紫珠的水溶性成分(英文)

Water-soluble Constituents from Callicarpa pedunculata

目的:研究中药紫珠的水溶性成分。方法:运用多种色谱技术进行分离纯化,运用光谱技术鉴定化合物结构。结果:从紫珠的水溶性提取物中分离到4个苯丙素苷类化合物,分别鉴定为连翘苷(forsythoside B,1),arenarioside(2),类叶升麻苷(acteoside,3)和异类叶升麻苷(isoacteoside,4)。结论:这4个化合物都是首次从该植物中分离得到。

AIM： To explore the water-soluble constituents from Callicarpa pedunculata. METHOD： The watersoluble constituents were isolated and purified by column chromatography, and their structures were identified by spectroscopic analyses, including 1D- and 2D-NMR data. RESULTS： Four caffeoyl phenylethanoid glycosides were purified from the water-soluble extracts of Callicarpa pedunculata R. Brown and were identified to be forsythoside B （1）, arenarioside （2）, acteoside （3） and isoacteoside （4） respectively. CONCLUSION： Compounds 1 - 4 were obtained from this plant for the first time.
