The HPLC chromatograms of the phenolic compounds in LCPE. While the orange line represents the chromatogram following the reaction with the DPPH solution, the blue line represents the initial chromatogram of LCPE before the reaction. The compounds detected at the 284 nm wavelength are chlorogenic acid (1), sweroside (2), isoliquiritin (3), liquiritin (4), narirutin (5), isochlorogenic acid (6), quercitrin (7), isorhamnetin (8), isoliquiritigenin (9), arctiin (10), kaempferol-3-O-rutinoside (11), hesperidin (12), and arctigenin (13).
