无梗五加根中苯丙素类化合物的研究(英文)

Phenylpropanoids from Roots of Acanthopanax sessiliflorus(Rupr.et Maxim.) Seem.

从无梗五加(Acanthopanax sessiliflorus(Rupr.et Maxim.)Seem.)根70%乙醇提取物的乙酸乙酯层中提取分离得到8个苯丙素类化合物。经理化和波谱分析鉴定为(+)-表芝麻脂素(1)、(-)-芝麻脂素(2)、赛菊芋黄素(3)、洒维宁(4)、咖啡酸甲酯(5)、对羟基桂皮酸(6)、(-)-丁香脂素(7)、(+)-松脂素(8)。化合物8是首次从五加科植物中分离得到,化合物1和5是首次从五加属植物中分离得到,化合物3、6和7是首次从该植物中分离得到。

Eight phenylpropanoids were isolated from the ethyl acetate fraction of the 70% ethanol extract of the roots of Acanthopanax sessiliflorus（Rupr.et Maxim.） Seem..Their structures were elucidated by physicochemical properties and spectroscopic analysis as（＋）-episesamin（1）,（-）-sesamin（2）,helioxanthin（3）,savinin（4）,caffeic acid methyl ester（5）,p-hydroxycinnamic acid（6）,（-）-syringaresinol（7）,and（＋）-medioresinol（8）.Compound 8 was isolated from Araliaceae for the first time,compounds 1 and 5 were obtained from Acanthopanax genus for the first time,and compounds 3,6,and 7 were isolated from this plant for the first time.
