目的：运用近红外(NIR)漫反射光谱法建立不同厂家注射用单唾液酸四己糖神经节苷脂钠(注射用GM1)的特征谱段相关系数模型，为该品种药品(国产)快速检验提供依据。方法：对国内2个厂家的共9个批次注射用GM1进行研究，通过扫描其近红外光谱，建立注射用GM1的特征谱段相关系数模型，并验证模型的准确性和可传递性。结果：建立的相关系数模型能够准确区分2个厂家的样品。结论：本方法简便、快捷、可靠，可对国内不同厂家生产的注射用GM1进行快速的初步定性分析，适用于药品检验车的快速无损检测。“,”Objective:To construct characteristic spectral correlation coefficient model for monosialotetrahexosyl ganglioside sodi-um injections ( GM1 injections) from different manufacturers by near-infrared ( NIR) diffuse reflectance spectroscopy to provide refer-ence for the rapid test. Methods:NIR spectral correlation coefficient model for 9 batches of GM1 injections from 2 manufacturers was constructed, and the accuracy and transitivity of the model was validated. Results: The correlation coefficient model can accurately distinguish the samples from the 2 manufacturers. Conclusion:The method is simple, fast and reliable, and has the potential to be em-ployed in the mobile laboratory to identify GM1 injections.
