Structure of .BETA.-cyclodextrin inclusion complex with nicotinamide.

Study of inclusion complex of beta-cyclodextrin and nitrobenzene.

beta-cyclodextrin can react with nitrobenzene to form an inclusion complex which is characterized by (1)H NMR and powder X-ray diffractometry. The ratio of beta-CD to NB in inclusion complex is determined as 1:1. At 25 degrees C, the dissociated constant, K(D), of the inclusion complex is measured as 6.5 x 10(-3) M in neutral solution (pH=7.0), but in alkali (pH=13.5), K(D) is 3.2 x 10(-2) M wh...

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. ...
