The inclusion complex formation of curcumin with β-CD was studied by spectrophotometry,and the apparent formation constant for curcumin-β-CD complex was determined.The stiochiometric ratio of curcumin-β-CD complex was investigated by Job’s continuous variation methods.The results showed that a 1:1 complex between curcumin and β-CD was formed,and the apparent formation constants decreased with the increase of reaction temperature.The thermodynamic parameters,standard free energy (ΔG°),enthalpy (ΔH°) and entropy (ΔS°) for complex f...
