Detection method of liu-wei tonic tablets dual-wavelength fingerprint chromatogram

The invention discloses a quality control method of dual-wavelength overlaying and fusing fingerprints of pills of six ingredients with rehmannia. By combining the technology of fingerprints and the characteristic of components to be detected, utilizing the detecting method that absorption peaks produced by maximum uv-absorption wavelengths of different components overlay and fuse, the invention can eliminate interferences of the absorption peak produced by various wavelengths and ensure the accuracy and reliability of detected components. By the application of dual-wavelength overlaying and fusing, the quality control method correctly grasps the qualities of related medicines, thereby effectively ensuring the safety, unity, stability, efficiency and being controllable of pills of six ingredients with rehmannia. The quality control method of the invention is simple, correct in result and good in reproducibility, and can be applied to the quality evaluation of Chinese medicines, the quality control of Chinese medicines and the new medicine development of Chinese medicines, in particular to being used as one of the indexes of the quality control and true-and-false identification of pills of six ingredients with rehmannia.
