This study focuses on the complex formed between α-cyclodextrin (CD) and the anti-inflammatory drug diclofenac in aqueous solution and also on its potential analytical applications. It was corroborated that the fluorescence emission band of diclofenac is significantly intensified in the presence of α-CD. From the changes in the fluorescence spectra, it was concluded that α-CD forms a 1:1 inclusional...
The inclusional complexation between cyclodextrins (CDs) and salicylate (SA) in aqueous solution is studied. While no changes in both the absorbance and fluorescence spectra are detected when α- and γ-CDs are added to aqueous solutions of SA, spectral variations are produced by the presence of β-CD. An 1:1 SA-β-CD complex is detected and its equilibrium constant is determined by both absorptimetric...
