Abstract: In this paper, a kind of cyclic oligosaccharides, β-cyclodextrin was found to possess inclusion ability with bilirubin which is a metabolite of heme in senescent red blood cells.The structure of inclusion complex of β-cyclodextrin/bilirubin was determined by UVvisible spectra and X-ray powder diagrams. Experimental results indicate that 2 moles of β-cyclodextrin include one mole bilirubin to form the inclusion complex by van der Waals' force, hydrophobic interaction and hydrogen bonds.

Key words: Cyclodextrin, Bilirubin, Inclusion interaction, Cyclic oligosacchride, Inclusion complex
