Reaction Steps

In order to test and evaluate the equipment and methods of the present invention, pre-coated 10 cm×10 cm HPTLC plates (Whatman) and test compounds α-ionone, phenanthrenequinone and 1,2-naphthaquinone (Aldrich) were obtained. The test compounds were initially diluted with acetone to about 10 mg/ml and stock solutions stored below 4° C. The stock solutions were further diluted with acetone just before use. Ceric sulfate prepared by adding 42 g of (NH4)4Ce(SO4)4 and 56 ml of conc. H2SO4 in 1 liter of distilled water was the chromogenic reagent.
