Objective To study the chemical constituents from Ciwujia (Acanthopanax senticosus). Methods The chemical constituents were separated and purified by Sephadex LH-20, silica gel, semi-prepared HPLC, and other chromatography techniques. Their structures were elucidated by their physicochemical properties and NMR data. Results Twenty-one compounds were isolated from the 60% ethanol extract and identified as (+)-isolariciresinol (1), dihydrodehydrodiconiferyl alcohol (2), melianoninol (3), vanillil (4), 2,3-dichloroquinoxaline (5), 1,5-di-O-caffeoylquinic acid (6), protocatechuylaldehyde (7), 3-carboxy-6,7-dihydroxy-1-(3',4'-dihydroxyphenyl)-naphthalene (8), ethylcaffeate (9), 5,6,7-trimethoxycoumarin (10), emodin-1-O-β-D-glucopyranoside (11), p-coumaric acid (12), aesculetin (13), methyl 3,5-dihydroxy-4-methoxybenzoate (14), isofraxidin (15), (-)-syringaresinol (16), (+)-syringaresinol (17), trans-caffeicacid (18), emodin (19), vanillic acid (20) and methyl caffeate (21). Conclusion Compounds 1, 3-5, 7-11, 13, 14 are isolated from the genus of Acanthopanax for the first time.
