One of the active components of Cruculon (Takeda), a curcuma preparation, is said to be ferulic acid and its quantitative determination has already been reported. Having observed that the vanillic acid present as a contaminant in the ferulic acid hinders the colorimetric determination of the latter the separation of both compounds by paper chromatography was carried out and the separated ferulic acid was colorimetrically determined by diazotized sulfanilic acid solution. So far as the authors' experiments are concerned, the most suitable developing solvent for the paper chromatographic separation is 2.5% aqueous solution of boric acid.
