Objective: To established the method of Yinhuang series preparations fingerprint chromatogram. Method: In this method
the C18 column (4.6 mm×150 mm
5 μm) was used
and acetonitrile-0.1% phosphoric acid was used as gradient eluent; detection wavelength was at 318 nm. Result: Yinhuang capsules
Yinhuang buccal tablets
Yinhuang granules and Yinhuang oral liquid were consistent with the overall fingerprint chromatogram
but the number and percentage of common peaks slightly different
10 batches similarity of Yinhuang series preparations are greater than 0.9. Conclusion: This method is useful for quality control of Yinhuang series preparations.
