Two new acylated stilbene glucosides, (E)‐3‐O‐methylresveratrol 5‐O‐β‐D‐apiofuranosyl‐(1→6)‐β‐D‐(2″‐vanilloyl)glucopyranoside (1) and (E)‐3‐O‐methylresveratrol 5‐O‐α‐L‐rhamnopyranosyl‐(1→6)‐β‐D‐2″‐[(E)‐feruloyl]glucopyranoside (2), together with five known compounds 2‐methoxyphenyl β‐D‐glucopyranoside, (−)‐syringaresinol‐4,4′‐bis‐O‐β‐D‐glucopyranoside, acantrifoside A, β‐sitosterol, and daucosterol, were isolated from the EtOH extract of Acanthopanax brachypus. Their structures were characterized by means of spectroscopic methods, especially by ^1^H‐, ^13^C‐, 2D‐NMR, and HR‐MS, as well as by chemical methods and comparison with literature data.
