零陵香中发现一种新的黄酮苷类化合物

A new flavonoid from Lysimachia foenum-graecum

为了研究零陵香(Lysimachia foenum-graecum Hance)的化学成分,将零陵香用70%乙醇提取,采用多种色谱方法进行分离纯化,得到了一个黄酮类成分,根据化合物的理化性质和光谱数据进行结构鉴定,鉴定为kaempferol-7-O-(4″-(E)-p-coumaroyl-)-α-L-rhmanopyranosyl)-3-O-β-D-glucopyranosyl(1→4)-α-L-rhmanopyranosyl(1→2)-β-D-glucopyranoside。该化合物为一新化合物。

The aim of the study was to look for the chemical constituents of the herb of Lysimachia foenum-graecum. The herb of Lysimachia foenum-graecum was extracted with 70% EtOH. The isolation and purification was performed with a combination of multi-column chromatography and the structure was determined by spectral analysis. The flavonoid compound was obtained and elucidated as kaempferol-7-O- （4″-（ E ）-p-coumaroyl-）-α-L-rhmanopyranosyl ）-3-O-β-D-glucopyranosyl （ 1 ＋ 4 ）-a-L-rhmanopyranosyl （1→2）-β-D-glucopyranoside. It is a new flavonoid compound.
