Chromatogram of LCEE. LCEE (5 μg) was injected onto HPLC with the following conditions: system, Shimadzu LC–10AVP (Kyoto, Japan); column, TSK-GEL ODS-80TS (4.6 × 250 mm, Tosoh, Tokyo); mobile phase, 0.5% AcOH/0.5% AcOH in CH3OH 85 : 15; flow rate, 1.0 mL/min; column temperature, 40°C; and detection, 520 nm. Peak at 9.0 min was identified as cyanidin 3-O-glucoside (C3G). LCEE: Lonicera caerulea var. emphyllocalyx extract; HPLC: high-performance liquid chromatography.
