摘要

A new neolignan, 5-(3 ''-acetoxypropyl)-2-(4 '-hydroxy-3 '-methoxyphenyl)-7-methoxy-3-methylbenzofuran (1) along with nine analogues were isolated from the thorns of Gleditsia japonica var. delavayi by solvent extraction and repeated column chromatography. Their structures were elucidated by means of extensive spectroscopic analysis including 1D, 2D-NMR techniques and HR-ESIMS. All the isolates were reported for the first time from this species.
