Rapid discrimination of Notopterygium incisum and Notopterygium franchetii based on characteristic compound profiles detected by UHPLC-QTOF-MS/MS coupled with multivariate analysis.

The UHPLC-QTOF-MS/MS coupled with the multivariate analysis method could discriminate NI and NF from their adulterations. Moreover, the data clearly demonstrated significant differences in the chemical compositions of NI and NF. Further research is needed to examine the relationship between therapeutic efficacy and the chemical constituents of NI and NF.
