Saccharin is extracted from the acidified liquid food with chloroform. This solvent is evaporated ; the residue is dissolved in ethyl acetate and applied on a silica gel GF,,, plate. After chromatographic separation, the saccharin band is scraped off and extracted with 1 % sodium carbonate solution.
A rapid thin-layer chromatographic method on Gelman I.T.L.C. type SA plates for the determination of choline acetylase activity has been developed. The mobile phase consists of sodium tetraphenylboron dissolved in acetonitrile. The Rt values for acetyl coenzyme A and acetate are about 0.1, while tha
## Abstract The measure of the distribution of a mixture of substances in TLC with a binary mobile phase is expressed as ΔRM which represents the difference between the R~M~ values of substances i and j on use of the binary solvent 1 + 2 as the mobile phase. The possibility of determining its maxim
