Abstract

Aim: To determine the 3D structure of anemoside A3 (3β,23-dihydroxyl-lup-20(29)-en-28-oic acid-3-O-α-L-rhanmopyranosyl(1→2) -α-L-arabinopyranoside) in the solution. Methods: A series of 1D and 2D NMR spectra of anemoside A3 we re recorded. Program Hyperchem 7.0 was used for constrained molecular simulation with constraints derived from NMR data. Results: All the proton and carbon signals were assigned. The calculation yielded a group of well-defined global minimum solution conformations. Conclusion: The results could be used for the study of structure-activity relationships of triterpenoid glycosides.
