Amine distribution and content in several parts of the subantarctic endemic species Lyallia kerguelensis (Hectorellaceae)

The leaves, stems and roots of the subantarctic endemic species from Kerguelen Lyallia kerguelensis showed different patterns of amine accumulation. The leaves contained the highest free amine, stems the intermediate and roots the lowest content. Leaves accumulated massively agmatine and tyramine, whereas stems contained high levels of octopamine and spermidine. A high content of an amine which was co-chromatographed with homospermidine was observed in leaves and stems. Conjugated amines did not accumulate to any significant extent in stems and roots, whereas they were detected in high amounts in leaves.
