Abstract:Methods for the isolation and identification of the pyrimidine glucoside, vicine, in extracts of broad beans, are described, By thin-layer chromatography, five fluorescing or fluorescencequenching components of the extracts are identifiable. One of them, which has been isolated from the mixture, is identified as vicine, 2:4-diamino-5:6-dihydroxypyrimidine-5-(beta-D-glucopyranoside).
