Objective: To establish a UPLC method for the determination of fingerprint chromatograms of Tongxinluo capsules
help its quality control and evaluate its internal quality. Method: A Waters ACQUIT UPLC® BEH C18column (2.1 mm×100 mm
1.7 μm) was used and acetonitrile-0.2% phosphoric acid solution as mobile phase at the flow rate of 0.45 mL·min-1with gradient elution;the detection wavelength was set at 203 nm;the column temperature was maintained at 30 ℃. Result: An UPLC method for the determination of fingerprint chromatograms of Tongxinluo capsules was established. It showed 39 common peaks and the similarity threshod was 0.96. Conclusion: The method was proved accurate and repeatable. It can be applied to the quality control of Tongxinluo capsules.
