Fluorescence and UV spectroscopic techniques were used to investigate the interaction of Paeonolum, one of the major bioactive components isolated from the bark of peony plant, with bovine serum albumin (BSA). Results obtained reveal that a binding interaction occurs between paeonolum and BSA under physiological conditions, and the interaction can quench the fluorescence of BSA originating from the complex formation between paeonolum and BSA. In addition, according to the thermodynamics parameters of this interaction process, it appears that this binding interaction is mainly hydrophobic in nature.

The binding studies of imidacloprid to bovine serum albumin (BSA) were investigated by UV-Vis absorption spectrum, fluorescence spectrum and synchronous fluorescence spectrometry. Under the simulative physiological conditions, fluorescence data revealed the presence of a single class of binding site on BSA and the dynamic quenching constants () were 6.851×104 L.mol-1 and 5.813×104 L.mol-1 at 310 and 315 K, respectively, proving the mode of action of imidacloprid with BSA as a static quenching. In addition, according to the Vant Hoff equation, ΔGθ <0 showed="" the="" combination="" of="" imidacloprid="" and="" bsa="" was="" a="" spontaneous="" process="" h="" sup="">θ <0 and="" s="" sup="">θ> 0, indicated an electrostatic interaction process. At the same time, synchronous fluorescence spectrum of BSA could tell us whether the conformation of BSA was changed by imidacloprid.
