    Abstract:
    OBJECTIVE: To establish the fingerprint of Maodongqing injection by HPLC. METHODS: The column of ODS-2 Hypersil C18 (4.6 mm x 200 mm, 5 microm) was used. The mobile phase consisted of acetonitrile-0.05% phosphoric acid with gradient elution. The flow rate was 1 mL/min, the column temperature was 30 degrees C, and the detection wavelength was 325 nm. RESULTS: The fingerprint of Maodongqing injection was established, and 8 samples of different batches of Maodongqing injection were detected. Thirteen peaks in the chromatogram were marked by "Similarity Evaluation System for Chromatographic Fingerprints of Traditional Chinese Medicine (Version 2004 A)". There was a high similarity and each chromatographic peak was obtained with good separation and correlation according to the technical requirements of the fingerprints of Chinese traditional medicine. CONCLUSION: This method is accurate, reliable and provides a scientific basis for controlling the quality of Maodongqing injection.
