The crystalline compound, obtained during the separation of choline and acetylcholine reineckates from the aqueous extract of Pueraria radix, was found to be a by-product formed during the porification of choline reineckate with acetone used as the solvent. This by-product was identified as diacetonamine reineckate. It was revealed that when reineckates in general are allowed to stand in acetone, the reineckate ion [Cr-(NH3)2(SCN)4]- liberates NH3 group which adds to mesityl oxide, (CH3)2-C=CH-CO-CH3, the dimer of acetone, to form diacetonamine, (CH3)2-C(NH2)-CH2-CO-CH3.
