Abstract
Light scattering and NMR experiments provide evidence for the formatio n of large aggregates, like micelles, from beta-carotene complexes wit h beta- and gamma-cyclodextrin in water. High-resolution NMR spectra o f the system gamma-cyclodextrin/beta-carotene in D2O point out guest-i nduced chemical shift variation of the sugar protons, thus suggesting host-guest interaction in solution.
