Abstract:
Objective: To establish a rapid, accurate, and practical HPLC method for simultaneous determination the content in Qiju Dihuang Oral Liquid (QDOL) of 5-HMF, morroniside, chlorogenic acid, cryptochlorogenic acid, loganin, paeoniflorin, verbascoside, luteoloside, isochlorogenic acid B, isochlorogenic acid A, isochlorogenic acid C, and paeonol. Methods: YMC ODS column (250 mm × 4.6 mm, 5 μm) was used, column temperature was set at 35 ℃, gradient elution with 0.1% formic acid aqueous solution- acetonitrile was used as mobile phase, flow rate was 1.0 mL/min, detection wavelength was 254 and 325 nm. The injection volume was 10 μL. Results: The injection amount of 5-HMF, morroniside, chlorogenic acid, cryptochlorogenic acid, loganin, paeoniflorin, verbascoside, luteoloside, isochlorogenic acid B, isochlorogenic acid A, isochlorogenic acid C, paeonol injection quality at 0.08—1.60, 0.12—2.40, 0.09—1.80, 0.06—1.20, 0.10—2.00, 0.30—6.00, 0.01—0.20, 0.01—0.20, 0.01—0.20, 0.005—0.10, 0.005—0.10, and 0.01—0.20 μg showed a good linear relationship with peak area, with good precision, repeatability and stability. The recovery rates of the samples were between 96% and 103%, the RSD was 2.13%, 3.45%, 2.86%, 2.59%, 3.15%, 3.49%, 2.19%, 3.25%, 2.37%, 2.53%, 2.91%, and 3.35%, respectively. The content of each component of the five batches of samples was stable, and the mass concentrations range of the 12 components tested were 98.56—102.56, 204.28—212.10, 18.53—18.89, 1.95—2.05, 12.31—12.54, 87.01—87.12, 5.35—5.43, 16.08—16.15, 8.69—8.72, 8.89—8.95, 5.12—5.19, and 1.87—1.94 μg/mL. Conclusion: The method simltaneosly determines the content of 5-HMF, morroniside, chlorogenic acid, cryptochlorogenic acid, loganin, paeoniflorin, verbascoside, luteoloside, isochlorogenic acid B, isochlorogenic acid A, isochlorogenic acid C, and paeonol in QDOL, which is suitable for the quality control of QDOL.
