Fig. 1. Anthocyanins, 3-deoxyanthocyanins, auronidin and their respective aglycones together with two riccionidin A synthetic models (Glc = Glucose or other sugars, in the case of the reported auronidin is neohesperidoside) (Berland et al., 2019).The scope of this work is to investigate the kinetics and thermodynamics of the multistate of riccionidin A (liverworts colorant) and compare with the similar multistates reported for 3-deoxyanthocyanidins (mosses and ferns colorants) and anthocyanins (angiosperms colorants).
