Spectroscopic study of the interaction of catechin with α-, β-, and γ-cyclodextrins
The inclusion complex of catechin with cyclodextrins (CDxs) is examined by the use of 1H NMR, UV, and circular dichroism spectroscopies. The UV measurements demonstrate the existence of additional absorbing species of catechin in the presence of β-CDx. The 1H NMR provides evidence for the formation of inclusional complexes between catechin and β- and γ-CDxs through changes in the chemical shifts of the proton resonances of catechin and that of the protons inside the CDx activity. The apparent formation constant is estimated by use of circular dichroism. © 1994 American Chemical Society.
