Objective:To establish an HPLC fingerprint of Aurantii Fructus Praeparatus dispensing granules and provide experimental evidence for its quality criteria. Method: Take methanol extract of Aurantii Fructus Praeparatus dispensing granules as sample by ultrasonic processing

HPLC analysis was carried out on Hypersil C18(1.6 mm×200 mm

5 μm) chromatographic column with mobile phase of methanol (A)-0.1% glacial acetic acid (B)

gradient elution with a flow at 1.0 mL·min-1

an ultraviolet detection wavelength at 320 nm and column temperature at 30 ℃. Result: Eight common peaks and three characteristic peaks were identified in chromatograms from ten batches of samples. The similarity is above 0.9 in different batches of samples with the peak of naringin as reference. Conclusion: The method is accurate

credible with good repeatability; it can provide reference evidence for quality control of Aurantii Fructus Praeparatus dispensing granules.
