Abstract: Phytochemical investigation of the leaves of Acanthopanax henryi led to the isolation of 23 compounds,including three flavonoids (1-3),one organic acid (4),sixteen triterpenoid saponins (5-20),one anthraquinone (21),one steroidal glycoside (22) and one cerebroside (23).The structures of the isolates were elucidated by spectroscopic methods and comparison with the reported spectral data.All of these compounds except for 1-3,10 and 23 have previously been isolated from A.henryi. Compounds 5,6,11,12,14,15,17,19 and 20 have been reported from the Acanthopanax genus and compounds 8,13,and 21 are new compounds within Araliaceae.The chemotaxonomic significance of this investigation based on the isolated compounds is summarized.
