Analysis of Chemical Constituents in Puerariae Lobatae Radix Dispensing Granules by UPLC-Q-TOF-MS/MS增强出版
A rapid method for identification of chemical constituents in Puerariae Lobatae Radix dispensing granules was established in order to clarify the material basis.
Method
2
The chemical constituents of Puerariae Lobatae Radix dispensing granules was qualitatively analyzed by ultra-performance liquid chromatography-quadrupole-time-of-flight mass spectrometry(UPLC-Q-TOF-MS/MS) under positive and negative ion modes, and the chromatographic conditions were on an ACQUITY UPLC HSS T3 column(2.1 mm×100 mm, 1.8 μm) with 0.1% formic acid aqueous solution(A)-0.1% formic acid acetonitrile solution(B) as mobile phase for gradient elution(0-4 min, 5%-10%B; 4-10 min, 10%-15%B; 10-20 min, 15%-16%B; 20-27 min, 16%-31%B; 27-33 min, 31%-59%B; 33-42 min, 59%-95%B; 42-42.1 min, 95%-5%B; 42.1-45 min, 5%B), the flow rate was 0.35 mL·min

, the column temperature was 40 ℃, the injection volume was 5 μL, and electrospray ionization(ESI) was selected. Then these chemical constituents were comprehensively identified based on PeakView 1.2, PubChem, ChemicalBook, ChemSpider, comparative control profiles and literature information.
Result
2
A total of 128 chemical constituents were identified from the dispensing granules, including 60 flavonoids, 26 organic acids, 7 glycosides, 6 coumarins, 3 nucleosides and 26 other compounds. By focusing on the cleavage patterns of flavonoids, organic acids, glycosides, coumarins, nucleosides and other compounds, 12 compounds that have not been reported in Puerariae Lobatae Radix species were identified from the dispensing granules.
Conclusion
2
The established method can systematically and rapidly identify the chemical constituents in Puerariae Lobatae Radix dispensing granules, and cleared it composition is mainly flavonoids and organic acids. Laying a foundation for the study of the material basis, mechanism of action and clinical application of the dispensing granules.
