Simplified Method of Determination of Serum Cholesterol Sulfate by Reverse Phase Thin-Layer Chromatography

A simplified method for rapid determination of porphyrins by thin-layer chromatography.

Free porphyrins, especially copro-, uro-, and protoporphyrin, were successfully separated by talc thin-layer chromatography (TLC), and were determined from the relationship of the weight and the area of porphyrins in the spot on the thin-layer plate. The results obtained from both the solvent extraction and the simple, rapid TLC method reported in this paper showed good correlation for copropor...

Determination of carotenes by thin-layer chromatography.

The carotenoids of yellow, red and tangerine tomato fruits were separated and identified by thin-layer chromatography (TLC). β-carotene is extracted with a mixture content hexan and acetone. The various systems of adsorbents and solvents for TLC of carote and tomato carotenes were examined, and it was revealed that the most suitable TLC system for separation and identification was silica gel pl...
