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...
متن کاملComparison of ibuprofen release from minitablets and capsules containing ibuprofen: β-cyclodextrin complex.
Mixtures containing ibuprofen (IB) complexed with β-cyclodextrin (βCD) obtained by two complexation methods [suspension/solution (with water removed by air stream, spray- and freeze-drying) and kneading technique] were processed into pharmaceutical dosage forms (minitablets and capsules). Powders (IB, βCD and IBβCD) were characterized for moisture content, densities (true and bulk), angle of re...
متن کاملInclusion 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...
متن کاملSupramolecular 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...
متن کاملStudy 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...
