Document: A UPLC-qTOF-MS system (Synapt, Waters, USA, equipped with MassLynx acquisition software, version 4.1) was used and experimental conditions were column, C18 (50 mm  2.1 mm); particle size, 1.7 mm (Acquity, BEH); flow rate, 200 mL/min; mobile phase, acetonitrile:2% acetic acid in water (75:25, v/v); injection volume, 1 mL. The analyte infusion experiments were performed using an in-built syringe pump. A UPLC-qTOF-MS with ESI interface was used for MS/MS analysis. ESI parameters were capillary voltage, 2.7 kV for positive mode; source temperature, 100 1C; desolvation temperature, 200 1C; cone gas flow, 50 L/h and desolvation gas flow, 550 L/h. The multiple reaction monitoring (MRM) mode was used to monitor the transitions
