The results show that the highest yield was 38.8 g oil/100 g sample obtained under extraction temperature of 60 C, pressure 41.4 MPa using particle size of 60.5 mm. Soxhlet extraction yields 34 g oil/100 g sample for 6 h of extraction time. The GCTOFMS shows that the supercritical
extracts exhibited significantly higher aromatic ether group comparable to those obtained by
soxhlet.
