Q-TRAP-LC-MS/MS analysis on nucleosides in Pseudostellariae Radix with different processing methods / 中草药

ABSTRACT

Objective: To investigate the influence of different processing methods on the contents of nucleosides in Pseudostellariae Radix (PR). Methods: Q-TRAP-LC-MS/MS method was applied for the analysis on 13 kinds of nucleosides in PR with different processing methods. Results: The contents of cytidine, uridine, inosine, guanosine, and thymidine were higher in PR. The different processing methods of PR had certain influence on the contents of nucleosides. The amount of nucleosides in PR by oven drying was higher than that by drying in the sun. Conclusion: The paper investigates the influence of processing methods on chemical composition in PR, and provides the basis for establishing reasonable processing technology.
