Phenolic Constituents from Ailanthus fordii Nooteboom
常绿臭椿的酚类成分研究

Five phenolic compounds, quercitrin (1), myricitrin (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 of Ailanthus 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.
