目的
2
分别采用质量平衡法和定量核磁共振法对安格洛苷C开展对照品定值研究。
方法
2
采用紫外光谱、红外光谱、质谱及核磁共振波谱对安格洛苷C样品进行结构确认;采用薄层色谱法和高效液相色谱法对其进行纯度检查;同时测定样品中水分、残留溶剂及炽灼残渣,进行均匀性及稳定性检查。以质量平衡法对安格洛苷C进行定值研究,计算其不确定度;并以定量核磁共振法进一步对该样品进行定值研究,加以佐证。
结果
2
质量平衡法的定值结果为94.04%,扩展不确定度为0.088%;定量核磁共振法的定值结果为94.06%。
结论
2
质量平衡法与定量核磁共振法对安格洛苷C定值结果基本一致。两种方法相互佐证,能够更好地保证安格洛苷C对照品定值的准确性,为该对照品的研发奠定基础。
Objective
2
To study the reference substance of angoroside C using mass balance method and quantitative nuclear magnetic resonance method .
Methods
2
The structure was confirmed by ultraviolet-visible spectrometry
infrared spectrum
mass spectrometry
and nuclear magnetic resonance. The purity was checked by thin layer chromatography and high pressure chromatography. The moisture content
residual solvent
and ignition residue in the sample were determined
and the uniformity and stability were checked. The mass balance method was used to determine the value of angoroside C
and the uncertainty was calculated. The content of angoroside C was further determined by quantitative nuclear magnetic resonance method
and the assignment result were verified.
Results
2
The certification result of the mass balance method was 94.04%
and the expanded uncertainty was 0.088%. The result of quantitative nuclear magnetic resonance method was 94.06%.
Conclusion
2
The certification result of angeloside C using the mass balance method and the quantitative nuclear magnetic resonance method were basically consistent. The two method corroborate each other
which can better ensure the accuracy of the certification of angoroside C
and lay a foundation for the research and development of its reference substance.
