Cinnamaldehyde and eugenol were extracted by supercritical carbon dioxide. The results of cinnamaldehyde and eugenol recovery indicated that the data sufficiently fitted into a second-order polynomial model. The R-2 and adjusted R-2 turned out to be 95.26% and 91.11% for cinnamaldehyde and 97.93% and 96.12% for eugenol. The response surface methodology (RSM) modelling predicts the optimum operating conditions for cinnamaldehyde to be the pressure of 2.3 M Pa, temperature of 68.2 degrees C, flow rate of 1.8 ml/min and dynamic extraction time of 95.7 min with maximum recovery of 54.79 w/w%. The RSM modelling also predicts the eugenol maximum recovery of 38.42 w/w%, which was obtained at optimal operating conditions of 42.04 degrees C, 2.7 MPa, 2.3 ml/min and 118 min dynamic extraction time. Accuracy of modelling optimal cinnamaldehyde and eugenol recoveries were validated using triplicate experiments providing the average extraction recoveries of 54 +/- 1% and 38 +/- 1.5%, respectively.
