    摘要: PURPOSE:To eliminate necessity of taking out and exchanging of a guard column and purify carotene, by washing silica gel or activated alumina filled in the guard column with a heated solvent in chromatographically treating a carotene concentrate. CONSTITUTION:A carotene-containing concentrate is adsorbed on a silica gel or activated alumina filled in a column as a packing. A developing solvent (e.g., hexane) is then fed to the packing to elute, separate, collect and purify carotene. The contaminated guard column packing can be then washed with a heated polar solvent (e.g., acetone) for reuse. The purification can be repeatedly carried out with remarkably reduced running cost. Carotene is useful as an edible colorant and substance having provitamin A action.
