Objective To establish qualitative and quantitative analysis methods for identification and determination of multi-constituent of Chanfukang granules (CFKG) using high performance liquid chromatography-time-of-flight mass spectrometry (HPLC-TOF-MS) and high performance liquid chromatography-triple quadrupole mass spectrometry (HPLC-MS/MS), and a preliminary pharmacokinetic study was carried out. Methods An Agilent ZORBAX Eclipse Plus C₁₈ column (100 mm×3.0 mm, 1.8 μm) and a Waters XBridge^® BEH C₁₈ column (150 mm×4.6 mm, 2.5 μm) were used with 0.1% formic acid aqueous solution-acetonitrile as mobile phases by gradient elution. The compounds were detected by electrospray ion source in both positive and negative mode with multiple reaction monitoring (MRM) mode. SD rats were ig with CFKG (0.5, 5 g/kg). Blood samples of 0.2 mL were taken from jugular vein at different time points and plasma components and contents were determined by HPLC-MS/MS. Results Twenty-four constituents were identified by HPLC-TOF-MS qualitative analysis and thirteen constituents were quantitatively detected by HPLC-MS/MS. The established HPLC-MS/MS method had a good separation, and all the legal verification met the requirements. The content of stachydrine, Leonurine, and astragaloside IV were high, which may be the main active ingredient. The pharmacokinetic results showed that, only when the dose was 5 mg/kg, stachydrine and Leonurine can detected. Elimination of stachydrine was slow and elimination of Leonurine was fast. Conclusion A rapid and efficient method for studying the chemical constituents was established, which could provide reference for the quality control of Chanfukang granules.
