By comparison with literature data, we proposed that each of them have been twenty ginsenoside Rh1/ginsenoside F1. M8 showed a molecular ion at m/z 798 in MS spectra, and exhibited m/z 717 in MS2 spectra, which was reliable with the fragmentation of salvianolic acid B sulfates. In accordance with all the literature information to the characteristic of MS/MS, M8 was identified as salvianolic acid B sulfates. M9 showed a molecular ion at m/z 783 in MS spectra, and exhibited m/z 621 and 459 in MS2 spectra. The results showed precisely the same fragmentation pathway as being the metabolite of ginsenoside Rb1 and ginsenoside Rd. By comparison with literature data, M9 was recommended as ginsenoside Rg3. Conclusion DPP-4 By analyzing the constituents in rat serum of FTZ depending on UPLC MS procedure and serum pharmacochemistry approach, a approach for rapid evaluation of your likely efficient constituents inside a Chinese Medication formula FTZ have already been established. Within this research, 27 in the prototype constituents and 9 of the metabolites in rat blood following oral administration of FTZ were identified from the UPLC/Q TOF process, which improved the pace and targeting of bioactive constituents examination. These effects indicated that almost all of the alkaloids, ginsenosides, and pentacyclic triterpenes might be observed in rat blood via oral administration of FTZ.
Meanwhile the salvianolic acid cetirizine analogues could be converted into metabolites, this kind of as salvianolic acid B sulfates. Our present do the job to the extensive analysis of the FTZ constituents in rat serum propose that the serum pharmacochemistry study making use of UPLC Q TOF approach offer a fast and reputable tactic for your identification of prospective bioactive compositions for complicated herb prescriptions. Systemic pharmacokinetic investigation from the constituents in rat serum immediately after oral administration of FTZ is warranted for much better comprehension the pharmacokinetic basis of the wellness benefits of FTZ.
