小蓟中一个新的苯丙素苷类化合物(英文)

A new phenylpropanoid glycoside from Cirsium setosum

为研究小蓟Cirsium setosum(Willd.)MB.地上部分的化学成分,采用硅胶、树脂和凝胶柱色谱法从其70%乙醇提取物中分离得到4个化合物,并根据理化性质和波谱数据鉴定其结构分别为银槭醇9-O-反式-对-香豆酰基-4-O-β-D-葡萄糖苷(1)、lycoperodine-1(2)、芹菜素-7-O-(6"-反式-对-香豆酰基)-β-D-半乳糖苷(3)和槲皮素(4)。其中,化合物1为新化合物,化合物2为首次从该属植物中分离得到,化合物3和4为首次从该植物中分离得到。

To study the chemical constituents of Cirsium setosum（Willd.） MB.,70% ethanol extract of the aerial parts was subjected to column chromatography.One new phenylpropanoid glycoside,sinapyl alcohol 9-O-（E）-p-coumaroyl-4-O-β-D-glucopyanoside（1） was isolated,along with three known compounds：lycoperodine-1（2）,apigenin-7-O-（6″-（E）-p-coumaroyl）-β-D-galactopyranoside（3） and quercetin（4）.The structures were elucidated on the basis of spectral and chemical evidence.Compound 2 was obtained from Cirsium genus for the first time,compounds 3 and 4 were obtained from this plant for the first time.
