ABSTRACT
The study developed a method for the determination of 14 components in Bazibushen capsule by UPLC-ESI-MS/MS. Waters ACQUITY BEH C18 column (50 mm×2.1 mm, 1.7 μm) was used and the column temperature was 40℃. A linear gradient elution of eluents A (acetonitrile) and B (0.1% acetic acid) was used for the separation. The source temperature was set at 150℃. The capillary voltage was set at 2.0 kV. The source offset voltage was kept at 50 V. The desolvation temperature was set at 500℃. The desolvation flow was 800 L·h-1. The cone flow was 150 L·h-1. The nebuliser pressure was 7.0 Bar. Multiple reaction monitoring mode (MRM) is adopted. All of the 14 components showed good linearity (r2 > 0.999 1) in the test ranges. The LOQs for the compounds ranged from 0.11-4.52 ng·mL-1, respectively. The RSDs were 0.8%-2.1%. The overall recoveries were between 97.89% and 101.9% for all compounds. The method is simple, rapid, accurate and highly reproducible, and may be used in the determination of 14 components in Bazibushen capsule.
