Simultaneous Determination of Eight Bioactive Constituents in Shensong Yangxin Capsule by UPLC

ObjectiveTo develop a ultra performance liquid chromatography (UPLC) method for the quality evaluation of Shensong Yangxin Capsule (SYC).MethodsThe Waters Acquity UPLC HSS T3 column (100 mm × 2.1 mm, 1.8 μm) was used. Acetonitrile and water containing 0.1% phosphoric acid were used as mobile phases of UPLC with gradient elution. The detection wavelengths were set at 203 (ginsenoside Rb1), 286 (salvianolic acid B), 230 (paeoniflorin), 221 (schisantherin A), 280 (sodium danshensu), 327 (chlorognenic acid), 335 (spinosin), and 345 nm (berberine hydrochloride), respectively. The flow rate was set at 0.4 mL/min and column temperature was 35 °C.ResultsThe contents of paeoniflorin, salvianolic acid B, schisantherin A, sodium danshensu, chlorognenic acid, spinosin, berberine hydrochloride, and ginsenoside Rb1 were determined from 10 batches of SYC.ConclusionThe method of the quality evaluation of SYC has acceptable precision, reproducibility, and stability, which could be used as a new method for the quality control of SYC.
