Representative HPLC chromatogram of PA (A) and crude water extract of LA (B). Waters Alliance 2695 separations module equipped with Empower software hyphened with quaternary pumps, an automatic injector, a Waters 2998 photodiode array (PDA) detector at 190–800 nm, and a 250 mm × 4.6 mm × 5 μm Platisil ODS C18 column was used for the separation. HPLC analysis conditions: Acetic acid water ((A), 0.1%)-acetonitrile (B), 0~60 min (5~25% (A)); flow velocity: 1 mL/min, 5 μL injection; wavelength of detection: 254 nm; column temperature: 30 °C.
