A newly synthesized hexavalent oleanolic acid/per-O-methylated α-cyclodextrin conjugate shows significant differences in NMR spectra with previously synthesized analogs. Characterization of the product by 1H NMR, 13C NMR, COSY, HSQC, HMBC, TOCSY, NOE, and ROESY experiments were performed. Detailed investigations revealed that the compound has two conformations in solution and the ratio of them was 1:1. Further variable-temperature NMR study revealed that the two conformations were stable at temperature range of 273–323 K in CDCl3 solution.
