Abstract: | Leaves of Petaladenium (Leguminosae), an Amazonian monospecific genus recently revealed as a member of the Amburaneae clade among the earliest-diverging papilionoid legumes, were found to accumulate three monomethyl ethers of 4,5-dihydroxypipecolic acids. These were characterised by spectroscopic means as the (2S,4S,5R) and (2S,4R,5S) epimers of 5-hydroxy-4-methoxypipecolic acid and (2S,4R,5R)-4-hydroxy-5-methoxypipecolic acid. These compounds were not detected in any other genera in the Amburaneae clade or the wider Angylocalyceae-Dipterygeae-Amburaneae (ADA) clade of papilionoid legumes. Hydroxypipecolic acids, however, were detected in leaves of Myrocarpus and Myroxylon (sister genera in the Amburaneae clade), Angylocalyx and Xanthocercis (sister genera in the Angylocalyceae clade) and Monopteryx (Dipterygeae clade), and were also present in Petaladenium. Iminosugars, known to be accumulated by all four genera in the Angylocalyceae clade (Alexa, Angylocalyx, Castanospermum and Xanthocercis), were found to be characteristic of this group within the ADA clade. © 2015 Elsevier Ltd.
