Malvidin-3-glucoside cinnamic acid

Mass spectral properties of the generated anthocyanin derivatives were in line with data published for die isolated 4-vinylphenol and 4-vinylcatechol derivatives of malvidin 3-glucoside 8,15) and the tentatively identified 4-vinylguaiacol and 4-vinylsyringol adducts 14). The p-dimethylamino cinnamic acid product has not been reported before (Table...
