A spontaneous reaction of genipin and glycine gave a blue dimeric 1:1 adduct, whose structure was determined as 1 based on instrumental analyses, in particular, nOe experiments in 1H-NMR spectroscopy.

The present disclosure provides colorant compounds and methods of isolation of the colorant compounds derived from a reaction of genipin and an amine. The colorant compositions comprise purified compounds (e.g., a purified polymer or a purified dimer) obtained from multiple fractioning by chromatography of the reaction resulting material. The purified polymer or dimer can be used as a colorant by itself or in combination with another colorant for imparting color to a food, a drug, a cosmetic, a medical device, and textile products.
