Optimization of Supercritical Carbon Dioxide Extraction of Essential Oils in Philippine Cananga odorata Hook Fil et. Thomson Flowers by Response Surface Method

Sheeva M. Yahcob, Roberto M. Malaluan


Essential oil was extracted from the flowers of Philippine Cananga odorata var. genuina grown in Pala-o, Iligan City by supercritical carbon dioxide (SC-CO2). A statistical experimental design, first order 2^3 factorial, was used to investigate the effects of three independent variables (pressure, temperature, and flow rate of CO2) on % oil yield (w/w), & linalool (v/v) and % benzyl benzoate (v/v) on the extracted oil. An optimum oil yield (9.21 % w/w) was obtained under the following SC-CO2 extraction operating conditions (98.61 bar, 39.58 deg C, 2.99 mL/min). Gas chromatography was performed on the ilang-ilang oil extracted by SC-CO2 extraction, laboratory, and commercial scale hydrosteam distillation. Degradation products were observed in the hydrosteam distillated sample.
