绵参中苯丙素类成分的研究

Studies on phenylpropanoids from herbs of Eriophyton wallichii

目的:研究绵参Eriophyton wallichii的化学成分。方法:乙醇总提物经反复硅胶柱色谱,Sephadex LH-20,ODS-A等进行分离纯化,利用各种波谱分析手段鉴定化合物的结构。结果:分离鉴定了8个苯丙素类化合物,地黄苷martynoside(1),leucosceptoside A(2),枸橼苦素(citrusin B,3),(+)-dehydrodiconiferyl alcohol-4,9-β-D-glucopyranoside(4),鹅掌楸碱(liriodendrin,5),velutinosideⅢ(6),苦奥诺苷B1(jionoside B1,7),stachysoside D(8)。结论:这8个化合物均为首次从绵参中分离得到。

Objective： To study the chemical constituents of Eriophyton wallichii. Method： Compounds were separated and purified by column chromatographic methods, and their structures were elucidated by spectroscopic methods. Result： Eight phenylpro- panoids were isolated and identified as martynoside （1）, leucosceptoside A （2）, citrusin B （3）, （ ＋ ）-dehydrodiconiferyl alcohol-d, 9-B-D-glucopyranoside （4）, liriodendrin （5）, velutinoside Ⅲ （6）, jionoside B1 （7）, stachysoside D （8）, respectively. Conclusion： The eight compounds were firstly isolated from E. wallichii.
