LC-MS

For HILIC separation, samples were injected onto an column (2.1 ×100 mm, 1.7 µm;) at 25 ℃, and using a 21.2 min linear gradient at 0.3 mL/min flow rate and 2 µL injection volume. ESI source conditions were set as follows: curtain gas (CUR) as 30, ion source gas1 (GS1) as 60, and ion source gas2 (GS2);source gas temperature as 600℃;ISVF as 5500 V. The MS/MS acquisition was performed in positive (PI) and negative ion (NI) modes, the mass range was set at 25-1000 m/z, and the accumulation time for product ion scan was set at 0.05 s/spectrum.

The second order spectrum was acquired in information-dependent acquisition (IDA) and high-sensitivity modes. Parameters were set as follows: declustering potential (DP) as±60 V;collision energy as 35 V±15 eV;maximum candidate ions to monitor per cycle as 10;excluding isotopes within 4 Da.

LC-MS/MS

LC-MS/MS conditions Analysis was performed using a liquid chromatographytandem mass spectrometer LC–MS/MS equipped with an ESI source. Separation was performed using a C18 column (250 mm × 4.6 mm × 5 μm). The flow rate was 0.4 ml/min, and the column temperature was maintained at 25℃. The mobile phases were formic acid: water (0.1:100, v/v) as mobile phase A, and methanol:acetonitrile (1:1) and 0.1% formic acid as mobile phase B. The binary gradient elution conditions were: (A:B): 0.01 min–5 min, 70:30→5:95;5–8 min, 5:95;8.01 min–16 min, 70:30. Detection was performed using multiple reaction monitoring (MRM) in positive mode, and the optimized MRM parameters for each compound are shown in Table 1. The mass condition parameters were set as: nebulizer gas, 3 L/min;drying gas, 10.0 L/min;heating gas, 10.0 L/min;interface temperature, 30℃;collision-induced dissociation (CID) gas, 230 kPa;DL temperature, 250℃;thermal block temperature, 400℃;interface voltage, −4.5 kV. The autosampler was kept at 4℃.
