| Summary: | Mahkota dewa (Phaleria macrocarpa) which belongs to Thymelaeaceae family
is being used as medicinal plant in tropical countries especially in Malaysia and
Indonesia. Almost all parts of this plant except seed have importance in traditional
medicine. The seed contains high amount of oil. In this study, solvent extraction and
supercritical fluid extraction using carbon dioxide were used to extract oil from the
Mahkota dewa seed. The effecting parameters of supercritical carbon dioxide extraction
were optimized for obtaining higher yield of oil by response surface methodology (RSM)
with central composite design (CCD). By solvent extraction, more than 55g per 100g of
dry weight of seed was obtained whereas at optimum condition of supercritical fluid
extraction, the oil yield was around 53g per 100g of dry weight of seed. However, the
purified oil was extracted by SFE that is of organic residues free. The triglycerides in
terms of fatty acid constituents of the extracted oil were analyzed by gas chromatographymass
spectroscopy (GC-MS). The extracted oil found to have 73% unsaturated fatty acids
and 26% saturated fatty acids. Polyunsaturated fatty acids were in the percentage of
36.25%. Thus, the supercritical CO2 extracted Mahkota dewa (P. macrocarpa) seed oil of
could be claimed as high quality and toxic free food and pharmaceutical grade oil. |
