Abstract
The author obtained the following results from calciun treated paper partition chromatography of vitamin A aldehyde. The Rf value of vitamin A aldehyde was found to be from 0.14 to 0.22,when petroleum benzine was used as the developing solvent. A detection of vitamin A aldehyde was done by spraying SbCl_3 solution on the paper. This method was found more sensitive than a detection by yellow color of vitamin A aldehyde itself on paper after chromatography. Vitamin A aldehyde was easily separated from its mixture with vitamin A alcohol and esters on the paper partition chromatography, on which the minimum amount of the aldehyde detected was down to 0.05 μg.
