[Study on solubilization effect of solid dispersion technology and inclusion technology on pulsatillae total
Objective:
To study the effect of solid dispersion technology and inclusion technology on dissolution performance of Pulsatillae total saponins, and preliminarily investigate its mechanism.
Method:
The solid dispersion of Pulsatillae total saponins-PEG 4000 was prepared by the melting method. The inclusion compound of Pulsatillae total saponins-hydroxypropyl-beta-cyclodextrin ( HP-beta-CD) was prepared by the freeze-drying method. The properties of solid dispersion and inclusion compound were identified by using IR, DSC and NMR. And the dissolution of solid dispersion and inclusion compound were also determined by the small glass method.
Result:
IR, DSC and NMR results showed the formation of solid dispersion and inclusion compound. In terms of the dissolution, the inclusion compound ranked first, which was followed by solid dispersion and bulk pharmaceutical chemicals.
Conclusion:
The inclusion technology could significantly increase the dissolution of Pulsatillae total saponins, whereas the solid dispersion showed no notable solubilization effect.

Solubility
A solution is a homogeneous mixture composed of a solvent, the major component, and a solute, the minor component. The physical state of a solution—solid, liquid, or gas—is typically the same as that of the solvent. Solute concentrations are often described with qualitative terms such as dilute (of relatively low concentration) and concentrated (of relatively high concentration).
In a solution, the solute particles (molecules,...
