Objective To develop an HPLC method for determination of sythoside B, forsythoside A, forsythin, deapi-platycoside E, platycoside E, platycodin D₃, arteannuin B, and artemisinic acid in Ergan Tuirining Oral Liquid. Methods The separation was performed on an Agilent TC-C₁₈ column (250 mm×4.6 mm, 5 μm) with the mobile phase consisted of acetonitrile and 0.2% phosphoric acid solution for gradient elution. The detection wavelength were set at 275 nm for forsythoside B, forsythoside A, and forsythin, and 210 nm for deapi-platycoside E, platycoside E, platycodin D₃, arteannuin B, and artemisinic acid. The column temperature was set at 25 ℃, and the flow rate was 0.9 mL/min with injection of 10 μL. Results Forsythoside B, forsythoside A, forsythin, deapi- platycoside E, platycoside E, platycodin D₃, arteannuin B, and artemisinic acid showed good linear relationships in the ranges of 3.47 — 69.40 μg/mL (r=0.999 5), 18.78 — 375.60 μg/mL (r=0.999 2), 6.64 — 132.80 μg/mL (r=0.999 7), 2.57 — 51.40 μg/mL (r=0.999 5), 4.86 — 97.20 μg/mL (r=0.999 3),4.23 — 84.60 μg/mL (r=0.999 8), 0.79 — 15.80 μg/mL (r=0.999 1), 2.16 — 43.20 μg/mL (r==0.999 9). Their average recoveries (RSDs) were 98.76% (1.53%), 100.12% (0.89%), 99.34% (0.91%), 97.57% (1.38%), 98.29% (1.02%), 99.25% (0.83%), 96.87% (1.26%), and 98.02% (1.15%), respectively. Conclusion The HPLC method is accurate which can be used for the quality control of Ergan Tuirining Oral Liquid.
