Rapid identification of chemical constituents in serum and plasma of Fuzheng Huayu capsules by UHPLC-TOF/MS / 药学实践杂志

ABSTRACT

Objective To identify the blood components of Fuzheng Huayu capsule by ultra performance liquid chromatography-high resolution time-of-flight mass spectrometry (UHPLC-Q-TOF/MS). Methods ACQUITY UPLCHSS T3 (2.1 mm × 100 mm, 1.8 μm) was used to chromatographic separation; mobile phase was 0.1% formic acid aqueous solution (A) −0.1% formic acid acetonitrile solution (B). The gradient elution conditions included 0−3 min, 2% B; 3−18 min, 2%−50% B; 18−22 min, 50%−95% B; 22−25 min, 95% B. The equilibration time was 10 min, the flow rate was 0.40 ml/min, and the analysis time was 25 min. The mass spectrometry was characterized by electrospray ionization by a positive-negative ion mode scan with a range of 100-1 100 m/z. Results 49 components were identified in the serum samples at one time, of which 4 were positive and negative ion modes. Conclusion The blood components of Fuzheng Huayu capsule were clarified by this method, which enriched the scientific connotation of Fuzheng Huayu capsule, and laid the foundation for the in-depth study of the compound.
