【Abstract】 Objective: To establish the UPLC fingerprint of Compound Lonicera Granules and determine the contents of three main components, and provides some reference for the quality control of Compound Lonicera Granules. Methods: The separation was performed on Acquity UPLC BEH C18(2.1 mm×100 mm, 1.7 μm) column gradient eluted with the mobile phase consisting methanol and 0.1% phosphoric acid water in gradient mode.The flow rate was 0.30 mL/min and the column temperature was 30 ℃. The detection wavelength was set at 320 nm. Results: The UPLC fingerprint of 15 batches of Compound Lonicera Granules were established and it had16 characteristic common peaks. The contents of three components of chlorogenic acid, baicalin and forsythin were determined. The similarity degrees of 15 batches of the sample were more than 0.97. The 15 batches of sample were classified into two categories through pattern recognition. Chlorogenic acid, baicalin and phillyrin showed a good linearity in 18-180 μg/mL,10-100 μg/mL and 21-210 μg/mL, respectively. The average recoveries were 97.95%-99.26%. Conclusion: The method is stable and reliable, and can be used for the quality control and evaluation of Compound Lonicera Granules.更多还原
