Abstract:

Oleuropein is a well-known secoiridoid glucoside which is rich in the Oleaceae  family. Its structure was confirmed during 1960~1974. It has been isolated from  ma ny plants of the genus Olea, Fraxinus, Jasminum, Ligustrum and Syringa to d ate. Its  NMR data has been reported, but the detailed elucidation has not been given. Ou r recent study on the leaves of Syringa pubescens Turcz.(a  Chinese folk her b) has resulted in the isolation o f this constituent for the first time. In this paper, by utilizing a combination  of 1D and 2D NMR techniques, its 1H and 13C NMR spectra are  completely assigned  and detailedly analyzed and the characteristics of its NMR data are also pointe d out.

Key words: oleuropein,  1H and 13C NMR, 2D NMR, syringa pubescens turcz
