The retention of epigallocatechin gallate (EGCG) on oligo-β-cyclodextrin (oligo-β-CD) bonded agarose chromatographic media was investigated. NMR spectroscopy in solution showed that the EGCG immerses into the β-CD cavity. The association constant calculated by NMR titration was used to estimate a retention factor which accurately reflected chromatographic behaviour. This correlation suggests that oligo-β-CD forms inclusion complexes with EGCG via the same mechanism as monomeric β-CD.
