Inclusion compounds of catechin and cyclodextrin were formed. Inclusion was by maceration without solvent, with hexane and supercritical CO2. H NMR, XRD, FT-IR/ATR, FT-Raman, TGA and DSC analyses confirmed inclusion. The complexation method had no marked effect on the antioxidant activity of complexes. Complexation increased significantly the equilibrium antioxidant activity.
