注射用單磷酸阿糖腺苷近紅外快速定量方法的建立
[Abstract]:Aim: to establish a rapid quantitative analysis method of adenosine arabinoside monophosphate for injection by near infrared spectroscopy (NIR) and chemometrics. Methods: 133 batches of adenosine arabinoside monophosphate (AMP) for injection from 17 factories were used as the analysis object, 68 batches were used as calibration set, and the content range was 46.79 batches and 97.25 batches as the verification set, and the content range was 47.89 batches as well as 94.49 batches. The near infrared diffuse reflectance spectra of the samples were first collected, and the content of the samples was determined according to the legal standard. Finally, the partial least square method was used to establish a quantitative model. Results: external validation was used to establish the model. The spectral bands of modeling are 7 502.3n 6 098.2 cm~ (-1) and 5 450.2 cm~ (-1) 4 597.8 cm~ (-1), the pretreatment method is first order derivative and multivariate scattering correction, the dimension is 7; The determination coefficient of internal cross validation is 96.82, the root mean square error is 2.64; the external validation decision coefficient is 97.54; the root mean square error is 2.29. Conclusion: the established quantitative model can be used for accurate rapid quantitative analysis of adenosine arabinoside monophosphate for injection green and environmental protection and can be used for rapid analysis and testing of drugs.
