Abstract: Objective To analyze chemical constituents of Pueraria lobata by ultrahigh pressure liquid chromatography-quadrupole-time of flight mass spectrometry (UHPLC-Q-TOFMS). Methods A ACQUITY UPLC HSS T3 (100 mm×2.1 mm, 1.8 μm) column was used to separate. The mobile phase consisted of water containing 0.1% methane acid and acetonitrile was used as gradient elute. The flow rate was 0.4 ml/min. TOFMS was applied for qualitative analysis under positive ion mode. Results Under optimized condition, 19 major constituents in Gardenia jasminoides Ellis were identified by quadrupole-time of flight mass spectrometry and structure-relevant fragment ions. Conclusion A simple and reliable method using UHPLC-Q-TOFMS was established to identify the chemical constituents of Pueraria lobata.
