A study of fluorescence properties of citrinin in β-cyclodextrin aqueous solution and different solvents

► The effects of pH, solvents and β-CD on the fluorescence of citrinin are analyzed. ► [H]+, acetic acid, β-CD and acetonitrile can induce CIT fluorescence enhancement. ► Methanol and H2O can induce CIT fluorescence reduction. ► The 1:1 inclusion complex of CIT/β-CD can form in acidic phosphate solution.
