Abstract

Objective To establish the fingerprint of Forsythia suspensa dispensing granule by HPLC. Methods The total of 10 samples of Forsythia suspensa were analyzed by HPLC on a Waters SunFire C18 column(4. 6 mm×250 mm,5 μm) with mobile phase of A:acetonitrile and mobile phase B:0. 4% acetic acid solution as gradient elution, with flow rate at 1. 0 mL·min-1 , wavelength at 277 nm and column temperature at 30 ℃. Results There were 13 characteristic common peaks in the Forsythia suspensa dispensing granule, in which two peaks identified as forsythoside A and forsythin, the similarities were more than 0. 999. Conclusion The HPLC fingerprint of Forsythia suspensa dispensing granule is stable, and is easy to manipulate, which can provide more information for the quality control of Forsythia suspensa dispensing granule.
