Objective: To study infrared fingerprints of fifteen kinds Astragali Radix from different habitats and grades. Method :Fourier transform infrared spectroscopy(FTIR)combined with second derivative spectra
and Similarity compare software was used to process these spectra. Result: Characteristics and differences between fingerprints were found out. Conclusion: This method is specific
rapid and stable
it could be applied in identification or quality control of Astragali Radix.
