Abstract:
The inclusion complex of cordycepin ( COR ) with hydroxypropyl-β-cyclodextrin ( HPβCD ) was prepared by the method of saturated solution. The inclusion of HPβCD with COR in aqueous solution was studied by UV-vis spectroscopy, and the inclusion ratio of COR/HPβCD complex was determined with the Job plots. The COR/HPβCD complex was characterized and determined by means of 1 H NMR and 2D NMR, differential scanning calorimetry ( DSC ) , thermogravimetric analysis ( TG ) , X-ray diffraction ( XRD ) , Fourier transform infrared spectroscopy ( FTIR) and scanning electron microscope ( SEM) . The results showed that the COR/HPβCD complex ratio was 1:1 and the water solubility and stability of COR were obviously increased in the inclusion complex with HPβCD. The COR/HPβCD complex will be potentially useful for its medical application.
