Reversed-phase high-performance liquid chromatography coupled with diode array detection (RP-HPLC-DAD) separation of flavonoids present in OJe. UV–Vis spectrum of the eluted molecules was monitored between 200 and 800 nm. The chromatogram was recorded at 278 nm. Flavonoids corresponding to peaks 1–7, expressed in milligrams (mg) per liter (L) of aqueous extract (mg/L), are the following: (1) lucenin-2 (6.2); (2) vicenin-2 (16.1); (3) lucenin-2-4′-methyl ester (9.5); (4) eriocitrin (11.9); (5) narirutin (62.8); (6) hesperidin (56.4); (7) sinensetin (0.52); (8) nobiletin (5.29).
