| ［Abstract］ Objective To establish a conformity test model for inspecting tenofovir disoproxil fumarate tablets by near-infrared reflectance spectroscopy(NIRS).Methods The method of first derivative（FD） and vector normalization(SNV) was employed to pretreat the corresponding near spectroscopy spectral of tenofovir disoproxil fumarate tablets with the spectral ranges of 12 000～4 000 cm-1, the optimum modeling band of 9 000～7 500 cm-1, 6 900～5 600 cm-1 and 5 000～4 250 cm-1, the smoothing point of 17 and CI being 7. The conformity test model was constructed on the basis of the above parameters and was validated.Results Using the conformity test model can distinguish the authentic from the inauthentic tenofovir disoproxil fumarate tablets by different inspectors and near-infrared instruments.Conclusion The conformity test model is simple, accurate, feasible and suitable for the drug examination of tenofovir disoproxil fumarate tablets. |
