Objective: A simple and rapid HPLC method was established for simultaneously determining of paeoniflorin
baicalin and berberine in the mixed decoction of Huanglian Ejiaotang. Method: Agilent TC-C18(4.6 mm×250 mm)chromatographic column
acetonitrile-0.1% phosphoric acid solution gradient elution were applied. Analyses were performed at 35 ℃ with a flowrate of 1.0 mL·min-1 and UV detection at 240 nm
Result: The content of paeoniflorin
baicalin and berberine were 1.64%
7.51%
3.30% respectively. Conclusion: The developed method can be applied to the intrinsic quality control of Huanglian Ejiaotang.
