title: Flavonoid constituents from the roots of Acanthopanax brachypus.
abstract: Two new natural products, (3R)-5,7-dihydroxy-8-(2″-O-veratroyl-β-D-glucopyranosyl)-3-(4'-hydroxyphenyl)-6-methylchroman-4-one (1) and 4'-hydroxyisoflavone-7-O-[α-L-arabinopyranosyl-(1→6)-β-D-glucopyranoside] (2), along with eleven other known flavonoids, were isolated from the roots of Acanthopanax brachypus. Their structures were elucidated on the basis of spectroscopic and chemical evidence.
