Description

(U-14C)-acetate, (U-14C)-threonine, (U-14C)-isoleucine, (U-14C)-valine and (2-14C)-ornithine were fed to Crotolaria retusa plants ranging in age between 4-6 months. (U-14C)-isoleucine and (U-14C)-valine showed maximum incorporation in the necic acid part of the monocrotaline molecule, while ornithine was found to be the best precursor of the retronecine part of the molecule. Intake of the precursor in the stem as well as in the leaves was maximum at the conset of fruiting. As the seeds mature their percentage of the alkolid as well as radio-activity shows an increase. Most probably seeds are the seat of storage of the alkaloid. (orig.)

Abstract (German)

(U-14C)-Acetat, (U-14C)-Threonin, (U-14C)-Isoleucin, (U-14C)-Valin und (2-14C)-Ornithin wurden 4-6 Monate alten Crotolaria retusa-Pflanzen verabreicht. Eine maximale Inkorporation von (U-14C)-Isoleucin und (U-14C)-Valin wurde im Necinsaeureanteil des Monocrolatinmolekuels festgestellt waehrend Ornithin sich als der beste Precursor des Retronecinteils des Molekuels erwies. Die Precursoraufnahme in Stengeln und Blaettern war zum Zeitpunkt des Fruchtansatzes am hoechsten. Waehrend die Samen reifen, nimmt der Anteil an Alkaloid und Radioaktivitaet zu. Das Alkaloid und Radioaktivitaet zu. Das Alkaloid wird wahrscheinlich in den Samen gespeichert. (orig.)
