Abstract
INTERFERENCE of trichloracetic acid with the paper chromatography of adrenaline analogues and of histamine, using n-butanol/acetic acid/water (4:1:5), has already been reported1,2. A similar artefact is described below, affecting another compound, thyrox-ine, run in a different solvent system, n-butanol/ dioxane/2 N ammonia (4: 1: 5). No effect of this nature is mentioned by Gross3 in his review on the chromatography of thyroid hormones.
