Abstract
A method for separating and purifying cyclodextrins is disclosed. This method is also able to sequentially separate alpha, beta and gamma cyclodextrins. The method entails forming a matrix with an inclusion compound bound thereto and passing an aqueous solution containing cyclodextrin through the matrix and eluting the cyclodextrins in a sequential order. The inclusion compound bound to the matrix determines the order in which the cyclodextrins are eluted.
