Objective： To establish a rapid near-infrared spectroscopy identification method for Dens Draconis and its adulterants. Methods： Analyzed the Chemical composition of Dens Draconis and its adulterant by IR, established near-infrared spectral clustering analysis model. The accuracy of the model was verified. Results： Dens Draconis and its adulterant had different characteristic absorption peaks in the infrared spectral region, and the adulterants had more peaks information. On this basis, the near-infrared spectral clustering model was established successfully. Conclusion： IR is suitable to verify chemical composition of Dens Draconis. Dens Draconis and its adulterants could be quickly and accurately identified by the near-infrared spectral clustering analysis model.
