Extraction of α-tocopherol from palm leaflets by supercritical carbon dioxide (SCCO2) was attempted. The yields of SCCO2 extracts and α-tocopherol from dry samples were higher than those obtained from wet samples. It was also found that using dry samples at 200kg/cm2 and 40ºC, it is possible to produce an extract containing more than 9% of α-tocopherol with a yield greater than 90%.
