[Qualitative and quantitative research on nucleosides of Alismatis Rhizoma from different regions].

Ten compounds, including nucleosides and amino acids were identified by UPLC-Q-TOF-MS. HPLC fingerprints on these compounds in Alismatis Rhizoma were established for the first time. The comparisons of Alismatis Rhizoma from different regions were conducted by the similarity evaluation and hierarchical cluster analysis(HCA). Meanwhile, the HPLC-DAD method for the content determination of five nucleosides was also established. The results showed...
