Objective To establish an effective UPLC-TQ-MS method for the simultaneous determination of 12 components (shikimic acid, chlorogenic acid, isochlorogenic acid B, isochlorogenic acid C, protopine, allocryptopine, tetrahydropalmatine, corydaline, palmatine, quercetin, isotoosendanin, and toosendanin) in Jinhong Tablets (金红片, JHT). Methods The chromatographic separation was performed on an Acquity UPLC BEH C₁₈ column (100 mm×2.1 mm, 1.7 μm) with a gradient elution of acetonitrile (0.1% formic acid) and water (0.1% formic acid), and the flow rate was set at 0.3 mL/min; Multiple reaction monitoring (MRM) mode was used for the quantification of 12 components. Results The 12 components were accurately quantified within 17 min, and the linear ranges of 12 quantitation components were 50.00—6 400.00 μg/mL (r = 0.999 1), 2.28—292.00 μg/mL (r = 0.999 9), 0.82—104.80 μg/mL (r = 0.999 8), 1.56—200.00 μg/mL (r = 0.999 7), 0.91—116.00 μg/mL (r = 0.999 0), 0.94—120.00 μg/mL (r = 0.999 0), 9.38—1 200.00 μg/mL (r = 0.997 4), 2.93—375.00 μg/mL (r = 0.999 0), 1.25—160.00 μg/mL (r = 0.999 9), 31.25—4 000.00 μg/mL (r = 0.999 7), 0.93—120.90 μg/mL (r = 0.999 8) and 1.41—180.70 μg/mL (r = 0.999 7). And the average recoveries were 101.9%, 101.2%, 97.9%, 96.8%, 100.8%, 100.1%, 108.7%, 100.0%, 99.2%, 102.0%, 99.0% and 103.2%, respectively. The contents of 15 batches of the 12 major components were in the ranges of 10.11—22.72 mg/g, 0.16—0.43 mg/g, 0.06—0.23 mg/g, 0.13—0.42 mg/g, 0.08—0.26 mg/g, 0.08—0.25 mg/g, 1.94—2.59 mg/g, 0.20—0.96 mg/g, 0.07—0.30 mg/g, 1.72—2.14 mg/g, 0.03—0.06 mg/g and 0.03—0.06 mg/g, respectively. Conclusion The multi-index components quantitative analysis method established by UPLC-TQ-MS is simple, sensitive and specific, it can be applied for the detection of ingredients with different structures, and provides a solid basis for overall quality control of JHT.
