Eleven new visualizing agents in the form of thirteen visualizing syst
ems have been applied to detection of selected fatty vitamins (D-2, D-
3, A, E) after their separation on adsorption and partition TLC. It wa
s found that more advantageous visualizing effects for all investigate
d vitamins were obtained on adsorption TLC compared with partition TLC
. In adsorption TLC, for majority of investigated visualizing agents,
the best limits of detection for investigated vitamins follow the sequ
ence: vitamine E, vitamine A, vitamine D-2 and D-3.
