CHROMATOGRAPHY OF CHOLINE ESTERS 351 2. The esters were detected on the paper by an adaptation of the hydroxylamine-ferric chloride test for carboxylic esters, by the iodine method of Brante (1949), by the phosphotungstic acid- stannous chloride method of Chargaff et al. (1948) and, in the case ofacetylcholine, by pharmacological assay.
