Objective: To develop an UPLC method of determining the characteristic chromatographic profile of Lonicera japonica for controlling the drug quality quickly and accurately. Method: The analysis was performed on an Agilent C18 column(2.1 mm×50 mm
1.8 μm) with acetonitrile-0.2% phosphoric acid as mobile phase in gradient elution mode. The flow rate was 0.4 mL·min-1 and the injection volume was 2.0 μL with the detection wavelength of 238 nm.The column temperature was set at 30 ℃. Result: The fingerprint of Lonicera japonica was obtained within 21 min and five peaks in the fingerprint were designed.14 samples were analyzedand the similarities were 0.915-0.987. Conclusion: The UPLC system enjoys the merits of a higher speed
sensitivity
and resolution
it can be used to control the quality of L. japonica.
