Objective: To establish a RP-HPLC method to determine the content of aesculetin in Qingre Kasen Keli. Method: The RP-HPLC method was used.The analytical column was KromasilMC18 (4.6 mm×250 mm
5 μm)
The mobile phase was acetonitrile-0.1% phosphoric acid (10 ∶90).The flow rate was 1.0 mL ·min-1.The detector wavelength was at 346 nm;injection volume was 10 μL. Result: The linear range was within 0.010 1-0.253 2 μg (r=0.999 9).The average recovery was 99.1% (RSD 1.14%). Conclusion: The method is simple
accurate and sensitive
and can be used for quality control of Qingre Kasen Keli.
