Abstract:
To characterize the chemical constituents of Huanbei Zhike Prescription by ultra-high performance liquid chromatography-time of flight mass spectrometry( UPLC-Q-TOF-MS/MS). A Thermo Syncronls C18 column( 2. 1 mm×100 mm,1. 7 μm) was used with methanol( A)-0. 1% formic acid solution( B) as the mobile phase for gradient elution. The injection volume was 2 μL; the column temperature was 40 ℃; the flow rate was 0. 3 m L·min-1; and electrospray ionization( ESI) source was used to collect data in positive and negative ion modes. The ion scanning range was m/z 50-1 200,with capillary voltage of 3 000 V,ion source temperature of100 ℃,atomization gas flow rate of 50 L·h-1,desolvent gas flow rate of 800 L·h-1,desolvent temperature of 400 ℃,cone hole voltage of 40 V,with argon as the collision gas and the collision energy was 20-35 V. The excimer ion peak information was analyzed by Waters UNIFI data processing software. The molecular formula with error within 1×10-5 was compared with the data in database to identify the compounds. The secondary fragment ion information of the target compound was selected,and then compared with the retention time and fragmentation patterns provided by the database and the existing literature to further confirm the compositions and structures of the compounds. A total of 68 main compounds in Huanbei Zhike Prescription were identified,including 38 flavonoids,10 organic acids,6 terpenoids and 10 nitrogen-containing compounds,of which 12 compounds were verified by the control substances. This method is rapid and accurate,which provides a new strategy for the qualitative analysis of the chemical constituents of Huanbei Zhike Prescription,and lays a foundation for the further study and quality control of the compound pharmacodynamic substance.
