Three new compounds including two phenylethanoid glycosides derivatives, forsyside A (1) and forsyside B (2), together with a sesquiterpene forsysacid A (3) were isolated from the EtOH extract of the fruits of Forsythia suspensa. Their structures were elucidated from analysis of UV, IR, HRESIMS, and 1D/2D NMR data. The absolute configurations of 1 and 3 were determined by quantum electronic circular dichroism (ECD) calculation, and compound 2 was determined by the ECD exciton chirality method. In addition, all compounds were evaluated for their hepatoprotective activity against N-acetyl-p- aminophenol-induced (APAP) HepG2 cell injury, and compound 2 showed significant activity at a concentration of 10 μmol• L –1.

Key words: Forsythia suspensa, phenylethanoid glycosides derivative, sesquiterpene, hepatoprotective activity
