Objective To establish an ultra-performance liquid chromatography-tandem mass spectrometry (UPLCMS/MS) method for simultaneous quantification of 19 saponins in Yixinshu Capsules and evaluate the quality consistency across different batches. Methods Chromatographic separation was performed on a Thermo Fisher Scientific Accucore Phenyl Hexyl column (2.1 mm × 100 mm,2.6 μm) with a mobile phase of 0.1% formic acid in water and acetonitrile under gradient elution. The flow rate was 0.4 mL·min-1 ,and the column temperature was maintained at 35 ℃. A heated electrospray ionization source was utilized in negative ion mode with multiple reaction monitoring (MRM) for quantitative analysis. Batch-to-batch variability of saponins was assessed using multivariate statistical analysis. Results The 19 saponins [notoginsenoside R1, ginsenoside Re, ginsenoside Rg1, ginsenoside Rf, ginsenoside F3,ginsenoside Rg2, ginsenoside Ra2, ginsenoside Rb1, ginsenoside Ro, notoginsenoside Fc, ginsenoside Rc, ginsenoside Ra1,ginsenoside Rb2,ginsenoside Rb3,ginsenoside Rd,notoginsenoside Fe,20(S)-ginsenoside Rg3, 20(R)-ginsenoside Rg3,ginsenoside Rg5] exhibited good linearity (r ≥ 0.998 0) within their respective concentration ranges. Precision,repeatability,and stability tests showed relative standard deviations (RSD)≤ 4.85%,with average recoveries ranging from 97.03% to 100.93% (RSD ≤ 4.87%). All 19 saponins were detected in 10 batches of Yixinshu Capsules, with average contents ranging from 2.67 to 1 110.40 μg·g-1 . Cluster analysis categorized the 10 batches into two groups (Group I: S4, S6, S8, S9, S10; Group II: S1, S2, S3, S5, S7). Orthogonal partial least squares-discriminant analysis (OPLS-DA) identified eight components with variable importance in projection (VIP) values>1—ginsenoside Rb1,Rg1,Rb2,Rg5,Re,Rc,Rd,and Ro—as critical markers for batch differentiation. Conclusion This method enables rapid and accurate quantification of 19 saponins in Yixinshu Capsules,providing a robust technical foundation for enhancing its quality control standards.
