Abstract: To establish an analytical method for quickly identifying the authenticity of medicinal pearl powder. Method: Diffuse Reflectance Infrared Spectroscopy (Diffuse Reflectance)
Fourier Transform Infrared Spectroscopy for short: DR-FTIR). RESULTS: Compared with the infrared spectrum of common fake pearl powder, the infrared spectrum of medicinal pearl powder has obvious characteristics and uniqueness. Conclusion: DR--FTIR can be used to characterize and identify the authenticity of medicinal pearl powder. The preparation of samples does not require chemical treatment, and the analytical method is simple.
Key words: diffuse reflectance Fourier transform infrared spectroscopy; pearl powder; identification
