What is "mimosine"

n. (context organic compound English) A toxic alkaloid, β-3-hydroxy-4 pyridone amino acid, found in ''Mimosa'' and related plants.

Mimosine or leucenol is an alkaloid, β-3-hydroxy-4 pyridone amino acid. It is a toxic non- protein free amino acid otherwise chemically similar to tyrosine, and was first isolated from Mimosa pudica. It occurs in a few other Mimosa spp. and all members of the closely related genus Leucaena.

This compound, also known as leucenol, was first isolated from the seeds of Leucaena glauca Benth., and was later investigated by Adams and coworkers.
