(A). Structures of the compounds isolated from E. chinensis. Red represents triterpenes (1–3), pink represents flavonoids(4–13), and blue represents other types of compounds(14–23).(B–C). Chemical fingerprint of EtOH crude extracts (B) and EtOAc fractions (C). Blue numbers represent identified compounds. The position of peaks corresponding to compounds were indicated by orange arrows and number (retention time).
