A New Neolignan Glycoside from the Roots of Acanthopanax brachypus

A new neolignan glycoside, named as brachyposide A, was isolated from the EtOH extract of the roots of Acanthopanax brachypus, together with nine known compounds. The structure of brachyposide A was characterized by spectroscopic means as (7S,8S)-A7′-2,9,9′-trihydroxy-7-O-3′,8-O-4′-neolignan-4-O-Beta-D-apiofuranosyl-(1→6)-Beta-D-glucopyranoside. The known compounds were identified by comparing their spectral data with those of authentic samples or literature data.
