摘要:

以《标准样品工作导则(3)标准样品 定值的一般原则和统计方法》为依据,研制银杏内酯C的国家标准样品。样品原料为银杏科植物银杏Ginkgo biloba L.的干燥叶,采用硅胶柱色谱和Sephadex LH-20凝胶柱色谱技术,结合制备液相精制,纯化和制备了银杏内酯C,并通过紫外、红外、质谱和核磁共振等技术手段进行了结构确认。进行了薄层色谱鉴别,建立了液质联用分析技术,进行了均匀性、稳定性和定值实验。结果表明,样品均匀性良好,在0~4 ℃ 储存条件下2年内稳定,定值结果确定其纯度为(99.85±0.06)%。研制的银杏内酯C符合国家标准样品的要求,可用于与银杏内酯C相关产品的含量测定、质量控制和检测方法的评定等。

Abstract:

To develop a national certified reference material (CRM) of Ginkgolide C according to the technical requirements of Directives for the work of reference materials - Reference materials - General and statistical principles for certification, Ginkgolide C was purified and obtained using silica gel column chromatography, Sephadex LH-20 gel column chromatography technology, and preparative liquid chromatography from dried leaves of Ginkgo biloba L. The structure was confirmed by UV, IR, HR-MS, 1H-NMR, and 13C-NMR. The identification of thin-layer chromatography was performed, and the LC-MS technique was established. Homogeneity test, stability test, and certification analysis were conducted. Results show that the samples were stable under the storage condition of 0~4 ℃ for 2 years; the certification analysis result confirms that its purity is (99.85±0.06)%. The developed Ginkgolide C meets the technical requirements of national certified reference material per GB/T 15000.3—2008, which can be used for content determination, quality control, and detection method evaluation of Ginkgolide C and related products.

Key words: certified reference material, Ginkgolides C, purity analysis, homogeneity test, stability test, certification analysis
