目的:利用近红外光谱快速鉴别氨糖美辛肠溶铝塑片的真伪。方法:在4 200～10 000 cm~(-1)范围内对氨糖美辛肠溶铝塑片进行全谱扫描,建立一致性检验模型,并对图谱进行比对分析。结果:正品氨糖美辛肠溶铝塑片与其伪品存在较大差别,利用一致性检验模型及图谱比对法均可以判断。结论:所用方法快速、简便、准确、有效,是基层查处假冒药品的有效手段。
OBJECTIVE: To quickly identify the authenticity of glucosamine enteric-coated aluminum sheet by near-infrared spectroscopy. Methods: The full spectrum of glucosamine enteric-coated aluminum-plastic sheet was scanned in the range of 4 200 ~ 10 000 cm -1. The consistency test model was established and the comparison of the patterns was carried out. Results: There was a big difference between the genuine aminoglycoside enteric-coated aluminum sheet and its counterfeit goods, which could be judged by using the consistency test model and the mapping method. Conclusion: The method used is quick, easy, accurate and effective and is an effective means to investigate and deal with counterfeit drugs at the grassroots level.
