[Preparation of curcumin solid dispersion and inclusion complex].

Objective: To prepare the curcumin solid dispersion and the curcumin inclusion complex, evaluate its stability and the transdermal properties.

Methods: The samples were prepared with hydrophilic, or water-soluble polymers, by solvent and solvent-melting methods. The optical microscope and the melting point were used to identify the state of the drug existence in it, and UV-Vis spectrophotometer was used to determine the solubility and content of different samples.

[Study on the preparation of curcumin inclusion complex and its stability].

Objective: To prepare the curcumin inclusion complex and study its stability.

Methods: Beta-cyclodextrin (beta-CD) was chosen as inclusion material and orthogonal design method was used. UV-Vis spectrophotometer was used to determine the solubility and content of different samples.
