UPLC–ESI–QTOF MS/MS

The samples were separated on a Zorbax SB-C18 column (3.5 μm, 100 mm × 2.1 mm i.d.). The mobile phase was a stepwise gradient of 0.1% formic acid aqueous solution (A) andmethanol (B) as follows: 10% B at 0–3 min; 10–65% B at 3–10 min; 65–80% B at 10–10.5 min and maintained at 80% B from 10.5 min to 15 min. The UV wavelength was set at 254 nm. The column temperature and the flow rate were set at 20 °C and 0.2 mL/min, respectively.The UPLC system was connected to an Agilent 6530 QTOF mass spectrometer (Santa Clara, CA, USA) equipped with a dual electrospray ionization (ESI) interface using the following operation parameters: capillary voltage, 3.5 kV in (−)ESI mode or 4.0 kV in (+)ESI mode; nebuliser, 40 psig; drying gas (nitrogen) flow rate, 10.0 L/min; gas temperature, 325 °C; fragmentor, 175 V; skimmer voltage, 65 V; OCT 1 RF Vpp, 750 V. Mass spectra were recorded across the range m/z 100–1500.

UPLC–QTOF MS/MS

UPLC analysis was performed on an Infinity LC instrument consisting of a quaternary pump, an auto-sampler, a column compartment and a diode-array detector. The samples were separated on a C18 column (3.5 μm,100 mm × 2.1 mm i.d.). The mobile phase was a stepwise gradient of water (A)and methanol (B).as follows: 10% B at 0–3 min; 10–65% B at 3–10 min; 65–80% B at 10–10.5 min and maintained at 80% B from 10.5 min to 15 min. The UV wavelength was set at 254 nm. The column temperature and the flow rate were set at 20 ℃ and 0.2 mL/min, respectively. The UPLC system was connected to QTOF mass spectrometer equipped with a dual electrospray ionization (ESI) interface using the following operation parameters: capillary voltage, 3.5 kV in (−)ESI mode or 4.0 kV in (+)ESI mode; nebuliser, 40 psig; drying gas (nitrogen) flow rate, 10.0 L/min; gas temperature, 325 ℃; fragmentor, 175 V; skimmer voltage, 65 V; OCT 1 RF Vpp, 750 V. Mass spectra were recorded across the range m/z 100–1500. The MS/MS collision energy was set at 20–30 V.
