Some acetylcholine-like substances from several kinds of domestic honey were examined by the Magnus method and by paper partition chromatography, and calculated value of 0.1-15γ/g. (average, 10.3γ/g.) was obtained. Honey with its source from Tilia japonica Sink. was found to contain practically no acetylcholine-like substance. The content of such substance in honey collected in different parts of the country was found to be approximately the same when the plant source of honey was of similar species. The content of vitamin B group in honey purified by Japanese acid clay, kaolin, or activated carbon was found to be extremely smaller than in the original honey.
