The present invention provides colorant compounds and its molecular structural formulas and methods of isolation of the colorant compounds derived from a reaction of Genipa americana genipin and glycine. The novel compounds were obtained from multiple fractioning by chromatography of the reaction resulting material. The molecular structural formulas resulted from 1H nuclear magnetic resonance spectroscopy, J-Modulation, H-H Correlation Spectroscopy experiments, and other molecular structural tools analysis. |
