Background: QishenYiqi dripping pills (QSYQ), consisting of Salvia miltiorrhiza, Astragalus membranaceus, Panax notoginseng, and Dalbergia odorifera, is a widely used to treat ischemic cerebrovascular and hemorrhagic cerebrovascular in China. Objective: In this study, a rapid and sensitive ultra-HPLC coupled with a triple quadrupole MS (UHPLC-QQQ-MS) method was established for the simultaneous quantification of 19 bioactive components. Methods: Chromatographic separation was performed on an Agilent Eclipse Plus C18 Rapid Resolution High Definition (RRHD) column (2.1 × 50 mm, 1.8 μm) with a mobile phase composed of a 0.1% (v/v) formic acid aqueous solution and acetonitrile in a gradient elution manner. A QQQ-MS was used in positive and negative ionization mode with multiple reactions monitoring for quantitative analysis. Results: The established methods were validated with linearity, precision, repeatability, stability, recovery, and matrix effect. All calibration curves exhibited excellent linear relationship with the correlation coefficient (r) >0.9985 for each analyte within the test range. This method was successfully applied to quantify target compounds of different structural types in 12 batches of QSYQ. Conclusions: The results suggest that the established method is rapid, sensitive, and reliable. The developed UHPLC-QQQ-MS method can provide scientific basis and reference to quality control and consistency evaluation of QSYQ sample and other formulations. Highlights: A rapid, sensitive, and reliable UHPLC-QQQ-MS method has been developed and validated for simultaneous determination of 19 compounds including phenolic acids, saponins, isoflavonoids, and tanshinones in QSYQ for the first time.
