Analysis of Tea Shoot Catechins: Spectrophotometric Quantitation and Selective Visualization on Two-Dimensional Paper Chromatograms Using Diazotized Sulfanilamide

A highly specific and sensitive diazotized sulfanilamide reagent is synthesized for determination of tea catechins. The reagent is employed both as spray reagent for selective visualization of tea catechins on two-dimensional paper chromatograms (sensitivity
