Abstract
DOI: 10.1002/jssc.202001081 The cover picture shows a new HPLC strategy for quantitative analysis of multiple components via a single marker (QAMS) to determine nine nucleosides (cytidine, uridine, 2'‒deoxyuridine, inosine, guanosine, 2'‒deoxyguanosine, thymidine, adenosine and 2'‒deoxyadenosine) in Rhizoma Paridis for the first time. The results of methodology validation showed that there was no significant difference between QAMS method and the external standard method, indicating that QAMS method can applied to solve the problem of a shortage of reference materials and high cost in multicomponent analysis. Our work provide an efficient and feasible quality assessment method for other natural products containing nucleosides.
