Abstract
Provided are entrapped β-cyclodextrin polymers and a method of preparing the same. Particularly, entrapped β-cyclodextrin polymers are prepared by adding epichlorohydrin to β-cyclodextrin to prepare a polymer in a gel state, entrapping the polymer by entrapment of metal ions on the surface of the polymer and pulverizing the entrapped polymer to prepare powders. According to the entrapped β-cyclodextrin polymers, steroid hormones contained in a biological sample can be simply extracted without using an additional device required in conventional solid-phase extraction.
