Abstract

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.

摘要

通过溶剂萃取和反复柱色谱法，从滇刺枣的刺中分离得到一种新的新木脂素5-(3″-乙酰氧基丙基)-2-(4'-羟基-3'-甲氧基苯基)-7-甲氧基-3-甲基苯并呋喃(1)及其九个类似物。通过广泛的光谱分析，包括一维、二维核磁共振技术和高分辨电喷雾电离质谱对其结构进行了鉴定。所有分离物均首次从该物种中报道。
