Objective: To establish a method for the determination of thrombolytic capsules. METHODS: The mobile phase was Agilent-C 18 (150 mm × 4.6 mm, 5 μm) with a mobile phase of methanol-water (25:75) at a flow rate of 1.0 ml · min -1 and a detection wavelength of 250 nm The column temperature was 25 ℃. Results: The content of puerarin in thrombolytic capsules was in the range of 0.2136 ~ 1.2816μg with a good linear relationship, r = 0.999 9, the average recovery was 99.91% and the RSD was 1.09%. Conclusion: The method is easy to operate, stable and reliable.
