The interconversion kinetics of astilbin to a mixture of their respective diasteroisomers was studied by nuclear magnetic resonance spectroscopy using selective irradiation experiments (TOCSY) in dimethylsulfoxide. It is proposed a model which allowed establishing a trend to equilibrium for H-3 (astilbin interconversion to neoisoastilbin)
