ABSTRACT

NINONUEVO, MILADY ROXAS, College of Arts and Sciences, University of the Philippines Los Banos, October 1997. Application of Pectinases in the Extraction of Essential Oils from Ilang-ilanq Flowers (Cananga odorata).

Adviser: DR. TERESITA M. ESPINO

Enzymatic extraction of essential oils of Ilang-ilang (Cananga odorata) utilizing pectinase was conducted in this study. Several parameters to maximize the essential oil yield such as enzyme concentration, incubation time, buffer dilution ratio and incubation temperature were optimized. The effect of extracting solvents such as petroleum ether and ethanol was also investigated.

An essential oil yield of 0.93% was obtained using 0.5% pectinase diluted with 1:0.3 (w/v) buffer at room temperature after 24-hour incubation with petroleum ether as the extracting solvent while a 0.53% essential oil yield was recovered for the untreated sample.

Based on the physico-chemical analyses, the extracted essential oil from Hong-Hang flowers can be considered similar to that of an extra-grade oil while that of the untreated sample of lower quality essential oil.
