Phytochemical constituents were isolated from the fruits of Acanthopanax senticosus by repeated chromatography and prep-HPLC. Their structures were identified as β-sitosterol (1), daucosterol (2), p-hydroxybenzoic acid (3), vanillic acid (4), uracil (5), eleutheroside K (6), songoroside A (7), copteroside B (8) and myo-inositol (9) by spectroscopic analysis. Among them, p-hydroxybenzoic acid (3), eleutheroside K (6) and songoroside A (7) were isolated for the first time from the fruits of A. senticosus, and songoroside A (7) was isolated for the first time from Acanthopanax species.   Key words: Acanthopanax senticosus, Araliaceae, repeated chromatography, songoroside A.
