ABSTRACT

Objective To study the chemical constituents from the fruits of Ligustrum lucidum. Methods The chemical constituents in ethyl acetate fraction of 70% ethanol extract from the fruits of L. lucidum were isolated and purified by column chromatography over silica gel, ODS, Sephadex LH-20, and HPLC. The structures were identified on the basis of physicochemical properties and spectral data analyses. Results A compound, secoiridoid glucoside, was isolated and identified as 6'-O-cinnamoyl-8-ep/-kingisidic acid (1). Conclusion Comoound 1 is a new one.
