UV protecting activity of ferulic acid polymeric derivative

摘要

In this work, polymeric derivative of ferulic acid was synthesized by employing ascorbic acid-H2O2 as redox initiator system at room temperature. The insertion of ferulic acid into the polymeric chain was confirmed by FT-IR analyses, and the total antioxidant capacity of the macromolecular system determined by the molybdate method, and correspond to a ferulic acid equivalent concentration of 0.59 mM. UV spectra are characterized by broad absorption bands in the UVA and UVB region, showing the efficiency of the polymeric system in preventing the UV-induced damages.
