HPLC

About 5 µL of the diluted AVTE sample solution was analyzed using an HPLC System and separated using an C18 column (2.6 µm, 4.6 × 150 mm). Mobile phase A was water containing 0.5% acetic acid, and mobile phase B was acetonitrile. The flow rate was 0.5 mL/min with a column temperature of 30℃, and the detection wavelength was 328 nm. The gradient elution conditions were as follows: Equilibrium stage was set for 10 min with 12% B (isocratic) then, 0–30 min with 12%–45% B (linear gradient), 30–35 min with 45%–100% B (linear gradient), and 35–40 min with 100% B (isocratic).

UHPLC

Chromatographic separation of SPLFA and SPLF was done on an Agilent 1290 UHPLC system  coupled to an auto sampler, a diode array detector (DAD) and an ACQUITY UHPLC® HSS T3 column (2.1 ×100 mm, 1.8 μm; Waters, Milford, MA, USA)maintained at 30 ◦C. Eluent A was 0.05% formic acid in water and eluent B was 0.05% formic acid in acetonitrile. Elution of the SPLPA compounds was achieved using the following linear gradient elution (in %B): 0 min, 5%; 20 min, 60%; 20.1 min, 5%; 30 min, 5%, and for the SPLF compounds: 0 min, 20%, 25 min, 50%, 25.1 min, 20%, 35 min, 20%. The injection volume was 5 μL, with a flow rate of 0.3 mL/ min. All sample solutions were filtered through a 0.22 μm PTFE filter (Agilent Technologies) before analysis. The detection wavelength was 320 nm for SPLPA and 254 nm for SPLF.

HPLC

The phenolic acid contents were also measured usingHigh Performance Liquid Chromatography.Chromatographic separation was conductedwith an C18 column (4.6 mm × 250 mm,5 mm) and a binary solvent system of (A) methanol (0.1%H3PO4) and (B) water (0.1% H3PO4). The elution wasperformed at a flow rate of 1.0 mL/min and the columntemperature was maintained at 30℃. The contents of phenolicacids [CGA, neochlorogenic acid (NCGA), cryptochlorogenicacid (CCGA), p-coumaryl quinic acid, and caffeoyl shikimicacid] were detected at 320 nm and the contents of anthocyanin(cyanidin-3-O-glucoside chloride and cyanidin 3-O-rutinosidechloride) were quantified at 525 nm.
