使用本产品的案例(仅供参考

HPLC

Apigenin, scutellarein, scutellarin, and apigenin-7-O-glucuronide were measured at 335 nm using a Kinetex 5 µm Biphenyl 100 Å LC Column (250 × 4.6 mm; Phenomenex, USA) operating at 30 °C. The mobile phase consisted of 0.1% formic acid and acetonitrile with methanol at a flow rate of 1 ml min−1 using the following gradients: 0–20 min, 22% acetonitrile, 5% methanol; 20–22 min, acetonitrile increased from 22 to 90%; 25 min, 22% acetonitrile. Subsequently, the column was washed and equilibrated for 5 min before the next injection. Thirty microliters of the sample were injected into the HPLC system and each run was stopped at 30 min after the injection.

PMID: 29386648; PMCID: PMC5792594.


UPLC-MS

Ultra-performance liquid chromatography-mass spectrometry (UPLC-MS) was performed with liquid mass spectrometer for evaluation. The determination was performed on the SB-C18 column at the flow rate of 0.3 mL/min and the column temperature was 40 ◦C. The flavonoid and anthocyanin components were detected at 210 nm.

UPLC-QTOT-MS

The C18 (2.1 × 100 mm, 1.7 µm) was kept at 30 ℃. The injection volume was 1 µL, and the elution was completed in 18 min with a flow rate of 0.3 mL/min. Solvents A (water + 0.1% formic acid) and B (acetonitrile) were used in the following gradients: 0–2 min (5–10% B), 2–10 min (10–20% B), 10–15 min (20–40% B), 15–17 min (40–70% B), and 17–18 min (70–100% B). The PDA spectra for phenolic compounds were measured at 320 nm and 350 nm. For MS analysis, anthocyanins were analyzed in the positive ion (PI) mode; other phenolic compounds were analyzed in the negative ion (NI) modes. The MS parameters were as follows: source temperature of 120 ℃, desolvation temperature of 250 ℃(400℃ in the positive ion), cone gas flow 50 L/h, desolvation gas flow 600 L/h (800 L/h in the positive ion), source capillary of 3.0 kV. The MS analysis was performed using mass scanning from m/z 50 to 1,500.
