Objective An HPLC method was established for determining four constituents (verbascoside, loganin, paeoniflorin, and paeonolum ) in Liuwei Dihuang Capsule. Methods HPLC-gradient elution method was applied. The column was Kromasil C₁₈ (250 mm × 4.6 mm, 5 μm). The mobile phase was 1% acetic acid solution (A) and acetonitrile (B). The detection wavelength was set at 245 nm. Results The linear range of density was 6—60 μg/mL for verbascoside, 15—150 μg/mL for loganin, 50—500 μg/mL for paeonolum, and 5—50 μg/mL for paeoniflorin, respectively. The correlation coefficient of all curves were better than 0.999. The average recoveries of four analytes were 98.3% for verbascoside, 99.3% for loganin, 99.0% for paeonolum, and 99.0% for paeoniflorin, and the RSD values were less than 0.9% (n = 9). Conclusion The developed HPLC method could be used for the quality control of Liuwei Dihuang Capsule.
