[3H]Retronecine and [3H]necic acid-labelled senecionine and seneciphylline were prepared biosynthetically with seedlings of Senecio vulgaris L. using [2,3-3H]putrescine and [4,5-3H]isoleucine, respectively, as precursors. Lactating rats dosed with these differently labelled pyrrolizidine alkaloids (PAs) excreted within 3 h approx. 0.08% of the applied radioactivity in the milk mainly as yet not identified water-soluble retronecine-derived metabolites and with approx. 0.02% as unchanged PAs. Highest tissue levels of PAs and metabolites, 6 h after administration, were found in liver and lungs.
