Policosanol is contained in rice bran and is known as a functional ingredient that has effects such as improvement of athletic ability and stress tolerance. But it has low water solubility and therefore low absorbability. In this study, for the purpose of improvement of intestinal absorbability by cyclodextrins (CDs), preparation of policosanol inclusion complexes using CDs and their solubility in artificial intestinal fluid were evaluated. As a result, we found that α-CD increased the solubility of policosanol, which may show the absorption enhancement. |
