Abstract

Two novel unsaturated E‐ring pentacyclic triterpenoid saponins, ilexhainanoside A and ilexhainanoside B, were isolated from the leaves of Ilex hainanensis. Their chemical structures were determined by MS, NMR spectroscopy and chemical analysis. Complete assignments of the ^1^H and ^13^C NMR spectroscopic data were achieved by 1D and 2D NMR experiments (HSQC, HMBC, ROESY and ^1^H–^1^H COSY). Copyright © 2006 John Wiley & Sons, Ltd.
