Abstract
Seeds from mature flowers of Heracleum laciniatum were collected locally (Tromsø, Norway). Seed coats were removed and the seeds were analyzed for their content of free, free plus ester-conjugate, and total indole-3-acetic acid (IAA) by quantitative gas chromatography-mass spectrometry. Seeds contained high levels of free and amide-linked IAA relative to other dicotyledonous seeds for which values have been published. The major amide conjugate in this material was identified as indole-3-acetylaspartate by gas chromatography-mass spectrometry of its bis-methyl ester.
