Abstract
Objective To develop an identification model of raceanisodamine tablets by diffuse reflection near-infrared spectroscopy and pattern recognition. Methods The diffuse reflectance spectra in the 12 000-4 000 cm-1 spectral coverage range of raceanisodamine tablets from eight different pharmaceutical factories were collected to establish the identification model.A mono-component near infrared model was established for raceanisodamine tablets. Results The parameters of the identification model for the raceanisodamine tablets was as follows:spectral range was 5 400-7 000 cm-1, the pretreatment method was first derivative and normalization; the threshold was 0.603. And the model was validated, which met the requirements of application. Conclusion The results showed that identification model for the raceanisodamine tablets by near infrared spectroscopy was feasible, which provided a reference method for the model updating.
