刺五加果肉化学成分的研究

Chemical Constituents from the Pulp of Acanthopanax senticosus(Rupr. et Maxim)Harms

应用多种色谱技术进行分离纯化,从刺五加果肉水提取物中分离得到10个化合物,经理化性质和波谱分析鉴定其结构分别为左旋芝麻脂素(1)、紫丁香树脂酚(2)、6,7-二甲氧基香豆素(3)、7-羟基-6-甲氧基香豆素(4)、儿茶酚(5)、芦丁(6)、12-羟基硬脂酸(7)、豆甾醇(8)、β-谷甾醇(9)和蔗糖(10)。化合物3、4、5、7和8为首次从该植物中分得,其中化合物7为新的天然产物。

Ten compounds were isolated from the water extract of the pulp of Acanthopanax senticosus（Rupr.et Maxim）Harms by various column chromatographic techniques.The structures were elucidated on the basis of spectral data and chemical evidences.Their structures were determined as（-）-sesamin（1）,syringaresinol（2）,6,7-dimethoxycoumarin（3）,7-hydroxy-6-methoxy-coumarin（4）,catechol（5）,rutin（6）,12-hydroxy stearic acid（7）,stigmasterol（8）,β-sitosterol（9）and D-sucrose（10）.Among of them,compounds 3,4,5,7,and 8 were isolated from this plant for the first time and 7 is a new natural compound.
