摘要:

建立蒜氨酸标准物质的定值方法。鲜蒜经一系列提取、分离、纯化得蒜氨酸标准物质。应用高效液相色谱面积归一法确定蒜氨酸标准物质的纯度。随机抽取10 瓶样品进行均匀性检验,经F检验,样品均匀性良好。长期稳定性结果经t检验表明在4 ℃条件下蒜氨酸的稳定期不少于43 个月。采取9 个实验室协作定值的方法对样品进行检测定值,定值结果由标准值和不确定度表示为(99.49±0.95)%。研制的蒜氨酸标准物质通过了国家标准委的审评,并已应用于实际检测中。

Abstract:

A methodology regarding certification of certified reference material (CRM) of alliin was presented. The CRM
was prepared from fresh garlic by a series of extraction, separation and purification. The purity of the CRM was determined
by area normalization method. For the analysis of homogeneity, 10 bottles of samples were randomly taken. The results
were validated by F-test statistical method and showed that the homogeneity of samples was good. The results of longterm
stability for alliin were validated by t-test statistical method and indicated that the storage duration for alliin at 4 ℃
was 43 months. A cooperative certification test was conducted by 9 laboratories. The property value was determined to be
(99.49 ± 0.95)%. The CRM has passed the evaluation made by the Standardization Administration of the People’s Republic
of China and has been applied in the actual detection.

Key words: alliin, certified reference material, homogeneity, stability, certification
