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 A sensitive, selective, precise, and robust high‐performance thin‐layer chromatography method was developed and validated for analysis of two new recently isolated sterols, 4α‐methyl‐24β‐ethyl‐5α‐cholesta‐14,25‐dien‐3β‐ol (**1**) and 24β‐ethylcholesta‐5,9(11),22__E__‐trien‐3β‐ol (**2**)
