摘要：

The antioxidant activity of feruloyl arabinose, a model substance of cereal cell-wall fragments, in the LDL autoxidation system by CuSO4 and its absorption were studied. Ferulic acid added as free acid showed little suppressive effect on LDL oxidation. However, ferulic acid sugar esters showed a positive effect. This fact indicated that affinity of LDL particle and free or bound ferulic acid is important for the suppressive effect. The HPLC analysis showed that in rats administered feruloyl arabinose, two peaks were detected with retention times lower than those of feruloyl arabinose and ferulic acid, which appeared upon beta-glucuronidase/sulfatase treatment. The study showed that the absorbed form of FAA. could be a more polar compound, possibly a conjugated form.
