Objective To develop an HPLC method for the simultaneous determination of paeoniflorin, liquiritin, magnolol, ferulic acid, hesperidin, costunolide, dehydrocostus lactone, synephrine, baicalin, and berberine in Xianglian Huazhi Pill. Methods The chromatographic separation was achieved on a Waters Symmetry-C18 (150 mm × 4.6 mm, 3.5 μm) column with methanol- acetonitrile-waters (50:45:5, A) and methanol-0.1% phosphoric acid (4:96, B) as mobile phases for gradient elution, at the flow rate of 1.0 mL/min; The column temperature was 45 ℃. Results The results showed that the ten active components were well separated and showed good linearity, paeoniflorin (1.5-15.0 μg/mL), liquiritin (0.5-5.0 μg/mL), magnolol (1.0-10.0 μg/mL), ferulic acid (0.5-5.0 μg/mL), hesperidin (12.5-125.0 μg/mL), costunolide (2.5-25.0 μg/mL), dehydrocostus lactone (2.5-25.0 μg/mL), synephrine (0.75-7.5 μg/mL), baicalin (1.5-15.0 μg/mL), and berberine (0.75-7.5 μg/mL). The precision was good and RSD was less than 2.0%. The repeatability was good, and RSD was less than 2.0%. The stability was good in 12 h. The average recoveries were between 98.5%-101.4%, and RSD was less than 2.0%. Conclusion The method is accurate, sensitive, credible, and repeatable. It can be applied to the quality control of Xianglian Huazhi Pill.
