Objective Ultra performance liquid chromatography tandem quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF-MS) was adopted to rapidly characterize the chemical constituents from standard decoction of Ginseng Dispensing Granules, elucidate the chemical basis of Ginseng Dispensing Granules, and establish an HPLC fingerprint for their quality control. Methods An ACQUITY UPLC HSS T3 (100 mm×2.1 mm, 1.8 μm) column was used for the gradient elution with acetonitrile (A)-0.1% formic acid (B) as the mobile phases, and the data was collected in positive and negative modes. The chemical constituents of Ginseng Dispensing Granules were analyzed and identified by MS DIAL software, comparing with reference standards and searching database. The HPLC fingerprint was established on an ACQUITY UPLC HSS T3 column (2.1 mm×150 mm, 1.8 μm) with acetonitrile −0.01% phosphoric acid as the mobile phases. Results A total of 57 compounds, including 25 saponins, 12 amino acids and their derivatives, five bases and nucleosides, together with 15 other compounds, were identified in the standard decoction of Ginseng Dispensing Granules. The HPLC fingerprint of Ginseng Dispensing Granules was established with eight common peaks, respectively ginsenoside Rg1, ginsenoside Re, ginsenoside Rf, ginsenoside Rc, ginsenoside Ro, ginsenoside Rb1, ginsenoside Rb2, and ginsenosede Rd. And the precision, stability and reproducibility of the HPLC fingerprint were acceptable. The components in different batches of Ginseng Dispensing Granules from different manufacturers were basically similar, and only slight differences existed in contents. Conclusion The results of this study clarified the chemical substance basis of Ginseng Dispensing Granules, and the established HPLC fingerprint provided a method reference for the quality control of Ginseng Dispensing Granules.
