Item Extracción de tocoferoles y tocotrienoles de los ácidos grasos destilados de palma utilizando solventes eutécticos profundos(Universidad Santiago de Cali, 2024) Escobar Maca, Maicol Estefano; Tusso Pinzón, Ricardo Andrés (Director); Cadena Rayo, Milton Rene (Director)In this study, the extraction of vitamin E (tocopherols and tocotrienols) from distilled palm fatty acids (DPFA) was investigated using deep eutectic solvents (DESs). Two types of DES were used: choline chloride–p-cresol (DES1) and choline chloride–acetic acid (DES-2), prepared at 60 ºC with constant stirring and in molar ratios of 1:1, 1:2 and 1:3 for each case. The DES and DPFA mixtures were centrifuged, and the DES phases were decanted. They were then mixed with 10 mL of hexane and centrifuged again to separate the hexane phase from the DES phase. The hexane phase was analyzed by high-performance liquid chromatography with a UV detector at 290 nm (HPLC-UV), together with the DES and DPFA phases. The highest extraction percentage, 78.95%, was obtained with DES-1 in a molar ratio of 1:3, while the highest purity, 35.37%, was achieved with DES-1 in a molar ratio of 1:2.
