Abstract

A simple assay method of methylmethionine sulfonium derivative was established utilizing the precipitation reaction with phosphotungstic acid and the coloration with potassium 1, 2-naphthocluinone-4-sulfonate. This method could satisfactorily be applied for the determination in rather complicated, mixed preparations.
