A total of 12 common fingerprint peaks were designated in ZSS and ZMS, respectively, and five of which were definitely identified. Of these common peaks, 10 peaks were presented in both ZSS and ZMS, whereas two were characteristic for ZSS and ZMS, respectively. Furthermore, the two characteristic peaks of ZMS were definitely assigned as 6′′′-sinapoylspinosin and frangufoline by HPLC guided purification and structural elucidation. The HPLC fingerprint analysis was proved to be useful in identifying and discriminating ZSS and ZMS, which was beneficial for quality control of ZSS and its products.展开更多
