摘要: The interaction of alkaloids with selected polyhaloquinone and polycyanoquinone π-acceptors was found to yield intensely coloured radical ions. This finding developed into a sensitive spectrophotometric assay for general applicability adequate accuracy precision. 7,7,8,8-Tetracyanoquinodimethane is used as the reagent. Anwendung von π-Acceptoren zur quantitativen Analyse Alkaloiden Alkaloide geben mit vom Typ der Polyhalogenchinone und Polycyanochinone intensiv gefarbte Radikal-Anionen. Auf Grund dieser Reaktion wurde eine allgemein anwendbare, empfindliche photometrische Bestimmungsmethode fur Alkaloide entwickelt, die auf Umsetzung 7,7,8,8-Tetracyanochinondimethan beruht.
