Studies on the Constituents of Ligustrum Species. XI. On Secoiridoids of the Fruits of Ligustrum japonicum THUNB. and L. lucidum AIT. (2)

Abstract

Three new secoiridoid glucosides, named ligustrosidic acid (V), oleuropeinic acid (VI) and neonuezhenide (VIII), have been isolated from the fruits of Ligustrum japonicum and Ligustrum lucidum, and their structures have been elucidated on the basis of chemical and spectral evidence. Compound IX has been presumed to be the substance as Gl 3 which was obtained from Fraxinus americana.
