Objective To develop an HPLC method for simultaneous determination of loganic acid, shanzhiside methyl ester, 6'-O-β-D-glucosylgentiopicroside, swertiamarin, gentiopicroside, sweroside, isoorientin, and isovitexin in Jiaolong Capsules. Methods The separation was carried out on Intersil C₁₈ column (250 mm×4.6 mm, 5 μm). The mobile phase was acetonitrile-0.2% phosphoric acid solution with gradient elution. The detection wavelength was set at 254 nm. The volume flow was 0.8 mL/min, the column temperature was 25℃, and the injection volume was 10 μL. Results Loganic acid, shanzhiside methyl ester, 6'-O-β-D-glucosylgentiopicroside, swertiamarin, gentiopicroside, sweroside, isoorientin, and isovitexin showed good linear relationships within the ranges of 21.20-2 120.00, 3.20-320.00, 15.00-1 500.00, 5.10-51.00, 39.00-3 900.00, 4.20-420.00, 2.20-220.00, 1.10-110.00 μg/mL, and their average recoveries were 99.37%, 97.28%, 96.49%, 99.37%, 97.28%, 96.49%, 99.37%, and 97.28% with RSD values of 1.64%, 1.16%, 1.85%, 1.64%, 1.16%, 1.85%, 1.64%, and 1.16%, respectively. Conclusion The method is simple, reproducible, and the results are accurate and reliable, which can provide a reference for further improving the quality evaluation method of Jiaolong Capsules.
