Abstract
Enzymatic hydrolysis of oleuropein carried out in a NMR tube, gave two diastereoisomeric aglycones, which have been identified and character ized by proton and carbon NMR experiments in the same aqueous reaction medium. The stereostructures, assigned to the aglycones by NOESY spec troscopy and molecular dynamics calculation are those of two diastereo isomers, 4a and 4b.
