Antioxidant Activity of Ferulic Acid β-Glucuronide in the LDL Oxidation System

Abstract

Antioxidant activity of ferulic acid β-glucuronide, which is prepared from the plasma of feruloyl arabinose fed rats, in the CuSO₄-induced LDL autoxidation system was studied. It has been found that absorbed ferulic acid occurred as the β-glucuronide and that the antioxidant activity of ferulic acid β-glucuronide, which has not only the hydrophobic ferulic acid moiety but also a hydrophilic sugar moiety, is stronger than ferulic acid in the LDL oxidation system.
