N. N. Ab Rahman,M. N. Hassan,A. Omar,M. O. Ab Kadir 한국생약학회 1999 Natural Product Sciences Vol.5 No.2
Supercritical carbon dioxide was used as a solvent in the extraction of freeze-dried Pandanus odorus leaves. Analysis of the extract with GC-MS showed that Pandanus odorus leaves contain nutritional constituents such as α-tocopherol (Vitamin E) and squalene. The contents of α-tocopherol and squalene extracted from freeze-dried ground Pandanus odorus leaves at pressures ranging from 80 to 200 ㎏·㎝^(-2) and temperatures between 40 to 80℃ were 134∼300 ppm and 750-1,200 ppm respectively. The highest yield was obtained at 200 ㎏·㎝^(-2) and 40℃. Other major components identified were hexadecanoic acid, 9,12,15-octadecatrien-1-ol, campesterol, stigmasterol and β-sitosterol.
