Formation of an inclusion complex of anthocyanin with cyclodextrin.

Β-cyclodextrin Inclusion Complex of Curcumin

Formation of inclusion complex of curcumin with β-cyclodextrin ( β-CD) has been characterized by absorption and fluorescence spectroscopy. From temperature-dependent fluorescence measurements, the thermodynamic parameters ∆H and ∆S, for the complexation were estimated. Kinetics of binding was studied by stopped flow technique, from which the binding constants for inclusion complex was estimated...

Investigation of Inclusion Complex of Patchouli Alcohol with β-Cyclodextrin

The objective of this study was to improve the stability and water-solubility of patchouli alcohol by complexing with β-cyclodextrin (β-CD). The interactions between patchouli alcohol and β-CD were characterized by differential scanning calorimetry (DSC), Fourier transformation-infrared (FT-IR) spectroscopy, powder X-ray diffraction (PXRD), and Scanning electron microscope (SEM), respectively. ...

Inclusion complex formation of cyclodextrin with its guest and their applications

Cyclodextrin (CD) are cyclic oligosaccharides consisting of glucopyranosyl units linked by α-(1,4) bonds. The widely used natural cyclodextrins are α-, βand γ-cyclodextrin consisting of 6, 7 and 8 glucopyranose units, respectively. The cyclodextrin molecules have a unique structure with a hydrophobic cavity and a hydrophilic surface which can form inclusion complex with a wide variety of guests...

Supramolecular inclusion complex formation and application of b-cyclodextrin with heteroanthracene ring cationic dyes

b-Cyclodextrin forms 1:1 inclusion complexes with methylene blue, azure A, toluidine blue, resorcinol blue, neutral red, safranine T, indigo carmine and acridine orange in aqueous media. The formation constants are determined by differential pulse polarography and spectrophotometry. The supramolecular interaction in the inclusion complexes can be employed to immobilize dyes on an electrode. Thi...
