The interaction between xanthoxylin (XT) and bovine serum albumin (BSA) under simulative physiological conditions has been analyzed in detail by various spectroscopic techniques including fluorescence, circular dichroism (CD), and Fourier transform infrared (FT-IR) spectroscopy. Fluorescence quenching data revealed that the quenching constants (K) were 3.31×105, 2.03×105 and 0.94×105 L·mol−1 at 286, 298 and 310 K, respectively. Based on the fluorescence results, the fluorescence quenching mechanism of the interaction between XT and BSA has been found to be combined static and dynamic quenching. Thermodynamic parameters ΔH0, ΔS0 and ΔG0 suggested that the hydrophobic force played a main role in binding of XT to BSA. The effect of XT on the conformation of BSA was analyzed by FT-IR spectroscopy and quantitatively calculated from CD spectroscopy with reduction of α-helical content by about 3.9%. In addition, the effect of common ions on the binding constant was also discussed.
