Phenolic compounds show a variety of biological activities including antioxidant, anti-inflammatory, anti-fibrosis, and so on. While there have been many studies to determine the antioxidant activity for a variety of dietary phenolic compounds, the protein binding may affect the activity of antioxidants in foods. In the present study, the effect of bovine serum albumin (BSA) on the antioxidant activity of selected phenolic compounds, ellagic acid and propyl gallate, was investigated using the Trolox equivalent antioxidant capacity (TEAC) assay. Antioxidant activities of ellagic acid and propyl gallate with binding to BSA were measured and the results were compared to those of free phenolic compounds. In addition, the binding interactions of these phenolic compounds with BSA were studied using fluorescence spectroscopy. The observed behavior in the antioxidant activity of the protein-phenolic compound systems was discussed on the basis of interactions between the protein and phenolic compound.
