Abstract
A new triterpenoid, 3,4-seco-lupane-20(29)-ene-3,28-dioic acid, together with three known lignans, (-)-schisandrin B, (-)-sesamin and (-)-syringaresinol, was isolated from the pulp of Acanthopanax senticosus (Rupr. et Maxim) Harms. Their structures were elucidated by means of physicochemical properties and spectroscopic methods (1D, 2D-NMR and MS).
