FT-IR spectroscopy in quality control of the processing techniques of Radix Rehmanniae Preparata with millet wine / 中成药

AIM: To study the process of Radix Rehmannia Preparata and find “the proper processing end point”, then standardize the slice. METHODS: Monolithic surveillance to the process and analyzing the change of the characteristic peaks between dried Radix Rehmannia and Radix Rehmannia Preparata by FT IR spectroscopy. RESULTS: We can know the dynamic change in Radix Rehmannia Preparata during the convenient processing course by the FT IR spectroscopy. CONCLUSION:FT IR is a powerful measure to standardize processing techniques, standardize the slice on the base of traditional processing experiences.
