NEW VISUALIZING AGENTS FOR FATTY VITAMINS IN TLC

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.
