A simple detection of fat-soluble vitamins on alumina thin layer-chromatograms

A Simple, Specific Spray for the Detection of Phospholipids on Thin-layer Chromatograms.

Spray detection of phospholipids on thin-layer chromatograms.

A new spray reagent with copper, ammonium molybdate, and sulphuric acid for the detection of phospholipids on thin-layer chromatograms is described. The specificity and sensitivity of the spray reagent is also shown.

Fat-soluble vitamins.

Modified spray for the detection of phospholipids on thin-layer chromatograms.

A simplified method for the preparation of the Dittmer-Lester spray for the detection of phospholipids on thin-layer chromatograms is described.

Modification of the Dittmer-Lester reagent for the detection of phospholipid derivatives on thin-layer chromatograms.

A simple modification of the Dittmer-Lester reagent is described that allow the detection of phospholipid derivatives at very low concentrations on silica gel and reversed-phase thin-layer plates. This modification, which involves the addition of acetic acid to the mixture, permits the observation of sharp blue spots on a white background. The specificity and sensitivity of the spray are discus...
