Abstract

Three new secoiridoid glucosides, ligustrosidic acid, oleuropeinic acid and neonuezhenide, were isolated from the fruits of L. japonicum and L. lucidum, and their structures were elucidated on the basis of chemical and spectral evidence. Compound IX was presumed to be the substance as G1 3 which was obtained from Fraxinus americana.
