The proton nuclear magnetic resonances (NMR) of seven naturally occurring hydroxycinnamoylquinic acids were analysed in order to obtain full sets of shift values and spin-spin coupling constants, as well as information about solution conformation. Based on this study, specific rules for proton subst
