelarut (SC-CO2) ke atas hasil minyak dan untuk mengukur kebolehlarutan minyak P.Jiringan didalam (SC-CO2) dan mengkorelasi data kebolehlarutan minyak P.Jiringan dengan model Chrastil dan del Valle & Aguilera. Kajian ini telah dijalankan pada suhu antara 40oC sehingga 70oC dan pada tekanan antara 27.58 MPa sehingga 44.82 MPa. Tempoh pengekstrakan adalah 60 minit. Penemuan hasil kajian ini menunjukkan bahawa hasil minyak meningkat dengan peningkatan tekanan dan peningkatan suhu. Pada keadaan suhu malar, kebolehlarutan minyak meningkat dengan peningkatan kepadatan CO2. Analisis keputusan menunjukkan bahawa data keterlarutan minyak P.Jiringan telah berjaya dipadankan dengan model Chrastil. Di samping itu, SC-CO2 memberikan hasil minyak tertinggi berbanding dengan ASE dan proses pengekstrakan Soxhlet. Kata kunci: Kebolehlarutan; Model Chrastil; penyarian bendalir lampau genting; Pithecellobium Jiringan (Jack) Prain 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-CO2) 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 40oC to 70oC 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 CO2 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-CO2 give the highest oil yields compared to accelerated solvent extraction (ASE) and soxhlet extraction process.
