中文摘要:

      环糊精(CD)是由6,7,8个葡萄糖基构成的环状化合物,分别叫做α,β,γCD,它们具有“外亲水,内疏水”的独特性质,可以与多种物质形成包结物,而改变物质的特性,因而被广泛应用于各行各业中.在以往研究的基础上,总结了多种测定环糊精包结常数的方法,以便能更好地研究并开发利用具有极大潜力的环糊精.

英文摘要:

      Cyclodextrins (CDs) are cyclic oligosaccharides, mostly consisting of six,seven and eight glucoses units for α,β,γ CD respectively. They have the unique character, so they can form inclusion complexes with various guests with suitable characteristics of polarity and dimension. Formation constant is an important factor to determine the inclusion behavior. Lots of concerned methods based on references were reviewed.
