Extraction and Separation on Fragrance of the Rosa damascene Mill. By supercritical Carbon Dioxide Extraction

Abstract

Extraction and separation on fragrance of the Rosa damascene Mill. By supercritical carbon dioxide extraction was conducted at Oil Plant Research Building,Departmant of Agriculture during January – March 2000-2003. The experiment design was 3² factorial in RCB with 3 replications. First factor was levels of CO2temperature: 40, 45 and 50๐C. Second factor was levels of CO2density: 0.30, 0.50 and 0.70 g/ml and extraction time was fixed at 60 min. Determined the component of fragrance by gas chromatograph. The study showed that phenyl ethyl alcohol (PEA) was the main component of fragrance of the Rosa damascene Mill. The processing condition of CO2 at 50๐C and 0.70 g/ml (151 bar) gave the highest yield (97.48% by mg PEA/100 g test sample).
