摘要建立高效液相色谱法和高效毛细管电泳法,对研制的西洋参基体标准物质中人参皂苷Rg₁、Re、Rb₁含量进行准确定值,同时考察了样品的均匀性、稳定性和样品的最小取样量,最后对标准物质的不确定度进行了评定。评定结果为人参皂苷Rg₁、Re、Rb₁含量分别为（1.72±0.14）mg/g、（15.3±1.5）mg/g、（25.8±2.8）mg/g,相对扩展不确定度分别为8.4％、10％、11％,可为西洋参的质量控制提供依据。

Abstract：A new certified reference material (CRM) of ginsenoside Rg₁, Re, and Rb₁ in Panax quinquefolium is developed and measured by two different methods, high performance liquid chromatography method and high performance capillary electrophoresis method.Simultaneously, the homogeneity and the stability are studied, and the evaluation of uncertainty is calculated. The mass fractions of ginsenoside Rg₁, Re, and Rb₁ are (1.72±0.14)mg/g, (15.3±1.5)mg/g, (25.8±2.8)mg/g, with the expanded uncertainty of 8.3％, 10％, 11％.The new certified reference material of ginsenoside Rg1, Re, and Rb1 in Panax quinquefolium is capable to validate analytical measurements in laboratories.

Key words： Metrology Standard certified reference material Panax quinquefolium Ginsenoside Rg₁ Ginsenoside Re Ginsenoside Rb₁
