Abstract:
A new secoiridoid glucoside, oleuropein-4″-methyl ether, was isolated, together with two known secoiridoid glucosides, ligstroside and oleuropein, from the leaves of Fraxinus rhynchophylla Hance by repeated column chromatography over Sephadex LH-20. The structure of the new compound has been characterized on the basis of spectroscopic evidence.
