| Summary: | Natural dye was successfully solubilised in aqueous solution in forming inclusion complex
with β-cyclodextrin (β-CD). To investigate molecular association, phase solubility studies
were undertaken. In the presence of cyclodextrin, fluorescence absorbances were
enhanced. Solid state inclusion complex was also prepared using co-precipitation method.
The solid was characterized using Fourier Transform Infrared (FTIR) and X-ray
Diffractometer (XRD). Using FTIR, the host-interaction have been evidenced by
monitoring the changes in some guest molecule band relative to those observed in the
spectra of the 1:1 physical mixtures and complex. XRD can give the order of structure in
the solid inclusion. All the data from FTIR and X-Ray studies showed that it is possible to
obtain an inclusion complex (1:1) in solid state. |
