抄録

A simple method for the simultaneous determination of the lower- and higher-sulfonated subsidiary colors in Food Red No. 40 by high performance liquid chromatography was developed.<br>The sample solution was directly chromatographed on an ODS-column with a gradient of 0% to 100% methanol in 0.1M ammonium acetate over 50min. Detection was achieved with a VIS monitor set at 515nm.<br>In analysis of commercial Food Red No. 40, the sum of lower-sulfonated subsidiary colors was 0.28% to 1.31%, and the sum of higher-sulfonated ones was 0.14% to 0.60%. The detection limits of quantitative determination by the proposed method were 0.02% for each compound. These techniques enable us to monitor rapidly some subsidiary colors in commercial samples.
