Abstract
The inclusion behavior of sulfobutylether-β-cyclodextrin (SBE-β-CD) with perphenazine (PPH) was first studied by flow injection (FI)-chemiluminescence (CL) analysis with proposed lg[(I0 – Is)/Is] = lgKP-CD + nlg[CPPH] model and molecular docking. Results showed that a 1:1 complex of SBE-β-CD/PPH could online form, with the formation constant KP-CD of 2.57 × 107 L mol−1 at 298 K. The thermodynamic parameters showed that the inclusion behavior of SBE-β-CD/PPH was a spontaneous process by hydrophobic interaction. The molecular docking results revealed PPH entered into the larger cavity of SBE-β-CD with two hydrogen bonds. Based on the linear relationship of the decrement of luminol/SBE-β-CD/PPH CL intensity against the logarithm of PPH concentration ranging from 0.03 to 30.0 ng mL−1, the present FI-CL analysis using luminol/ SBE-β-CD/PPH system was successfully applied to PPH determination in biological fluids and tablets with recoveries from 94.5 to 105.6% and RSDs less than 2.6% (n = 5).
