The E,Z-isomerization reaction and stability of acylated anthocyanins under the influence of UV irradiation was studied. Among monoacylated anthocyanins in flower petals the E-configurated cinnamoyl derivative residues are predominant. However, these E-isomers are readily isomerized to Z-forms in ac
