浆果楝中的新木脂素(英文)

Lignans from the Stem of Cipadessa baccifera(Meliaceae)

从浆果楝(Cipadessa baccifera)中分离得到两个木脂素,其化学结构通过波谱方法鉴定为:(-)-9′-O-(E)-coumarate-5,5′-dimethoxylariciresinol(1)和(+)-9′-O-(E)-feruloyl-5,5′-dimethoxylariciresinol(2)。其中化合物1为新化合物。

One new lignan,（-）-9＇-O-（E）-coumarate-5,5＇-dimethoxylariciresinol（1）,together with one known compound,（＋）-9＇-O-（E）-feruloyl-5,5＇-dimethoxylariciresinol（2）was isolated from the stem of Cipadessa baccifera.The new structure was elucidated by spectroscopic methods.
