Abstract:Five phenolic compounds, quercitrin （1）, myficitrin （2）, afzelin （3）, (＋)-gallocatechin （4）, and 3-chloro-4-hydroxybenzoic acid （5）, together with daucosterol （6）, were isolated from ethyl acetate fraction of ethanol extract ofA ilanthus fordii twigs. Their structures were elucidated by spectroscopic evidence （IR, NMR, MS, etc） and comparison of their spectral data with those of the literatures. Compounds 1-5 were isolated from this genus for the first time.
