Phytochemical investigation of the stem bark of Acanthopanax brachypus afforded a new labdanetype diterpene glycoside, 3α‐ trans ‐sinapoyloxy‐jhanol 18‐ O ‐β‐D‐glucopyranoside ( 1 ), together with four known compounds, including one diterpene acid, acanthoic acid ( 2 ), one coumarin, isofraxidin ( 3 ), one phenolic glycoside, sasanquin ( 4 ), as well as one chalcone glycoside, okanin 4‐methyl ether‐3′‐ O ‐β‐D‐glucopyranoside ( 5 ). All of the structures were characterized by means of spectroscopic methods, including 1 H, 13 C, 2D‐NMR and HR‐MS, as well as chemical methods and comparison with the literature data.
