EVALUATION OF SOLID-STATE FORMS OF CURCUMINOIDS
AbstractCurcuminoids are dietary phytochemicals obtained from dried rhizomes of turmeric plant (Curcuma longa). Curcuminoids are mixture of curcumin, demethoxy curcumin and bisdemethoxy curcumin in which curcumin is a major constituent. Several polymorphic forms of curcumin were reported. The present study relates to the preparation of different solid forms of curcuminoids and to study the influence of other constituents of curcuminoids on the polymorphic behaviour of curcumin. The developed solid forms were characterized by various spectral methods like Fourier Transform Infrared Spectroscopy (FTIR), Powder X- ray diffraction (PXRD), Differential Scanning Calorimetry (DSC) and Scanning Electron microscopy (SEM). On crystallization from ethanol and upon melt crystallization, curcuminoids underwent transformation into an amorphous form. Grinding did not affect the polymorphic nature of curcuminoids. These findings suggest that curcuminoids undergo polymorphic modifications very similar to curcumin.
