- Abstract: OBJECTIVE: To establish a QTRAP-UPLC-MS/MS method for simultaneous determination of 10 kinds of nucleosides and nucleobases in Scrophulariae Radix processed by different methods, and investigate the influences of different processing methods on contents of nucleosides and nucleobases. METHODS: The contents of 10 kinds of nucleosides and nucleobases in Scrophulariae Radix processed with different methods were simultaneously determined by QTRAP-UPLC-MS/MS, and TOPSIS analysis was used for comprehensive evaluation of nucleosides and nucleobases. RESULTS: The contents of guanosine, uridine, adenosine and uracil were relatively high in Scrophulariae Radix. There were differences in contents of nucleosides and nucleobases of Scrophulariae Radix processed with different methods, and the samples processed by method of "sweating" had better quality. CONCLUSION: This study provides a scientific basis for investigation on the influence of processing methods on contents of nucleosides and nucleobases in Scrophulariae Radix and screening of suitable processing method for Scrophulariae Radix.
