Abstract
Es wird eine Methode zur Bestimmung biogener Amine in Blattgemüse mittels automatisierter Ionenaustausch-Chromatographie beschrieben. Die Trennung erfolgte auf einer K+-Kationenaustauschersäule mit Hilfe eines Drei-Puffer-Systems. In Chinakohl, Endivie, Eisbergsalat und Radicchio sind folgende Amine bestimmt worden: Putrescin, Histamin, Cadaverin, Spermidin, Agmatin, Spermin und Tyramin. Die Extraktion erfolgte mit 10% Trichloressigsäure. Die Gesamtkonzentration biogener Amine betrug 14–20 μg/ g Frischsubstanz. Von den nachgewiesenen Polyaminen war Spermidin mit einer Konzentration von 7–15 μg Frischsubstanz am stärksten vertreten. An automated ion-exchange Chromatographic method is described for determination of biogenic amines in leafy vegetables using a cation-exchange resin column in potassium form and a three-buffer system. The following amines were separated and quantified for Chinese cabbage, endive, iceberg lettuce and radiocchio: putrescine, histamine, cadaverine, spermidine, agmatine, spermine, tyramine. Amines from vegetable samples were extracted with 10% trichloroacetic acid. The total concentration of these amines ranged from 14 to 20 μg/g fresh weight. Spermidine was the major polyamine detected, present at concentrations of 7–15 μg/g fresh weight.Keywords
