Thomson Flowers by Response Surface Method JF - KIMIKA JA - KIMIKA VL - 23 IS - 1 SE - Research Articles DO - 10.26534/kimika.v23i1.9-16 UR - https://kimika.pfcs.org.ph/index.php/kimika/article/view/7 SP - 9-16 AB - 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. ER -
