Abstract
Abstract Eight 1,2-diarylethylenediamines in the meso - or DL -form produce fluorescence when heated with reducing carbohydrates in an alkaline medium. Of the diamines, meso -1,2-bis(4-methoxyphenyl)ethylenediamine is the most favourable reagent for reducing carbohydrates, including 2- deoxy sugars, amino sugars and sialic acids. The reagent permits the fluorimetric determination of reducing carbohydrates at concentrations as low as 0.2–0.9 nmol ml −1 .
