OBJECTIVE: To establish HPLC fingerprint of Miao medicine Hedyotis uncinella from Guizhou. METHODS: HPLC method was adopted. The determination was performed on Agilent Eclipse XDB C18 column with mobile phase consisted of acetonitrile-0.2% phosphoric acid (gradient elution) at the flow rate of 1.0 mL/min. The detection wavelength was set at 235 nm, and column temperature was 25 ℃. The sample size was 15 μL. Using rutin as reference, HPLC chromatograms of 10 batches of H. uncinella from different areas of Guizhou province were determined. Similarity Evaluation System for TCM Chromatographic Fingerprints (2004A edition) was used to identify common peaks and evaluate similarity. RESULTS: There were 12 common peaks in HPLC fingerprints of 10 batches of H. uncinella, and the similarity was higher than 0.90. After validation, HPLC chromatograms of 10 batches of sample were in agreement with control fingerprints. CONCLUSIONS: Established HPLC fingerprints can provide reference for the identification and quality evaluation of H. uncinella.
