Abstract:
To analyze the main components of Qinbai Qingfei concentrated pellets in rat serum with UPLC-Q-TOF-MS technology and serum pharmacochemistry theory. After gavage administration with Qinbai Qingfei concentrated pellets, blood was collected from hepatic portal vein. ACQUITY UPLC BEH C₁₈(2.1 mm×100 mm, 1.7 μm) was used, with 0.1% formic acid agueous solution(A)-0.1%formic acid and acetonitrile(B) as the mobile phase for gradient elution. The flow rate was 0.3 mL•min⁻¹, the column temperature was maintained at 35 ℃. Through the comparative analysis fingerprints of Qinbai Qingfei concentrated pellets, drug containing-serum and blank serum, and with the help Peakview and Metabolitepilot software, components in serum were defined. A total of 28 compounds were identified, including 18 prototypes and 10 metabolites. As a result, UPLC-Q-TOF-MS technology and serum pharmacochemistry theory were applied to comprehensively expound Qinbai Qingfei concentrated pellets'constituents migrating to rat serum, and provide scientific basis for further studies for in vivo metabolic process and effective material base.
