Abstract

The Weisz ring colorimetry method has been applied to the microscale determination of alkaloids The following substances were determined nicotine atropine cinchonine quinine narcotine morphine codeine aconitine strychnine and brucine The errors obtained amounted on an average to about 3 and the determinations were performed with 10–50 μg of the alkaloids investigatedDie Ringkolorimetrie nachWeisz wurde für die Mikrobestimmung von Alkaloiden herangezogen Folgende Substanzen wurden analysiert Nikotin Atropin Cinchonin Chinin Narkotin Morphin Codein Aconitin Strychnin und Brucin Die beobachteten Fehler betragen durchschnittlich ungefähr 3 Die Bestimmungen wurden mit 10 bis 50 μg des betreffenden Alkaloids durchgeführtOn a appliqué la méthode colorimétrique annulaire deWeisz au dosage dalcaloïdes à léchelle micro On a dosé les substances suivantes nicotine atropine chinchonine quinine narcotine morphine codéine aconitine strychnine et brucine Les erreurs obtenues sélevaient en moyenne à 3 environ et les dosages ont été réalisés sur 10 à 50 μg dalcaloïdes étudiés
