The dynamics of the anthocyanin content reduction in the course of aging of the Ipomoea purpureа petals, which characterizes the rate of the degradation processes in a cell, has been studied. The analysis included the impact of various UV-B radiation doses on the rate of anthocyanin age-related decomposition. The experiment proved that but one dose – 12.6 kJ/m2 contributed to the deceleration of the anthocyanin decomposition rate, within the range studied. The probable mechanisms that connect ageing and pigment degradation are being discussed.
