Mimosine was first isolated from the sap of Mimosa pudica by Renz [7] and was given the name
“mimosine”. Later, minosine was biologically characterized from M. pudica by Nienburg and
Taubõck [8]. From the extraction of ground Leucaena glauca seeds, Mascré [9] successfully
isolated an optically inactive crystal line solid, m.p.287oC named “leucenol”.
