摘　　要：目的研究西伯利亚蓼Polygonum sibiricum Laxm.的化学成分。方法西伯利亚蓼70%乙醇提取物采用硅胶、D101、Sephadex LH-20、半制备HPLC进行分离纯化,根据理化性质及波谱数据鉴定所得化合物的结构。结果从中分离得到9个化合物,分别鉴定为紫云英苷(1)、异槲皮苷(2)、异牡荆苷(3)、毛果南烛素甲苷元(4)、(6S,9R)-长寿花糖苷(5)、corchoionoside C (6)、阿魏酸(7)、邻苯二酚(8)、二十四烷酸(9)。结论所有化合物均为首次从该植物中分离得到。AIM To study the chemical constituents from Polygonum sibiricum Laxm..METHODS The 70% ethanol extract from P. sibiricum was isolated and purified by silica,D101,Sephadex LH-20 and semi-preparative HPLC,then the structures of obtained compounds were identified by physicochemical properties and spectral data. RESULTS Nine compounds were isolated and identified as astragalin(1), isoquercitrin(2), isovitexin(3), lyohebecarpiin A(4),(6S,9R)-roseoside(5), corchoionoside C(6), ferulic acid(7), o-benzenediol(8), tetracosanoic acid(9). CONCLUSION All the compounds are isolated from this plant for the first time.
