Abstract:

BACKGROUND: Curcumin has good anticancer and anti-inflammatory effects, but which is limited for the low solubility.

OBJECTIVE: To investigate the intestinal absorption characteristics of curcumin hydroxypropyl-β-cyclodextrin and curcumin in rats.
METHODS: The curcumin hydroxypropyl-β-cyclodextrin was prepared by grinding method, and the solubility of curcumin hydroxypropyl-β-cyclodextrin and curcumin was detected. Twelve male Sprague-Dawley rats were used to establish a one-way perfusion model of intestinal segment (duodenum, jejunum, ileum and colon), and randomly divided into two groups. The experimental group was given curcumin hydroxypropyl-β-cyclodextrin, and the control group was perfused with curcumin suspension. The absorption rate (Ka) and effective permeability (Papp) of curcumin hydroxypropyl-β-cyclodextrin and curcumin at each intestinal segment were measured by ultraviolet-visible spectrophotometry.

RESULTS AND CONCLUSION: The solubility of curcumin hydroxypropyl-β-cyclodextrin in water was increased by 33.68 times compared with that of curcumin. The absorption rate constant (Ka) of curcumin hydroxypropyl-β-cyclodextrin was ranked as follows: duodenum > ileum > jejunum > colon, and the effective permeability (Papp) was ranked as follows: colon > duodenum > ileum > jejunum, and the absorption in the intestines was significantly higher than that of curcumin (P < 0.05). In summary, curcumin hydroxypropyl-β-cyclodextrin can obviously improve the absorption of curcumin in the intestines of rats.
